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
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 responsible for formatting and presenting and presenting data that
will be transferred from file server memory to the file server’s net work adapter Others are
responsible for filtering information between networks and forwarding data to its destination.
Still other protocols dictate how data is transferred across the medium, and how servers respond
to workstation requests and vice versa. Common network protocols responsible for the
presentation and formatting of data for a network operating system are the Internetwork Packet
Exchange (IPX) protocol or the Internet Protocol (IP). Protocols that dictate the format of data for
transferors the medium include token-passing and Carrier Sense Multiple Access with Collision
Detection (CSMA/CD),implemented as token-ring, ARCNET, FDDI, or Ethernet. The Router
Information Protocol (RIP), a part of the Transmission Control Protocol/Internet Protocol
(TCP/IP) suite, forwards packets from one network to another using the same network protocol.
R
RARP Reverse Address Resolution Protocol, a TCP/IP protocol that allows a physical address, such as
an Ethernet address, to be translated into an IP address.
RJ-45 RJ-45 connector is used for Ethernet cable connections.
Router A router is the network software or hardware entity charged with routing packets between
networks.
S
Server It is a simple computer that provides resources, such as files or other information.
SMTP The Simple Mail Transfer Protocol is used for Internet mail.
SNMP Simple Network Management Protocol. SNMP was designed to provide a common foundation
for managing network devices.
Station In LANs, a station consists of a device that can communicate data on the network. In FDDI, a
