M-learning

M-learning or mobile learning is “learning across multiple contexts, through social and content interactions, using personal electronic devices”.[1]:page 4 A form of distance education, m-learners use mobile device educational technology at their convenient time.[2]

M-learning technologies include handheld computers, MP3 players, notebooks, mobile phones and tablets. M-learning focuses on the mobility of the learner, interacting with portable technologies. Using mobile tools for creating learning aids and materials becomes an important part of informal learning.[3]

M-learning is convenient in that it is accessible from virtually anywhere. Sharing is almost instantaneous among everyone using the same content, which leads to the reception of instant feedback and tips. This highly active process has proven to increase exam scores from the fiftieth to the seventieth percentile, and cut the dropout rate in technical fields by 22 percent.[4] M-learning also brings strong portability by replacing books and notes with small devices, filled with tailored learning contents. M-learning has the added benefit of being cost effective, as the price of digital content on tablets is falling sharply compared to the traditional media (books, CD and DVD, etc.). One digital textbook, for instance, costs one-third to half the price of a paper textbook (AFD, 2012), with zero marginal cost.[5]

Some of the possibilities offered by this methodology, according to Fombona, Pascual-Sevillana and González-Videgaray, are a greater and different access to information, along with transcendent innovations, such as the increase of informal and playful activities, iconic virtual, membership of specific groups, and networks of friendly interaction within new scales of values.[6]

MAC address

A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.

Machine

machine (or mechanical device) is a mechanical structure that uses power to apply forces and control movement to perform an intended action. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.

Machine learning

Machine learning (ML) is the study of computer algorithms that improve automatically through experience. It is seen as a part of artificial intelligence. Machine learning algorithms build a model based on sample data, known as “training data”, in order to make predictions or decisions without being explicitly programmed to do so. Machine learning algorithms are used in a wide variety of applications, such as email filtering and computer vision, where it is difficult or unfeasible to develop conventional algorithms to perform the needed tasks.

A subset of machine learning is closely related to computational statistics, which focuses on making predictions using computers; but not all machine learning is statistical learning. The study of mathematical optimization delivers methods, theory and application domains to the field of machine learning. Data mining is a related field of study, focusing on exploratory data analysis through unsupervised learning. In its application across business problems, machine learning is also referred to as predictive analytics.

Magnetic resonance imaging

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy.

Magnetometer

A magnetometer is a device that measures magnetic field or magnetic dipole moment. Some magnetometers measure the direction, strength, or relative change of a magnetic field at a particular location. A compass is one such device, one that measures the direction of an ambient magnetic field, in this case, the Earth’s magnetic field. Other magnetometers measure the magnetic dipole moment of a magnetic material such as a ferromagnet, for example by recording the effect of this magnetic dipole on the induced current in a coil.

Major film studios

Major film studios are production and distribution companies that release a substantial number of films annually and consistently command a significant share of box office revenue in a given market. In the American and international markets, the major film studios, often simply known as the majors, are commonly regarded as the five diversified media conglomerates whose various film production and distribution subsidiaries collectively command approximately 80 to 85% of U.S. box office revenue.[1][2][3][4] The term may also be applied more specifically to the primary motion picture business subsidiary of each respective conglomerate.

Since the dawn of filmmaking, the U.S. film studios have dominated both American cinema and the global film industry.[5] U.S. studios have benefited from a strong first-mover advantage in that they were the first to industrialize filmmaking and master the art of mass-producing and distributing high-quality films with broad cross-cultural appeal.[6] Today, the Big Five majors – Universal Pictures, Paramount Pictures, Warner Bros. Pictures, Walt Disney Pictures and Columbia Pictures – routinely distribute hundreds of films every year into all significant international markets (that is, where discretionary income is high enough for consumers to afford to watch films). It is “nearly impossible” for a film to reach a broad international theatrical audience without being first picked up by one of the majors for distribution.

Manufacturing

Manufacturing is the production of goods through the use of labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).

Manufacturing engineering, or the manufacturing process, are the steps through which raw materials are transformed into a final product. The manufacturing process begins with the product design, and materials specification from which the product is made. These materials are then modified through manufacturing processes to become the required part.

Modern manufacturing includes all intermediate processes required in the production and integration of a product’s components. Some industries, such as semiconductor and steel manufacturers, use the term fabrication instead.

The manufacturing sector is closely connected with the engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing, Pfizer, Precision Castparts, and Fiat Chrysler Automobiles. Examples in Europe include Volkswagen Group, Siemens, BASF and Michelin. Examples in Asia include Toyota, Yamaha, Panasonic, LG, Samsung and Tata Motors.

MariaDB

MariaDB is a community-developed, commercially supported fork of the MySQL relational database management system (RDBMS), intended to remain free and open-source software under the GNU General Public License. Development is led by some of the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle Corporation in 2009.

MariaDB intended to maintain high compatibility with MySQL, ensuring a drop-in replacement capability with library binary parity and exact matching with MySQL APIs and commands. However, new features diverge more. It includes new storage engines like Aria, ColumnStore, and MyRocks.

Its lead developer/CTO is Michael “Monty” Widenius, one of the founders of MySQL AB and the founder of Monty Program AB. On 16 January 2008, MySQL AB announced that it had agreed to be acquired by Sun Microsystems for approximately $1 billion. The acquisition completed on 26 February 2008. Sun was then bought the following year by Oracle Corporation. MariaDB is named after Monty’s younger daughter, Maria. (MySQL is named after his other daughter, My.)

Mass media

Mass media refers to a diverse array of media technologies that reach a large audience via mass communication. The technologies through which this communication takes place include a variety of outlets.

Broadcast media transmit information electronically via media such as filmsradio, recorded music, or televisionDigital media comprises both Internet and mobile mass communication. Internet media comprise such services as emailsocial media sites, websites, and Internet-based radio and television. Many other mass media outlets have an additional presence on the web, by such means as linking to or running TV ads online, or distributing QR Codes in outdoor or print media to direct mobile users to a website. In this way, they can use the easy accessibility and outreach capabilities the Internet affords, as thereby easily broadcast information throughout many different regions of the world simultaneously and cost-efficiently. Outdoor media transmit information via such media as AR advertisingbillboardsblimps; flying billboards (signs in tow of airplanes); placards or kiosks placed inside and outside buses, commercial buildings, shops, sports stadiums, subway cars, or trains; signs; or skywriting. Print media transmit information via physical objects, such as bookscomicsmagazinesnewspapers, or pamphlets. Event organizing and public speaking can also be considered forms of mass media.

The organizations that control these technologies, such as movie studios, publishing companies, and radio and television stations, are also known as the mass media.

Mass storage

In computing, mass storage refers to the storage of large amounts of data in a persisting and machine-readable fashion. In general the term is uses as large in relation to contemporaneous disk drives, but it has been used large in relation to RAM as for example with floppy disks.

Devices and/or systems that have been described as mass storage include tape libraries, RAID systems, and a variety of computer drives such as hard disk drives, magnetic tape drives, magneto-optical disc drives, optical disc drives, memory cards, and solid-state drives. It also includes experimental forms like holographic memory. Mass storage includes devices with removable and non-removable media.[1][2] It does not include random access memory (RAM).

There are two broad classes of mass storage: local data in devices such as smartphones or computers, and enterprise servers and data centers for the cloud. For local storage, SSDs are on the way to replacing HDDs. Considering the mobile segment from phones to notebooks, the majority of systems today is based on NAND Flash. As for Enterprise and data centers, storage tiers have established using a mix of SSD and HDD.

Mechanical engineering, one of the oldest and broadest engineering disciplines, combines engineering physics and mathematics principals with materials science to design, analyze, manufacture and maintain mechanical systems. It is one of the oldest and broadest of the engineering disciplines.

Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyze, manufacture, and maintain mechanical systems.[1] It is one of the oldest and broadest of the engineering branches.

The mechanical engineering field requires an understanding of core areas including mechanics, dynamics, thermodynamics, materials science, structural analysis, and electricity. In addition to these core principles, mechanical engineers use tools such as computer-aided design (CAD), computer-aided manufacturing (CAM), and product lifecycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons, and others. It is the branch of engineering that involves the design, production, and operation of machinery.[2][3]

Mechanical engineering emerged as a field during the Industrial Revolution in Europe in the 18th century; however, its development can be traced back several thousand years around the world. In the 19th century, developments in physics led to the development of mechanical engineering science. The field has continually evolved to incorporate advancements; today mechanical engineers are pursuing developments in such areas as composites, mechatronics, and nanotechnology. It also overlaps with aerospace engineering, metallurgical engineering, civil engineering, electrical engineering, manufacturing engineering, chemical engineering, industrial engineering, and other engineering disciplines to varying amounts. Mechanical engineers may also work in the field of biomedical engineering, specifically with biomechanics, transport phenomena, biomechatronics, bionanotechnology, and modelling of biological systems.

https://en.m.wikipedia.org/wiki/Mechanical_engineering

Mechatronics, which is also called mechatronic engineering, is a multidisciplinary branch of engineering that focuses on the engineering of both electrical and mechanical systems, and also includes a combination of robotics, electronics, computer, telecommunications, systems, control, and product engineering. As technology advances over time, various subfields of engineering have succeeded in both adapting and multiplying. The intention of mechatronics is to produce a design solution that unifies each of these various subfields. Originally, the field of mechatronics was intended to be nothing more than a combination of mechanics and electronics, hence the name being a portmanteau of mechanics and electronics; however, as the complexity of technical systems continued to evolve, the definition had been broadened to include more technical areas.

Media player software

Media player is a type of application software for playing multimedia computer files like audio and video files. Media players commonly display standard media control icons known from physical devices such as tape recorders and CD players, such as play, pause, fastforward, backforward, and stop buttons. In addition, they generally have progress bars (or “playback bars”) to locate the current position in the duration of the media file.

Mainstream operating systems have at least one default media player. For example, Windows comes with Windows Media Player, Microsoft Movies & TV and Groove Music, while macOS comes with QuickTime Player and Music. Linux distributions come with different media players, such as SMPlayer, Amarok, Audacious, Banshee, MPlayer, mpv, Rhythmbox, Totem, VLC media player, and xine. Android comes with Google Play Music for audio and Google Photos for video.

Medical device

A medical device is any device intended to be used for medical purposes. Medical devices benefit patients by helping health care providers diagnose and treat patients and helping patients overcome sickness or disease, improving their quality of life. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase.

Medical imaging

Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging.

Microblogging

Microblogging is an online broadcast medium that exists as a specific form of blogging. A micro-blog differs from a traditional blog in that its content is typically smaller in both actual and aggregated file size. Micro-blogs “allow users to exchange small elements of content such as short sentences, individual images, or video links”,[1] which may be the major reason for their popularity.[2] These small messages are sometimes called micro posts.[1][3]

As with traditional blogging, micro-bloggers post about topics ranging from the simple, such as “what I’m doing right now”, to the thematic, such as “sports cars”. Commercial micro-blogs also exist to promote websites, services, and products, and to promote collaboration within an organization.

Some microblogging services offer features such as privacy settings, which allow users to control who can read their micro-blogs, or alternative ways of publishing entries besides the web-based interface. These may include text messaging, instant messaging, E-mail, digital audio or digital video.

Micropayment

A micropayment is a financial transaction involving a very small sum of money and usually one that occurs online. A number of micropayment systems were proposed and developed in the mid-to-late 1990s, all of which were ultimately unsuccessful. A second generation of micropayment systems emerged in the 2010s.

While micropayments were originally envisioned to involve very small sums of money, practical systems to allow transactions of less than US$1 have seen little success.[1] One problem that has prevented the emergence of micropayment systems is a need to keep costs for individual transactions low,[2] which is impractical when transacting such small sums[3] even if the transaction fee is just a few cents.

Microtransaction

Microtransactions, often abbreviated as MTX,[1][2] are a business model where users can purchase virtual goods with micropayments. Microtransactions are often used in free-to-play games to provide a revenue source for the developers. While microtransactions are a staple of the mobile app market, they are also seen on PC software such as Valve’s Steam digital distribution platform, as well as console gaming.

Free-to-play games that include a microtransaction model are sometimes referred to as “freemium”. Another term, “pay-to-win”, is sometimes used pejoratively to refer to games where buying items in-game can give a player a disproportionate advantage over other players,[3] particularly if the items cannot be obtained through free means. The objective with a free-to-play microtransaction model is to involve more players in the game by providing desirable items or features that players can purchase if they lack the skill or available time to earn these through regular game play. Also, presumably the game developer’s marketing strategy is that in the long term, the revenue from a micro transaction system will outweigh the revenue from a one-time-purchase game.

Microwaves are a form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter; with frequencies between 300 MHz (1 m) and 300 GHz (1 mm). Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio-frequency engineering is the range between 1 and 100 GHz (wavelengths between 0.3 m and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.

Unlike text-only SMS, MMS can deliver a variety of media, including up to forty seconds of video, one image, a slideshow[2] of multiple images, or audio. The first MMS-capable phones were introduced around 2002 in conjunction with the first GSM network. The Sony Ericsson T68i is widely believed to be the first MMS-capable cell phone, while many more hit North American markets beginning in 2004 and 2005.

The most common use involves sending photographs from camera-equipped handsets.[citation needed] Media companies have utilized MMS on a commercial basis as a method of delivering news and entertainment content, and retailers have deployed it as a tool for delivering scannable coupon codes, product images, videos, and other information.

The 3GPP and WAP groups fostered the development of the MMS standard, which is now continued by the Open Mobile Alliance (OMA).

Mobile app

A mobile application, also referred to as a mobile app or simply an app, is a computer program or software application designed to run on a mobile device such as a phone, tablet, or watch. Apps were originally intended for productivity assistance such as email, calendar, and contact databases, but the public demand for apps caused rapid expansion into other areas such as mobile games, factory automation, GPS and location-based services, order-tracking, and ticket purchases, so that there are now millions of apps available. Apps are generally downloaded from application distribution platforms which are operated by the owner of the mobile operating system, such as the App Store (iOS) or Google Play Store. Some apps are free, and others have a price, with the profit being split between the application’s creator and the distribution platform. Mobile applications often stand in contrast to desktop applications which are designed to run on desktop computers, and web applications which run in mobile web browsers rather than directly on the mobile device.

In 2009, technology columnist David Pogue stated that smartphones could be nicknamed “app phones” to distinguish them from earlier less-sophisticated smartphones.[1] The term “app”, short for “software application”, has since become very popular; in 2010, it was listed as “Word of the Year” by the American Dialect Society.

Mobile broadband

Mobile broadband is the marketing term for wireless Internet access through a portable modem, USB wireless modem, or a tablet/smartphone or other mobile device. The first wireless Internet access became available in 1991 as part of the second generation (2G) of mobile phone technology. Higher speeds became available in 2001 and 2006 as part of the third (3G) and fourth (4G) generations. In 2011, 90% of the world’s population lived in areas with 2G coverage, while 45% lived in areas with 2G and 3G coverage.[1] Mobile broadband uses the spectrum of 225 MHz to 3700 MHz.[2]

Mobile collaboration

Mobile collaboration is a technology-based process of communicating using electronic assets and accompanying software designed for use in remote locations. Newest generation hand-held electronic devices feature video, audio, and telestration (on-screen drawing) capabilities broadcast over secure networks, enabling multi-party conferencing in real time (although real time communication is not a strict requirement of mobile collaboration and may not be applicable or practical in many collaboration scenarios).

Differing from traditional video conferencing, mobile collaboration utilizes wireless, cellular and broadband technologies enabling effective collaboration independent of location. Where traditional video conferencing has been limited to boardrooms, offices, and lecture theatres, recent technological advancements have extended the capabilities of video conferencing for use with discreet, hand-held mobile devices, permitting true mobile collaborative possibilities.

Mobile computing

Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage, which allows for the transmission of data, voice, and video. Mobile computing involves mobile communication, mobile hardware, and mobile software. Communication issues include ad hoc networks and infrastructure networks as well as communication properties, protocols, data formats, and concrete technologies. Hardware includes mobile devices or device components. Mobile software deals with the characteristics and requirements of mobile applications.

https://en.m.wikipedia.org/wiki/Mobile_computing

Mobile device

A mobile device (or handheld computer) is a computer small enough to hold and operate in the hand. Typically, any handheld computer device will have an LCD or OLED flatscreen interface, providing a touchscreen interface with digital buttons and keyboard or physical buttons along with a physical keyboard. Many such devices can connect to the Internet and interconnect with other devices such as car entertainment systems or headsets via Wi-Fi, Bluetooth, cellular networks or near field communication (NFC). Integrated cameras, the ability to place and receive voice and video telephone calls, video games, and Global Positioning System (GPS) capabilities are common. Power is typically provided by a lithium-ion battery. Mobile devices may run mobile operating systems that allow third-party apps specialized for said capabilities to be installed and run.

Early smartphones were joined in the late 2000s by larger, but otherwise essentially the same, tablets. Input and output is now usually via a touch-screen interface. Phones/tablets and personal digital assistants may provide much of the functionality of a laptop/desktop computer but more conveniently, in addition to exclusive features. Enterprise digital assistants can provide additional business functionality such as integrated data capture via barcode, RFID and smart card readers. By 2010, mobile devices often contained sensors such as accelerometers, magnetometers and gyroscopes, allowing detection of orientation and motion. Mobile devices may provide biometric user authentication such as face recognition or fingerprint recognition.

Major global manufacturers of mobile devices are Apple, Samsung, Huawei, Xiaomi, Sony, Google, HTC, LG, TCL, Motorola Mobility and Nokia.

Mobile OS

mobile operating system (or mobile OS) is an operating system for mobile phones, tablets, smartwatches, 2-in-1 PCs (that can be convert to a laptop mode or detach and work as a tablet mode) or other mobile devices. While computers such as typical laptops are ‘mobile’, the operating systems usually used on them are not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This distinction is becoming blurred in some newer operating systems that are hybrids made for both uses.

Mobile operating systems combine features of a personal computer operating system with other features useful for mobile or handheld use; usually including, and most of the following considered essential in modern mobile systems; a wireless inbuilt modem and SIM tray for telephony and data connection, By Q1 2018, over 383 million smartphones were sold with 86.2 percent running Android and 12.9 percent running iOS. Android alone is more popular than the popular desktop operating system Windows, and in general smartphone use (even without tablets) outnumber desktop use.

Mobile payment

Mobile payment (also referred to as mobile money, mobile money transfer, and mobile wallet) generally refer to payment services operated under financial regulation and performed from or via a mobile device. Instead of paying with cash, cheque, or credit cards, a consumer can use a mobile to pay for a wide range of services and digital or hard goods. Although the concept of using non-coin-based currency systems has a long history,[1] it is only in the 21st century that the technology to support such systems has become widely available.

Mobile phone

mobile phonecellular phone, cell phonecellphone, or hand phone, sometimes shortened to simply mobilecell or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, and, therefore, mobile telephones are called cellular telephones or cell phones, in North America. In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games, and digital photography. Mobile phones offering only those capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.

https://en.m.wikipedia.org/wiki/Mobile_phone

Mobile telephony

Mobile telephony is the provision of telephone services to phones which may move around freely rather than stay fixed in one location. Telephony is supposed to specifically point to a voice-only service or connection, though sometimes the line may blur.

Mobile phones connect to a terrestrial cellular network of base stations (cell sites), whereas satellite phones connect to orbiting satellites. Both networks are interconnected to the public switched telephone network (PSTN) to allow any phone in the world to be dialed.

In 2010 there were estimated to be five billion mobile cellular subscriptions in the world.

Moore’s law

Moore’s law is the observation that the number of transistors in a dense integrated circuit (IC) doubles about every two years. Moore’s law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production.

The observation is named after Gordon Moore, the co-founder of Fairchild Semiconductor and former CEO and co-founder of Intel, who in 1965 posited a doubling every year in the number of components per integrated circuit,[a] and projected this rate of growth would continue for at least another decade. In 1975, looking forward to the next decade, he revised the forecast to doubling every two years, a compound annual growth rate (CAGR) of 41%. While Moore did not use empirical evidence in forecasting that the historical trend would continue, his prediction held since 1975 and has since become known as a “law.”

Moore’s prediction has been used in the semiconductor industry to guide long-term planning and to set targets for research and development, thus functioning a bit like a self-fulfilling prophecy. Advancements in digital electronics, such as the reduction in quality-adjusted microprocessor prices, the increase in memory capacity (RAM and flash), the improvement of sensors, and even the number and size of pixels in digital cameras, are strongly linked to Moore’s law. These step changes in digital electronics have been a driving force of technological and social change, productivity, and economic growth.

Motherboard

A motherboard (also called mainboard, main circuit board, system board, baseboard, planar board, logic board, or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset’s input/output and memory controllers, interface connectors, and other components integrated for general use.

Motherboard means specifically a PCB with expansion capabilities. As the name suggests, this board is often referred to as the “mother” of all components attached to it, which often include peripherals, interface cards, and daughtercards: sound cards, video cards, network cards, host bus adapters, TV tuner cards, IEEE 1394 cards; and a variety of other custom components.

Motion Picture Association

The Motion Picture Association (MPA)[1][2] is an American trade association representing the five major film studios of the United States, as well as the video streaming service Netflix. Founded in 1922 as the Motion Picture Producers and Distributors of America (MPPDA) and known as the Motion Picture Association of America (MPAA) from 1945 until September 2019,[3] its original goal was to ensure the viability of the American film industry. In addition, the MPA established guidelines for film content which resulted in the creation of the Production Code in 1930. This code, also known as the Hays Code, was replaced by a voluntary film rating system in 1968, which is managed by the Classification and Rating Administration (CARA).

More recently, the MPA has advocated for the motion picture and television industry, with the goals of promoting effective copyright protection, reducing piracy, and expanding market access. It has long worked to curb copyright infringement, including recent attempts to limit the sharing of copyrighted works via peer-to-peer file-sharing networks and by streaming from pirate sites. Former United States Ambassador to France Charles Rivkin is the chairman and CEO.

Motorcycle

A motorcycle, often called a motorbike, bike, or cycle, is a two- or three-wheeled motor vehicle.[1][2][3] Motorcycle design varies greatly to suit a range of different purposes: long-distance travel, commuting, cruising, sport, including racing, and off-road riding. Motorcycling is riding a motorcycle and being involved in other related social activity such as joining a motorcycle club and attending motorcycle rallies.

The 1885 Daimler Reitwagen made by Gottlieb Daimler and Wilhelm Maybach in Germany was the first internal combustion, petroleum-fueled motorcycle. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle.[4][5]

In 2014, the three top motorcycle producers globally by volume were Honda (28%), Yamaha (17%) (both from Japan), and Hero MotoCorp (India).[6] In developing countries, motorcycles are considered utilitarian due to lower prices and greater fuel economy. Of all the motorcycles in the world, 58% are in the Asia-Pacific and Southern and Eastern Asia regions, excluding car-centric Japan.

According to the US Department of Transportation, the number of fatalities per vehicle mile traveled was 37 times higher for motorcycles than for cars.[7]

Motorola Mobility

Motorola Mobility LLC, marketed as Motorola, is an American consumer electronics and telecommunications company, and a subsidiary of Chinese multinational technology company Lenovo.[3] Motorola primarily manufactures smartphones and other mobile devices running the Android operating system developed by Google.

Motorola Mobility was formed on January 4, 2011, after a split of Motorola into two separate companies, with Motorola Mobility assuming the company’s consumer-oriented product lines (including its mobile phone business, as well as its cable modems and pay television set-top boxes), while Motorola Solutions assuming the company’s enterprise-oriented product lines.

In May 2012 Google acquired Motorola Mobility for US$12.5 billion; the main intent of the purchase was to gain Motorola’s patent portfolio, in order to protect other Android vendors from litigation. Under Google, Motorola increased its focus on the entry-level smartphone market, and under the Google ATAP division, began development on Project Ara—a platform for modular smartphones with interchangeable components. Shortly after the purchase, Google sold Motorola Mobility’s cable modem and set-top box business to Arris Group.

Google’s ownership of the company was short-lived. In January 2014, Google announced that it would sell Motorola Mobility to Lenovo for $2.91 billion. The sale, which excluded ATAP and all but 2,000 of Motorola’s patents, was completed on October 30, 2014.[4] Lenovo disclosed an intent to use Motorola Mobility as a way to expand into the United States smartphone market. In August 2015, Lenovo’s existing smartphone division was subsumed by Motorola Mobility.

MP3

MP3 (formally MPEG-1 Audio Layer III or MPEG-2 Audio Layer III)[4] is a coding format for digital audio developed largely by the Fraunhofer Society in Germany, with support from other digital scientists in the US and elsewhere. Originally defined as the third audio format of the MPEG-1 standard, it was retained and further extended — defining additional bit-rates and support for more audio channels — as the third audio format of the subsequent MPEG-2 standard. A third version, known as MPEG 2.5 — extended to better support lower bit rates — is commonly implemented, but is not a recognized standard.

MPEG-4

MPEG-4 is a method of defining compression of audio and visual (AV) digital data. It was introduced in late 1998 and designated a standard for a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC1/SC29/WG11) under the formal standard ISO/IEC 14496 – Coding of audio-visual objects. Uses of MPEG-4 include compression of AV data for web (streaming media) and CD distribution, voice (telephone, videophone) and broadcast television applications. The MPEG-4 standard was developed by a group led by Touradj Ebrahimi (later the JPEG president) and Fernando Pereira.[1]

MSN

MSN (meaning Microsoft Network) is a web portal and related collection of Internet services and apps for Windows and mobile devices, provided by Microsoft and launched on August 24, 1995, the same release date as Windows 95.[2]

The Microsoft Network was initially a subscription-based dial-up online service that later became an Internet service provider named MSN Dial-up. At the same time, the company launched a new web portal named Microsoft Internet Start and set it as the first default home page of Internet Explorer, its web browser. In 1998, Microsoft renamed and moved this web portal to the domain name www.msn.com, where it has remained.[3]

In addition to its original MSN Dial-up service, Microsoft has used the ‘MSN’ brand name for a wide variety of products and services over the years, notably Hotmail (later Outlook.com), Messenger (which was once synonymous with ‘MSN’ in Internet slang and has now been replaced by Skype), and its web search engine, which is now Bing, and several other rebranded and discontinued services.

The current website and suite of apps offered by MSN was first introduced by Microsoft in 2014 as part of a complete redesign and relaunch.[4] MSN is based in the United States and offers international versions of its portal for dozens of countries around the world.[5]

Multimedia

Multimedia is a form of communication that combines different content forms such as text, audio, images, animations, or video into a single presentation, in contrast to traditional mass media, such as printed material or audio recordings. Popular examples of multimedia include video podcasts, audio slideshows, animated shows, and movies.

Multimedia can be recorded for playback on computers, laptops, smartphones, and other electronic devices, either on demand or in real time (streaming). In the early years of multimedia, the term “rich media” was synonymous with interactive multimedia. Over time, hypermedia extensions brought multimedia to the World Wide Web.

Multiplayer video game

A multiplayer video game is a video game in which more than one person can play in the same game environment at the same time, either locally (e.g. New Super Mario Bros. Wii) or online over the internet (e.g. World of Warcraft, Call Of Duty). Multiplayer games usually require players to share the resources of a single game system or use networking technology to play together over a greater distance; players may compete against one or more human contestants, work cooperatively with a human partner to achieve a common goal, or supervise other players’ activity. Multiplayer games allow players interaction with other individuals in partnership, competition, or rivalry, providing them with social communication absent from single-player games.

Music

Music is an art form, and cultural activity, whose medium is sound. General definitions of music include common elements such as pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the “color” of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek μουσική (mousike; “art of the Muses”). See glossary of musical terminology.

Music download

A music download (commonly referred to as a digital download) is the digital transfer of music via the Internet into a device capable of decoding and playing it, such as a personal computer, portable media player, MP3 player or smartphone. This term encompasses both legal downloads and downloads of copyrighted material without permission or legal payment. According to a Nielsen report, downloadable music accounted for 55.9 percent of all music sales in the US in 2012.[nb 1][1] By the beginning of 2011, Apple’s iTunes Store alone made US$1.1 billion of revenue in the first quarter of its fiscal year.[2] Music downloads are typically encoded with modified discrete cosine transform (MDCT) audio data compression, particularly the Advanced Audio Coding (AAC) format used by iTunes as well as the MP3 audio coding format.

Music genre

A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions.[1] It is to be distinguished from musical form and musical style, although in practice these terms are sometimes used interchangeably.[2]

Music can be divided into genres in varying ways, such as into popular music and art music, or religious music and secular music. The artistic nature of music means that these classifications are often subjective and controversial, and some genres may overlap. Academic definitions of the term genre itself vary.

Music industry

The music industry consists of the companies and independent artists that earn money by creating new songs and pieces and arranging live concerts and shows, audio and video recordings, compositions and sheet music, and the organizations and associations that aid and represent music creators. Among the many individuals and organizations that operate in the industry are: the songwriters and composers who create new songs and musical pieces; the singers, musicians, conductors and bandleaders who perform the music; the companies and professionals who create and sell recorded music and/or sheet music (e.g., music publishers, music producers, recording studios, engineers, record labels, retail and online music stores, performance rights organizations); and those that help organize and present live music performances (sound engineers, booking agents, promoters, music venues, road crew).

https://en.m.wikipedia.org/wiki/Music_industry

Music video

A music video is a short film, of variable length, that integrates a song or album[1] with imagery that is produced for promotional or artistic purposes.[2] Modern music videos are primarily made and used as a marketing device intended to promote the sale of music recordings. There are also cases where songs are used in tie-in marketing campaigns that allow them to become more than just a song. Tie-ins and merchandising can be used for toys or for food or other products.

Although the origins of the music video date back to musical short films that first appeared in the 1920s, they again came into prominence in the 1980s when the channel MTV (originally “Music Television”) based its format around the medium. Prior to the 1980s, these kinds of videos were described by various terms including “illustrated song,” “filmed insert,” “promotional (promo) film,” “promotional clip,” “promotional video,” “song video,” “song clip,” or “film clip.”

Myspace

Myspace (originally stylized as MySpace) is an American social networking service. From 2005 to 2008, it was the largest social networking site in the world.[3]

Myspace was acquired by News Corporation in July 2005 for $580 million,[4] and in June 2006 surpassed Yahoo! and Google to become the most visited website in the United States.[5][6] The network generated $800 million in revenue during the 2008 fiscal year.[7] At its peak in April 2008, Myspace and Facebook reached 115 million unique users, and Myspace narrowly lost to the newly emerging Facebook in terms of global users.[8] In May 2009, Facebook surpassed Myspace in the number of unique U.S. visitors.[9] Since then, the number of Myspace users has declined steadily despite several redesigns.[10] By 2019, the number of monthly visitors had dropped to 7 million.[8]

Myspace has had a significant influence on technology, pop culture and music.[11] It was the first social network to reach a global audience. It played a critical role in the early growth of companies like YouTube,[12] and created a developer platform that launched the successes of Zynga, RockYou, and Photobucket, among others.[13]

In June 2009, Myspace employed approximately 1,600 employees.[14][15] In June 2011, Specific Media Group and Justin Timberlake jointly purchased the company for approximately $35 million.[16] On February 11, 2016, it was announced that Myspace and its parent company had been purchased by Time Inc.[17][18] for $87 million. Time Inc. was in turn purchased by the Meredith Corporation on January 31, 2018.

MySQL

MySQL (/ˌmaɪˌɛsˌkjuːˈɛl/)[5] is an open-source relational database management system (RDBMS).[5][6] Its name is a combination of “My”, the name of co-founder Michael Widenius’s daughter,[7] and “SQL”, the abbreviation for Structured Query Language. A relational database organizes data into one or more data tables in which data types may be related to each other; these relations help structure the data. SQL is a language programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer’s storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups.
