transferring large files or uploading the HTML pages for a Web site to the Web server.

Gateway

Gateways are computers that convert protocols enabling different networks, applications, and operating

systems to exchange information.

Host Name

The name given to a computer or client station that acts as a source for information on the network.

HTTP

HTTP (HyperText Transport Protocol) is the communications protocol used to connect to servers on the

World Wide Web. HTTP establishes a connection with a Web server and transmits HTML pages to client

browser (for example Windows IE). HTTP addresses all begin with the prefix 'http://' prefix (for example,

http://www.yahoo.com).

ICMP

ICMP (Internet Control Message Protocol) is a TCP/IP protocol used to send error and control messages

over the LAN (for example, it is used by the router to notify a message sender that the destination node is

not available).

IP (Internet Protocol) is the protocol in the TCP/IP communications protocol suite that contains a network

address and allows messages to be routed to a different network or subnet. However, IP does not ensure

delivery of a complete message—TCP provides the function of ensuring delivery.

IP Address

The IP (Internet Protocol) address refers to the address of a computer attached to a TCP/IP network.

Every client and server station must have a unique IP address. Clients are assigned either a permanent

address or have one dynamically assigned to them via DHCP. IP addresses are written as four sets of

numbers separated by periods (for example, 211.23.181.189).

ISP

An ISP is an organization providing Internet access service via modems, ISDN (Integrated Services

Digital Network), and private lines.

LAN

LANs (Local Area Networks) are networks that serve users within specific geographical areas, such as in

a company building. LANs are comprised of servers, workstations, a network operating system, and

communications links such as the router.

MAC Address

A MAC address is a unique serial number burned into hardware adapters, giving the adapter a unique

identification.

Metric

A number that indicates how long a packet takes to get to its destination.

MTU

- 84 -

MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be sent over a network.
