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

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,

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

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

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
- 79 -
MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be sent over a network.
