Glossary of Terms

PAP:

(Password Authentication Protocol) Authentication scheme for PPP links. A password can be specified for both devices on a remote link. Failure to authenticate will result in a dropped connection prior to start of data transmission.

Physical Address:

An address identifying a single node.

Physical Layer:

Layer 1, the bottom layer of the OSI model, is implemented by the physical channel. The Physical layer insulates Layer 2, the Data Link layer, from medium-dependent physical characteristics such as baseband, broadband or fiber-optic transmission. Layer 1 defines the protocols that govern transmission media and signals.

Point-to-Point:

A circuit connecting two nodes only, or a configuration requiring a separate physical connection between each pair of nodes.

Port:

The physical connector on a device enabling the connection to be made.

Port Multiplier:

A concentrator providing connection to a network for multiple devices.

PostScript:

A printer/display protocol developed by Adobe Corp. PostScript is an actual printing and programming language to display text and graphics. Unlike line/ASCII printers, which print character input verbatim, PostScript printers accept and interpret an entire PostScript page before printing it.

PPP:

Point-to-Point Protocol. The successor to SLIP, PPP provides router-to-router and host-to-network connections over both synchronous and asynchronous circuits.

Print Server:

A dedicated computer that manages printers and print requests from other nodes on the network.

PROM:

Programmable ROM, a read-only memory whose data content can be altered.
