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
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
MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be
sent over a network. Messages larger than the MTU are divided into smaller
packets.
NAT
NAT (Network Address Translation - also known as IP masquerading) enables an
organization to present itself to the Internet with one address. NAT converts the
address of each LAN node into one IP address for the Internet (and vice versa).
