DHCP

Dynamic

DHCP automates address assignment and management. When

 

Host

a computer connects to the LAN, DHCP assigns it an IP address

 

Configuratio

from a shared pool of IP addresses; after a specified time limit,

 

n Protocol

DHCP returns the address to the pool.

 

DHCP server

Dynamic

A DHCP server is a computer that is responsible for assigning IP

 

Host

addresses to the computers on a LAN. See DHCP.

DNS

Domain

The DNS maps domain names into IP addresses. DNS

 

Name

information is distributed hierarchically throughout the Internet

 

System

among computers called DNS servers. For example,

 

 

www.yahoo.com is the domain name associated with IP

 

 

address 216.115.108.243. When you start to access a web site,

 

 

a DNS server looks up the requested domain name to find its

 

 

corresponding IP address. If the DNS server cannot find the IP

 

 

address, it communicates with higher-level DNS servers to

 

 

determine the IP address. See also domain name.

domain

 

A domain name is a user-friendly name used in place of its

name

 

associated IP address. Domain names must be unique; their

 

 

assignment is controlled by the Internet Corporation for

 

 

Assigned Names and Numbers (ICANN). A domain name is a

 

 

key element of a URL, which identifies a specific file at a web

 

 

site. See also DNS.

 

download

 

To transfer data in the downstream direction, i.e. from the

 

 

Internet to the user.

 

DSL

Digital

A technology that allows both digital data and analog voice

 

Subscriber

signals to travel over existing copper telephone lines.

 

Line

 

 

Ethernet

 

The most commonly installed computer network technology,

 

 

usually using twisted pair wiring. Ethernet data rates are 10

 

 

Mbps and 100 Mbps. See also 10BASE-T, 100BASE-T, and

 

 

twisted pair.

 

firewall

 

A firewall is a method for protecting your computer or LAN from

 

 

attacks and other unwelcome or malicious accesses from the

 

 

outside (i.e. the Internet). Unauthorized users may attempt to

 

 

attack your network in order to prevent you or others on your

 

 

LAN from using.

 

 

 

You can protect your network by blocking certain types of IP

 

 

traffic commonly used by ‘hackers’ to transport attacks from the

 

 

Internet to your LAN (incoming traffic). Similarly, you can restrict

 

 

the types of IP traffic sent from your network to the Internet

 

 

(outgoing traffic). Some firewall protection can be provided by

 

 

packet filtering and Network Address Translation services.

FTP

File Transfer

A program used to transfer files between computers connected

 

Protocol

to the Internet. Common uses include uploading new or updated

 

 

files to a web server, and downloading files from a web server.

Gbps

 

Abbreviation for Gigabits (“GIG-uh-bits”) per second, or one

 

 

billion bits per second. Internet data rates are often expressed in

 

 

Gbps.
