MDA (Monochrome Display Adapter)

megabyte (MB)

An amount of computer memory equal to 220. 1,048,576 bytes = 1024 kilobytes. One megabyte can store more than one million characters.

megahertz (MHz)

One million hertz (one million cycles per second). A measurement of clock speed.

memory

The area within a computer where information is stored while being worked on. It stores information (in the form of data bits) that the CPU and software need to keep running.

Micro Channel Architecture (MCA)

A short-lived 32-bit expansion bus that was a proprietary design of IBM used on the IBM PS/2 computer. By abandoning the open design of the existing PC market, IBM limited the willingness of developers and buyers alike to use MCA.

mouse

Device used with graphical environments to point and select objects on the system's monitor. They come in a variety of shapes and sizes.

MTBF (mean time between failures)

A standard means by which vendors estimate the expected lifespan of a given product line.
