NetBIOS

 

Network Basic Input/Output System. NetBIOS is an extension of the DOS BIOS that

 

 

enables a computer to connect to and communicate with a LAN.

 

 

 

Network

 

Any time you connect 2 or more computers together so that they can share resources,

 

 

you have a computer network. Connect 2 or more networks together and you have an

 

 

internet.

 

 

 

Node

 

Any single computer connected to a network.

 

 

 

Packet Filter

 

A filter that scans packets and decides whether to let them through or not.

 

 

 

PAP

 

Password Authentication Protocol (PAP) is a security protocol that requires users to

 

 

enter a password before accessing a secure system. The user’s name and password

 

 

are sent over the wire to a server where they are compared with a database of user

 

 

account names and passwords. This technique is vulnerable to wiretapping

 

 

(eavesdropping) because the password can be captured and used by someone to log

 

 

onto the system.

 

 

 

Ping Attack

 

An attack that slows down the network until it is unusable. The attacker sends a "ping"

 

 

command to the network repeatedly to slow it down. See also Denial of Service.

the phone line.

 

 

 

POP

 

A Point of Presence is the point where long-distance telephone service providers

POP

 

Post Office Protocol. This is a common protocol used for sending, receiving and

 

 

delivering mail messages.

 

 

 

Port

 

An Internet port refers to a number that is part of a URL, appearing after a colon (:)

 

 

right after the domain name. Every service on an Internet server listens on a particular

 

 

port number on that server. Most services have standard port numbers, e.g., Web

 

 

servers normally listen on port 80.

 

 

 

Port (H/W)

 

An interface on a computer for connecting peripherals or devices to the computer. A

 

 

printer port, for example, is an interface that is designed to have a printer connected to

 

 

it. Ports can be defined by specific hardware (such as a keyboard port) or through

 

 

software.

 

 

 

POTS

 

Plain Old Telephone Service is the analog telephone service that runs over copper

 

 

twisted-pair wires and is based on the original Bell telephone system. Twisted-pair

 

 

wires connect homes and businesses to a neighborhood central office. This is called

 

 

the local loop. The central office is connected to other central offices and long-distance

 

 

facilities.

 

 

 

PPPPoint to Point Protocol. PPP encapsulates and transmits IP (Internet Protocol) datagrams over serial point-to-point links. PPP works with other protocols such as IPX (Internetwork Packet Exchange). The protocol is defined in IETF (Internet Engineering
