TCP/IP Glossary C-5
TCP/IP Glossary DHCP - Dynamic Host Configuration Protocol, a standard that
enables each client on the network to request and receive an IP
address from a DHCP server. These addresses expire after a cer-
tain time so that a pool of addresses can be shared among a
group of workstations. DHCP also allows static (permanent) IP
addresses to coexist with the dynamically assigned addresses.
DNS - Domain Name System, a method for matching a host
name to an IP address, for example: the host name www.color-
span.com translates to the IP address 204.26.120.4. A DNS server
can serve a local area network or the Internet.
Ethernet - a standard for local area network hardware and
cabling, on which networking protocols can operate.
host name - the unique name by which a computer is known to
the network, for example: www.colorspan.com.
Internet - a worldwide network that connects computer net-
works to each other.
IP address - Internet Protocol address, the address used by the
TCP/IP protocol to identify a host computer. It is usually writ-
ten as a group of decimal numbers separated by periods (exam-
ple: 204.26.120.4). The IP address can be configured statically
on the client or configured dynamically through DHCP.
network - computers that share data with each other by means
of software, cabling, and hardware.
protocol - a set of formal rules that describe how to transmit
data, especially across a network.
server - software or a computer that provides a service -- such as
file, printer or DNS services -- to other software or computers
(“clients”).
subnet - a local division of an organization's IP address that is
not visible to the Internet, allows local network administrators
to allocate IP addresses without affecting the Internet. The sub-
net is identified to TCP/IP by a number called the “subnet
mask.”
TCP/IP - Transmission Control Protocol/Internet Protocol, a
standard network protocol used in local area networks and the
Internet.
