a server to dynamically assign IP addresses from a predefined list
and limit their time of use so that they can be reassigned. Without
DHCP, an IT Manager would have to manually enter in all the IP
addresses of all the computers on the network. When DHCP is
used, whenever a computer logs onto the network, it automatically
gets an IP address assigned to it.

network, or Plain Old Telephone Service (POTS).
Diversity antenna - A type of antenna system that uses two

DNS (Domain Name System, or Service, or Server). A program
that translates URLs to IP addresses by accessing a database
maintained on a collection of Internet servers. The program works
behind the scenes to facilitate surfing the Web with alpha versus
numeric addresses. A DNS server converts a name like
mywebsite.com to a series of numbers like 107.22.55.26. Every
website has its own specific IP address on the Internet.
