Parallel Port
A low speed port, usually located on the rear of a computer, which usually connects to printers. Parallel ports transmit data simultaneously over eight “parallel
wires” one byte at a time (as opposed to a serial port, which transmits data one bit at a time).
Parity Bit
Parity is a process for detecting whether bits of data have been altered during transmission. A Parity Bit is a non-data bit that is added to a group of data bits to
check for transmission errors. Parity Bits are used in Parity checking which is an error-checking method in asynchronous transmission. The parity bit tells the
receiving end of a transmission whether there should be an even or odd number of bits contained in that transmission.
PIN
Personal Identification Number.
PING
(Packet INternet Groper) An Internet utility used to determine whether a particular IP address is online. It is used to test and debug a network by sending out a
packet and waiting for a response. A program used to test whether or not a network component is available.
PPP
(Point-to-Point Protocol) The most common method for connecting to the Internet. PPP provides serial line (dial-up) connectivity, authentication, compression
and encryption between two computers and can handle several protocols simultaneously.
Protocol
Hardware and software standards that govern transmission between two communications devices. There are several layers, or levels, of functionality in a
protocol. Each layer may be available, as a separate software component, or several layers may be combined into one.
Public IP Address
See Routable IP Address.
RAM
Random Access Memory is the working memory of the computer where you can enter information and call up data.
Routable IP Address (Public IP Address)
A communications protocol that contains a network address as well as a device address, allowing data to be routed from one network to another. Examples of
routable protocols are SNA, OSI, TCP/IP, XNS, IPX, AppleTalk and DECnet.
RS-232
A communication standard for digital data. Specifies a number of signal and control lines. RS-232 is often associated with a 25-pin connector called DB-25.
