network appear to the Internet as a single address. For
routing messages properly within your network, each device
requires a unique IP address. But the addresses may not be
valid outside your network. NAT solves the 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.
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.
A network protocol that can automatically negotiate the
highest possible transmission speed between two devices.
PCM (Pulse Code Modulation) is a technique for converting
analog audio signals into digital form for transmission.
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.
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.
Communication on the network is governed by sets of rules
called protocols. Protocols provide the guidelines devices
