NAT Network Address Translator generally applied by a router, that makes
many different IP addresses on an internal 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.
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 syst
em 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.
