DHCP is a client-server networking protocol. Most organizations use DHCP. A DHCP
server provides configuration parameters specific to the DHCP client host requesting,
generally, information required by the host to participate on the Internet network. DHCP
also provides a mechanism for allocation of IP addresses to hosts.
DNS
Domain Name System
A hierarchical way of tracking domain names and their addresses, devised in the
mid-1980s. The DNS database does not rely on one file or even one server, but rather is
distributed over several key computers across the Internet to prevent catastrophic failure
if one or a few computers crash. DNS is a TCP/IP service that belongs to the Application
layer of the OSI model.
Ethernet
A local area network (LAN) architecture developed by Xerox Corporation in
cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and
supports data transfer rates of 10 Mbit/s. The Ethernet specification serves as the basis
for the IEEE 802.3 standard, which specifies the physical and lower software layers.
Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of
the most widely implemented LAN standards.
