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
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 tokenpassing and Carrier Sense Multiple Access with Collision Detec-
tion (CSMA/CD), implemented as token-ring, ARCNET, FDDI, or Ethernet. The Router
Information Protocol (RIP), a part of the Transmission Control Protocol/Internet Proto-
col (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 ad-
dress, 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 be-
tween networks.
S
Server
It is a simple computer that provides services, such as files accessing 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 station includes both physical nodes and addressable logical devices. Work-
stations, single-attach stations, dual-attach stations, and concentrators are FDDI
