D H C P ( D y n a m i c H o s t C o n f i g u r a t i o n P r o t o c o l )
automates address assignment and management. When a c omputer connects to the LAN,
DHC P assigns it an IP address from a s hared pool of IP addresses; after a specified time limit,
DHC P returns the address to the pool.
E t h e r n e t
The most commonly installed computer network technology, usually using twisted pair wiring.
Ethernet data rates are 10 Mbps and 100 Mbps.

F T P ( F i l e T r a n s f e r P r o t o c o l )
A program used to transfer files between computers connected to the Internet. C ommon uses

network ID
that
identifies the particular network the host belongs to, and a
host ID
uniquely identifying the host
