broadband

High-speed telecommunication over a wide range of frequencies, typically 256 Kbps or faster. Broadband enables more information to

 

be transmitted in less time. The most common broadband service types available to home and small-office users are cable modem or

 

DSL. Both cable modem and DSL are much faster than a traditional dial-up Internet connection.

Domain Name The DNS is the Internet system for converting domain names to IP addresses. A DNS server contains a table matching domain names

System (DNS) such as Internetname.com to IP addresses such as 192.169.9.1. When you access the world-wide web, a DNS server translates the URL displayed on the browser to the destination website IP address. The DNS lookup table is a distributed Internet database; no one DNS server lists all domain name to IP address matches.

download downstream

Dynamic Host Configuration Protocol (DHCP)

To copy a file from one computer to another. You can use the Internet to download files from a server to your home computer. In a cable data or DSL network, downstream describes the direction of data received by your computer from the Internet.

A DHCP server dynamically assigns IP addresses to client hosts on an IP network. DHCP eliminates the need to manually assign static IP addresses by “leasing” an IP address and subnet mask to each client. It enables the automatic reuse of unused IP addresses.
