Dell PowerEdge 1655MC - Manual (Page 23)

Abbreviation for pound(s).
LED
Abbreviation for light-emitting diode. An electronic device that lights up when a current is passed through it.
local bus
On a system with local-bus expansion capability, certain peripheral devices (such as the video adapter circuitry) can be designed to run much faster than they
would with a traditional expansion bus. Some local-bus designs allow peripherals to run at the same speed and with the same width data path as the
system's microprocessor.
m
Abbreviation for meter(s).
mA
Abbreviation for milliampere(s).
MAC
Abbreviation for Media Access Control.
mAh
Abbreviation for milliampere-hour(s).
math coprocessor
See coprocessor.
Mb
Abbreviation for megabit.
MB
Abbreviation for megabyte(s). The term megabyte means 1,048,576 bytes; however, when referring to hard drive storage, the term is often rounded to mean
1,000,000 bytes.
MB/sec
Abbreviation for megabytes per second.
Mbps

MBR
Abbreviation for master boot record.
memory
A system 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;
for example, an unqualified statement such as "a system with 16 MB of memory" refers to a system with 16 MB of RAM.
memory address
A specific location, usually expressed as a hexadecimal number, in the system's RAM.
memory module
A small circuit board containing DRAM chips that connects to the system board.
MHz
Abbreviation for megahertz.
microprocessor
The primary computational chip inside the system that controls the interpretation and execution of arithmetic and logic functions. Software written for one
microprocessor must usually be revised to run on another microprocessor. CPU is a synonym for microprocessor.
mirroring
A type of data redundancy that uses a set of physical drives to store data and one or more sets of additional drives to store duplicate copies of the data.
Mirroring is the preferred data redundancy technique in lower-capacity systems and in systems where performance is extremely important.
