Internet

A global TCP/IP network linking millions of computers for communications

purposes.

Internet Engineering Task Force (IETF)

The IETF is the committee that defines standard Internet operating protocols such

as TCP/IP. The IETF is supervised by the Internet Society's Internet Architecture

Board (IAB).

Internet-standard Network Management Framework

Device configuration and monitoring via SNMP.

The Internet Protocol (IP) is the protocol that supports data being sent from one

computer to another on the Internet. Each computer on the Internet has at least one

address that uniquely identifies it from all other computers on the Internet. When

you send or receive data, the message gets divided into units called packets. Each

of these packets contains both the sender's Internet address and the receiver's

address.

IP is a connectionless protocol, which means that there is no established connection

betweenthe end points that arecommunicating.Eachpacket thattravelsthroughthe

Internet is treated as an independent unit of data without any relation to any other

unit of data. In the Open Systems Interconnection (OSI) communication model, IP

is in layer 3, the Networking Layer.

IP address

The Internet Protocol address is a unique identifier that allows communication over

the Internet to be directed to the appropriate destination. Every computer on the

Internet must have a unique IP address. IP addresses are allocated by an Internet

service provider (ISP) in the following format: nnn.nnn.nnn.nnn, where nnn is a

numeric value from 0 to 255. IP addressing might be referred to as being static IP

address)ordynamic IP address.

IPX

IPX (Internetwork Packet Exchange) is a networking protocol from Novell that

interconnects networks that use Novells NetWare clients and servers. IPX is a

datagram or packet protocol. IPX works at the network layer of communication

protocols and is connectionless (that is, it doesn't require that a connection be

maintained during an exchange of packets as, for example, a regular voice phone

call does).

IRQ (Interrupt Request)

A signal sent by a hardware device to the microprocessor requesting its immediate

attention. For example, each communications port has an interrupt request line for

notifying the microprocessor when data has been received or transmitted.
