MAPI Messaging Application Programming Interface (application development software feature that builds e-mail capabilities into an existing program)
MathML Mathematical Markup Language ("MathML is a low-level specification for describing mathematics as a basis for machine to machine communication. It provides a much needed foundation for the inclusion of mathematical expressions in Web pages." For more information see: W3C's Math Home Page
MB Megabyte (A digital MB equals 1,048,576 decimal bytes which represents 2 raised to the 20th or 1024 * 1024 bytes; a decimal MB equals 1,000,000 bytes; also see GB & TB)
MBone Multicast Backbone (also see Backbone)
Mbps Megabytes per second (describing the rate at which data is read or transferred)
Total number of hits per month multiplied by web page size in kb (e.g., 10,000 hits by 30kb per page = 300 MB per month (method by which Web Host Service Providers assess fees for Web page publishing on the Internet)

MCIS Microsoft Commercial Internet System
MCSE Microsoft Certified System Engineer
MDA Monochrome Display Adaptor (see also HGB; there may have been a time that there was no color, but we at least HAD hair...)
MDI Multiple-Document Interface (For example, the MDI file in VB [Visual Basic] is designed especially for document-centered applications. MDIs make it possible to open several applications simultaneously or have more than one active window within the space of one application).
Multiple-Document Interface window that is controlled by the MDIClient Window that allows the user to pick images, for example, to add to a working document.
Multiple-Document Interface window placed on top of the client area of an active application.

Megabyte A digital MB equals 1,048,576 decimal bytes which represents 2 raised to the 20th; a decimal MB equals 1,000,000 bytes.

MetaCrawler Internet metasearch (across search engines) engine that scans major search engines, such as: Excite, Galaxy, Go, Google GoTo, HotBot, Lycos, WebCrawler, and Yahoo. You may also search the web using MetaCrawler.
Metafile A file that stores an image in terms of graphical objects (lines, circles, polygons) rather than pixels. When resized, a metafile tends to preserve an image better than bitmap does (also see bitmap).
ME/U Mind EExtension University (cable channel)
MFC a) Microsoft Foundation Classes (programming in Visual C++ 1.0)
MFC b) Multi-Function Centers (combine a laser printer, copier, scanner, and fax/modem all in one).
MFM Modified Frequency Modulation (Disk)
MHZ Megahertz or millions of cycles per second. An approximate assessment of CPU performance. The higher is the speed of the clock the faster the performance of a CPU from the same group. For example, a 100 MHZ 80486DX4 was approximately 50% faster than a 66 MHZ 80486DX2, yet a 100 MHZ Pentium based PC was twice as fast (also see Hz). New groups, such as, Pentium II and Pentium III are much faster than the MHZ number would suggest in comparison to older CPU groups
