Component Object Model
Component Object Model (COM) is a binary-interface technology for software components from Microsoft that enables using objects in a language-neutral way between different programming languages, programming contexts, processes and machines. COM is the basis for other Microsoft domain-specific component technologies including OLE, OLE Automation, ActiveX, COM+, and DCOM as well as implementations such as DirectX, Windows shell, UMDF, Windows Runtime, and Browser Helper Object. COM enables object use with only knowing its interface; not its internal implementation. The component implementer defines interfaces that are separate from the implementation. Support for multiple programming contexts is handled by relying on the object for aspects that would be challenging to implement as a facility. Supporting multiple uses of an object is handled by requiring each object to destroy itself via reference-counting. Access to an object's interfaces (similar to Type conver ...

COM File
A COM file is a type of simple executable file. On the Digital Equipment Corporation (DEC) VAX operating systems of the 1970s, .COM was used as a filename extension for text files containing commands to be issued to the operating system (similar to a batch file). With the introduction of Digital Research's CP/M (a microcomputer operating system modeled after TOPS-10 for the PDP-10), the type of files commonly associated with COM extension changed to that of executable files. This convention was later carried over to DOS. Even when complemented by the more general .exe, EXE file format for executables, the compact COM files remained viable and frequently used under DOS. The .COM file name extension has no relation to the .com (for "commercial") top-level Internet domain name. However, this similarity in name has been exploited by malware writers. DOS binary format The COM format is the original binary executable format used in CP/M (including SCP (operating system), SCP and M ...

Concerned Officers Movement
The Concerned Officers Movement (COM) was an organization of mainly junior officers formed within the United States Armed Forces, U.S. military in the early 1970s. Though its principal purpose was opposition to the U.S. involvement in the Vietnam War, it also fought for First Amendment to the United States Constitution, First Amendment rights within the military. It was initiated in the Washington, D.C., area by commissioned officers who were also Vietnam veteran, Vietnam Veterans, but rapidly expanded throughout all branches and many bases of the U.S. military, ultimately playing an influential role in the Opposition to United States involvement in the Vietnam War, opposition to the Vietnam War. At least two of its chapters expanded their ranks to include Enlisted rank, enlisted personnel (non-officers), in San Diego changing the group's name to Concerned Military, and in Kodiak, Alaska, to Concerned Servicemen's Movement. Founding COMs genesis sprang from the participation of Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston University College Of Communication
__NOTOC__ The Boston University College of Communication (COM) is the communication school of Boston University (BU), a private research university in Boston, Massachusetts. Founded in 1947, it was the first university in the United States to offer a degree in public relations (PR), and the program sets the standard for PR paths across the country. It houses the University's undergraduate and graduate programs in advertising, film and television, journalism, media science, and public relations. Notable alumni * Chet Simmons (COM '52) – first ESPN president, ABC Sports executive, NBC Sports president, USFL commissioner, Sports Broadcasting Hall of Fame in 2010, helped build ABC Sports into a leader in sports programming, developed '' Wide World of Sports'' * Jean Firstenberg (COM '58) – President and CEO of the American Film Institute (1980–2007), only woman to serve * Donald Lambro (COM '62) – chief political correspondent of ''The Washington Times'' * Nina Totenber ...

COM (hardware Interface)
COM (communication port) is the original, yet still common, name of the serial port interface on IBM PC compatible, PC-compatible computers. It can refer not only to physical ports, but also to Hardware emulation, emulated ports, such as ports created by Bluetooth or USB adapters. History The name for the COM port started with the original IBM PC. IBM had called the four well-defined communication RS-232 ports the "COM" ports, starting from COM1 through COM4. In BASICA and PC DOS you can open these ports as "COM1:" through "COM4:", and all PC compatibles using MS-DOS used the same denotation. Most PC-compatible computers in the 1980s and 1990s had one or two COM ports. By 2007, most computers shipped with only one or no physical COM ports. Today, few consumer-grade PC-compatible computers include COM ports, though some of them do still include a COM Pin header, header on the motherboard. After the RS-232 COM port was removed from most consumer-grade computers, an external USB-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer-on-module
A computer-on-module (COM) is a type of single-board computer (SBC), a subtype of an embedded computer system. An extension of the concept of System on a chip, system on chip (SoC) and system in package (SiP), COM lies between a full-up computer and a microcontroller in nature. It is very similar to a system on module (SOM). Design COMs are complete embedded computers built on a single circuit board. The design is centered on a microprocessor with random-access memory, RAM, input/output controllers and all other features needed to be a functional computer on the one board. However, unlike a single-board computer, the COM usually lacks the standard connectors for any input/output peripherals to be attached directly to the board. The module usually needs to be mounted on a carrier board (or "baseboard") which breaks the bus out to standard peripheral connectors. Some COMs also include peripheral connectors. Some can be used without a carrier. A COM solution offers a dense pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Center-of-momentum Frame
In physics, the center-of-momentum frame (COM frame) of a system, also known as zero-momentum frame, is the inertial frame in which the total momentum of the system vanishes. It is unique up to velocity, but not origin. The ''center of momentum'' of a system is not a location, but a collection of relative momenta/velocities: a reference frame. Thus "center of momentum" is a short for "center-of-momentum ".Dynamics and Relativity, J.R. Forshaw, A.G. Smith, Wiley, 2009, A special case of the center-of-momentum frame is the center-of-mass frame: an inertial frame in which the center of mass (which is a single point) remains at the origin. In all center-of-momentum frames, the center of mass is at rest, but it is not necessarily at the origin of the coordinate system. In special relativity, only when the system is isolated is the COM frame necessarily unique. Properties General The center of momentum frame is defined as the inertial frame in which the sum of the linear momen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COM (manga Magazine)
was a monthly manga magazine started in December 1966 by Osamu Tezuka and published by his company Mushi Production. It was started in response to the success of '' Garo'', and as a way for Tezuka and other artists to showcase more avant-garde and experimental works in manga. Seven arcs of Tezuka's famous series '' Phoenix'' were published in the magazine. ''COM'' was particularly influential in amateur manga circles and was a platform for many aspiring manga artists to publish their first professional work. The magazine eventually went bankrupt and its last issue was published in December 1971. History The first issue was the January 1967 issue, published in December 1966. Osamu Tezuka and his publishing company Mushi Production created ''COM'' in reaction to the alternative manga magazine ''Garo'''s popularity, which at that time was around its highest circulation. Tezuka himself was a crossroads with his work, shifting to darker themes influenced by gekiga, targeting the rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collectivité D'outre-mer
The French overseas collectivities ( abbreviated as COM) are first-order administrative divisions of France, like the French regions, but have a semi-autonomous status. The COMs include some former French overseas colonies and other French overseas entities with a particular status, all of which became COMs by constitutional reform on 28 March 2003. The COMs differ from overseas regions and overseas departments, which have the same status as metropolitan France but are located outside Europe. As integral parts of France, overseas collectivities are represented in the National Assembly, Senate and Economic and Social Council. Though some are outside the European Union, all can vote to elect members of the European Parliament (MEPs). (All of France became one multi-member EU constituency in 2019.) The Pacific COMs use the CFP franc, a currency pegged to the euro, whereas the Atlantic COMs use the euro itself. As of 31 March 2011, there were six COMs: * French Polynesia be ...
