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.
