Machine Language:-  The lowest-level computer language, consisting of strings of binary digits and readable by the CPU.

Macintosh:-  Computer developed by Apple Computers. The Macintosh was one of the first computers to use a Graphical User Interface
(GUI)  - Today, Apple continues to produce many different models of Macintosh.

MacOS:-  The operating system produced for their Macintosh computers.

Macro:-  A stored list of commands in a program that can be launched at the push of a button.  Macros used properly can automate
tedious and often repeated tasks.

Mailing List:-  A collection of E-mail addresses of people who have an account with an on-line service or Internet Service Provider.

Mailto:-  Is a clickable function (hyperlink) on a web page that will allow the viewer to send an E-mail message to the person listed as the
mailto contact.

Mainframe:-  A large computer with enormous memory capacity and the ability to handle multiple input-output units.

MBPS:-  Megabits per second (one million bits per second). Speed at which data is transferred.

Media:-  Items used to hold data, including floppy disks, hard disks, tapes, CD-R0Ms, etc.

Megabyte (MB):-  Equal to 1,048,576 bytes, usually rounded off to one million bytes.

Megahertz (MHz):-  One million cycles per second.  Describes the speed at which a computer runs. Abbreviated MHz or Mhz. Do not take
the speed at which a processor runs to be absolute.

Memory:-  A computer device or series of devices that store information.  This is a temporary storage area for information that empties out
when the computer is turned off or re-booted.

Memory Protection:-  A capability of some operating systems to control a program's access to memory, so that one program cannot
corrupt the memory allocated to another program.

Menu:-  A list of options displayed on the computer monitor that you can choose from.

Menu Bar:-  A one-line, horizontal menu at the top of the screen, usually found in GUIs.

Menu Driven:-  A system operated by selecting from a list of options that are displayed on the screen.  It is much more "user friendly" than
Command Driven systems.

Merge:- To combine two or more files into a single file arrangement.

Metafile:-  A vector-based graphic. Metafiles are represented as collections of lines rather than pixels, so you can manipulate them
without the distortions common to bitmap graphics.

MFLOPS:-  Million Floating point Operations Per Second.

Micro Channel Architecture (MCA):-  A non-industrial standard architecture used by some IBM PS/2's.

Microchip:-  A small, silicon object containing microscopic circuitry.

Microcomputer:-  A personal computer containing a central processing unit (CPU) and one or more memory circuits.

Microprocessor:-  A complete central processing unit (CPU) contained on a single silicon chip.

MIDI (Musical Instrument Digital Interface):-  The interface between computers and digital devices that simulate musical instruments.  
This allows your computer to be used as a pseudo-music studio.

MIME:-  Multipurpose Internet Mail Extensions.  A protocol for allowing E-mail messages to contain various types of media (text, audio,
video, images, etc.).

MIPS (Million Instructions Per Second):-  Used to describe speeds at which a CPU can process instructions.

Modem:-   Modulate-Demodulate. A hardware device that allows communication with another computer or fax machine over a telephone
line.

Moderator:-  Someone who controls the posting of messages in a forum or discussion group to ensure conformity with the topic and
policies.

Modified Frequency Modulation (MFM):-  An early standard for hard disk data storage and transfer that is no longer used.

Module:-  A collection of declarations, statements, and procedures stored together as one named unit.

Monitor:-  A video display terminal used to display the visual output of a computer.

Monochrome:-  A monitor that displays only one color. Some monochrome monitors can also display various shades of gray and are
called gray-scale monitors.

MOSAIC:-  a software program designed to provide a user-friendly graphical interface when browsing the World Wide Web.

Mother Board:-  The main circuit board in a computer, also called the system board. The CPU is located on the motherboard.

Mouse:-  A small hand-held device for controlling the cursor movement on the screen by moving the "mouse" back and forth on a flat
surface.

MPEG:-   Motion Picture Experts Group.  A video file format offering excellent quality in a relatively small file.

MS-DOS:-  An operating system developed by Microsoft Corporation.

Multimedia:-  Software application technology that combines text and graphics with sound and animation.  A multimedia PC contains the
hardware to support these capabilities.

Multiprocessor:-  A computer system that uses more than one CPU running in parallel for faster performance.

MultiSync:-  In a monitor, the ability to run at different scan rates, allowing the monitor to display different resolutions.

Multitasking:-  The execution of more than one computer program at a time.  An example would be receiving a fax at the same time you
were printing a document without noticing any delay.  Windows 95 is an example of a true multi-tasking environment.

Multithreading:-  The ability to have more than one task occurring in an application.
