Parallel
Processes that occur at the same time. For example, a
parallel printer can receive more than one
bit at a time.
Compare with serial.
Peripheral Any hardware device that is attached to the computer, such
as a monitor, printer, plotter, or modem.
Pins Small protrusions located in “male” connectors. “Female”
connectors have small holes for accommodating the pins in
male connectors.
Plug and Play (PnP) A standard that allows a computer system to automatically
configure expansion boards and other devices.
Random-Access
Memory (RAM) Your computer’s primary memory in which program
instructions and data are stored so that they are accessible to
the Central Processing Unit (CPU). RAM is extremely fast,
but does not retain information once its power is removed.
RAM is measured in megabytes (MB).
Screen saver A program that automatically displays moving images on
the monitor after a predefined period of inactivity. Screen
savers prevent a still image, displayed uninterrupted for long
periods of time, from being burned into the screen. To
remove a screen saver from the screen, press a key or move
the pointing device.
SCSI
An abbreviation for Small Computer System Interface,
pronounced “scuzzy.” SCSI provides faster data
transmission rates (up to 80 MB per second) than serial and
parallel ports. In addition, you can attach (or “daisy-chain”)
many devices to a single SCSI port.
Serial
The process of transmitting data one bit at a time. Compare
with parallel.
Server A computer or software application that provides a specific
kind of service to client software running on other
computers.
