Pipelining improves system performance by allowing the CPU to begin
executing a second instruction before the first is completed. A pipeline can be
likened to an assembly line, with a given part of the pipeline repeatedly
executing a set part of an operation on a series of instructions.
PM timers ( P ower M anagement timers ) are software timers that count down
the number of seconds or minutes until the system times out and enters sleep,
suspend, or doze mode.
PnP is an acronym for Plug and Play, a design standard that has become
ascendant in the industry. Plug and Play devices require little set-up to use.
Novice end users can simply plug them into a computer that is running on a
Plug and Play-aware operating system (such as Windows 95), and go to work.
Devices and operating systems that are not Plug and Play require you to
reconfigure your system each time you add or change any part of your
hardware.
The term RAM ( R andom A ccess M emory), while technically referring to a type
of memory where any byte can be accessed without touching the adjacent
data, is often used to refer to the system’s main memory. This memory is
available to any program running on the computer.
ROM ( R ead- O nly M emory) is a storage chip which contains the BIOS (Basic
Input/Output System), the basic instructions required to boot the computer
and start up the operating system.
SDRAM ( S ynchronous D ynamic RAM ) is so-called because it can keep two
sets of memory addresses open simultaneously. By transferring data alter-
nately from one set of addresses, and then the other, SDRAM cuts down on
the delays associated with non-synchronous RAM, which must close one
address bank before opening the next.
The serial port is so called because it transmits the eight bits of a byte of data
along one wire, and receives data on another single wire (that is, the data is
transmitted in serial form, one bit after another).
SIMM S ingle I n-line M emory M odules are the most common form of RAM.
They must be installed in pairs, and do not have the carrying capacity or the
speed of DIMMs.
