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 station includes both physical nodes

 

and addressable logical devices. Workstations, single-attach

 

stations, dual-attach stations, and concentrators are FDDI stations.

Subnet mask

In TCP/IP, the bits used to create the subnet are called the subnet

 

mask.
