M
Mb
— megabit — A measurement of memory chip capacity that equals 1024 Kb.
Mbps
— megabits per second — One million bits per second. This measurement is
typically used for transmission speeds for networks and modems.
MB
— megabyte — A measurement of data storage that equals 1,048,576 bytes. 1 MB
equals 1024 KB. When used to refer to hard drive storage, the term is often rounded to
1,000,000 bytes.
MB/sec
— megabytes per second — One million bytes per second. This measurement

media bay
— A bay that supports devices such as optical drives, a second battery, or a
Dell TravelLite™ module.
memory
— A temporary data storage area inside your computer. Because the data in
memory is not permanent, it is recommended that you frequently save your files while
you are working on them, and always save your files before you shut down the computer.
Your computer can contain several different forms of memory, such as RAM, ROM, and
video memory. Frequently, the word memory is used as a synonym for RAM.
memory address
— A specific location where data is temporarily stored in RAM.
memory mapping
— The process by which the computer assigns memory addresses to
physical locations at start-up. Devices and software can then identify information that
the processor can access.
memory module
— A small circuit board containing memory chips, which connects to
the system board.
MHz
— megahertz — A measure of frequency that equals 1 million cycles per second.
The speeds for computer processors, buses, and interfaces are often measured in MHz.
Mini PCI
— A standard for integrated peripheral devices with an emphasis on
communications such as modems and NICs. A Mini PCI card is a small external card
that is functionally equivalent to a standard PCI expansion card.
Mini-Card —
A small card designed for integrated peripherals, such as
communication NICs. The Mini-Card is functionally equivalent to a standard PCI
expansion card.

MP
— megapixel — A measure of image resolution used for digital cameras.
ms
— millisecond — A measure of time that equals one thousandth of a second.
Access times of storage devices are often measured in ms.
