Networking~Network Terms~Phrases~Keywords~Buzz Words~Words~Terminology Explained~Detailed~Unleashed~For Dummies

By Jenny Marcia Irwin


If networking terms puzzle you, this should hopefully explain some of the main ones.

ADSL - Asymmetric Digital Subscriber Line. A popular and prevalent internet connection for home users in the UK.

IP Transit - internet connectivity provided to a person or business.

Atom - similar to RSS but is newer and offers a greater range of facilities. Atom is still in development, but catching on. It is also an XML based specification like RSS.

Bandwidth refers to information being transfered through an internet connection. This is commonly measured in megabits per second (Mbps) or kilobits per second (Kbps).

Blog - just like an online diary. Most bloggers update once a week, where blogs are chronologically arranged.

Broadband is a generic high speed internet connection- faster than a standard modem.

Co-Location is where a server belongs to one person or company but is hosted on the internet by another company or person.

DHCP - Dynamic Host Configuration protocol distributes IP addresses dynamically to clients on a network.

DNS - Domain Name System, a mechanasim that takes a domain name and translates it into an IP address.

Domain Name - a unique name that is used to identify an internet site. Domain names have three sections to them- in the centre a dot, separing the name, and at the end a tld or domain ending such as .com.

Ethernet - a common networking method on a LAN. Several speeds are available.

Firewall- used to keep the bad guys out. Provides protection and filtering of certain traffic.

FTP - File transfer protocol, a common method transferring files around the internet quickly and easily.

Host - a client on a network that provides services to other computers or clients on that network.

HTTP or HyperText Transfer Protocol allows hypertext files to be transfered from the internet. HTTP is commonly known for loading websites.

IMAP is an email technology. Using IMAP an email client program can not only retrieve email but can also manipulate content stored on the server, without having to actually retrieve the messages. IMAP allows for greater control over email as they can be stored, emailed etc and shared between groups where POP email can't.

IPv4 - Internet Protocol version 4, is the most widely used version of the internet protocol. IPv4 has a maximum of four billion IP Numbers (technically 232) but due to the way it was designed this is actually less than that due to some inefficiencies.

IPv6 is slowly coming into play as the replacement for IPv4, allowing for a vast amount more IP addresses.

LAN - Local area network, commonly used in small organisations.

Network - when two or more computers are connected together to share resources.

Where would a company find these services? An IP Transit provider would be able to cater for most of the services above.
