MB - Megabyte
MB: Unit of measurement for pieces of information : approximately 1 million bytes or a thousand kilobytes. Often shortened to Meg or just M. See also Gigabyte, Kilobyte, Byte.

Mbps - MegaBits Per Second
Mbps: A measure of speed of information flow over a network (and if it's measured in Mbps, it's reasonably quick.) A Megabit is one million bits. See also bps, Kbps.

Megapixel
megapixel: A million pixels. Often used to measure the quality of digital cameras : the higher the number the better the camera.

MHz - Megahertz
MHz: Millions of cycles per second. Most often used as a measurement of a PC processor chip's speed and power, with bigger numbers meaning more speed and a higher price. See also GHz.

Mobo - Motherboard
Mobo: Abbreviated definition for motherboard (see motherboard).

Motherboard or Mainboard
Motherboard: The motherboard is the main circuit board inside your PC. Every components at some point communicates through the motherboard, either by directly plugging into it or by communicating through one of the motherboards ports. The motherboard is one big communication highway. Its purpose inside your PC is to provide a platform for all the other components and peripherals to talk to each other.

MP3 - MPeg-1 audio layer 3
MPeg: A very popular standard for compressing audio and particularly music files down to a reasonable size with little or no perceptible loss of quality, and the files created using it - "an MP3" is an audio file. See MPEG, Compression.

MPB - Megapixel Banding
"MegaPixel" refers to any digital camera CCD or CMOS sensor with over 1 million pixels. For example the CCD in a 3.34 Megapixel digital camera has 3.34 million individual sensors, each one making up one pixel (short for "Picture Element"). These pixels make up the digital image. To make it easier to find the camera that's right for you we group cameras together into bands (e.g. 3 to 3.9 Megapixel). For the full low-down on the exact effective resolution (e.g. 3.34 Megapixel), see the individual product description.

MPEG - Motion Picture Experts Group
MPEG: pr. "em-peg" A set of standards for compressing video and audio files, and the committee that came up with them. Also, often used to mean movie files created to the MPEG standard.
