MTU- the Maximum Transmission Unit (MTU) is a term for the size (in bytes) of the largest datagram that can be passed by a layer of a communications protocol. In the Internet Protocol the "path MTU" of an Internet transmission path is defined to be the smallest MTU of any of the IP hops.
MUD- (Multi User Domain or Multi User Dimension or Multi User Dungeon) a realtime, interactive virtual community where the inhabitants assume identities using avatars. Initially, MUDs were almost exclusively devoted to role playing activities, today, however, the term is also synonymous with chat rooms.
Multi Media Card- see MultiMediaCard.
MultiCast- to broadcast an audio or video message over a network using special software such as Real Audio.
multimedia- the use of a computer to display integrated text, graphics, animation and sound. As computers become more sophisticated and less expensive, the potential for use in multimedia presentations such as movies and interactive education increases.
MultiMediaCard- (MMC) a flash memory card that provides storage for cellphones, PDAs and other handheld devices. Introduced in 1997 with a 4MB capacity, the 32x24x1.4mm card weighs less than two grams. By 2005, storage increased to 2GB. The card uses flash memory for read/write applications or ROM chips (ROM-MMC) for static information, the latter widely used for adding applications to a Palm PDA. MultiMediaCards (MMCs) are noted for their high transfer rates, up to 52 MB/sec.
multitasking- the ability for a computer to run more than one application or task at one time. Technically speaking, a computer’s microprocessor executes only one task at a time. However, the CPU quickly alternates operational functions among open programs to give the appearance of simultaneous operation. For example, a user might finish work on a document and print it. While it is printing, she can begin work on another document using a word processing program, play a game, or navigate the World Wide Web.
My Computer- in Windows, a folder, often represented by a computer icon on the desktop, that contains the system’s disk drivers, control panel, printers, and dial-up-networking connections.
