problem. When devices within your network request

 

information from the Internet, the requests are forwarded

 

to the Internet under the router's IP address. NAT

 

distributes the responses to the proper IP addresses

 

within your network.

Network

A network consists of a collection of two or more devices,

 

people, or components that communicate with each

 

other over physical or virtual media. The most common

 

types of network are:

 

LAN – (local area network): Computers are in close

 

distance to one another. They are usually in the same

 

office space, room, or building.

 

WAN – (wide area network): The computers are in

 

different geographic locations and are connected by

 

telephone lines or radio waves.

NWay Protocol

A network protocol that can automatically negotiate the

 

highest possible transmission speed between two

 

devices.

P

PCM

PCM (Pulse Code Modulation) is a technique for

 

converting analog audio signals into digital form for

 

transmission.

PING

Packet Internet Groper, a utility used to determine

 

whether a specific IP address is accessible. It functions

 

by sending a packet to the specified address and waits

 

for a reply. It is primarily used to troubleshoot Internet

 

connections.

PPPoE

Point-to-Point Protocol over Ethernet. PPPoE is a

 

specification for connecting the users on an Ethernet to

 

the Internet through a common broadband medium, such

 

as DSL or cable modem. All the users over the Ethernet

 

share a common connection.

Protocol

Communication on the network is governed by sets of

 

rules called protocols. Protocols provide the guidelines

 

devices use to communicate with each other, and thus

 

they have different functions. Some protocols are
