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

ADSL – Asymmetric Digital Subscriber Line, is the most popular form of internet connection in the UK

IP Transit – internet transit hosted by an ISP.

Atom – similar to RSS but is newer and offers a greater range of facilities. Still in development, but catching on. The technology is based on RSS.

Bandwidth – the total of information you can send through a connection. Bandwidth is generally measured in megabits per second.

Blog – similar to an online journal where a person or society may publish its thoughts or opinions, but can also publish facts. Often updated at least once a week and ordinarily roughly daily and is arranged chronologically in order.

Broadband refers to a connection which has more bandwidth than a modem, and tends to be a very generic term with no specific speed attached to it, but will always mean a connection to the internet rather than LAN connection.

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 – distributes IP addresses to clients on a network dynamically.

DNS – domain name system is 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, separating the name, and at the end a tld or domain ending such as .com.

Ethernet – a standard networking method via a LAN, with varying speeds.

Firewall – protection from malicious network traffic.

FTP – file transfer protocol a common method transferring files around the internet quickly and easily.

A host is a computer or client on a network that provides services to other computers or clients on the same network.

HTTP or HyperText Transfer Protocol allows hypertext files to be transfered to and from and across the internet. HTTP is the most important protocol used in the World Wide Web (www)

IMAP is gradually replacing POP as the main protocol used by email clients in communicating with email servers. Using IMAP, an email client program can not only retrieve email but can also manipulate message 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, this 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 the next generation of IPv4 with over a sextillion addresses (theoretically 2128) deployment of IPv6 is slow currently but will get great when more and more devices support it.

LAN Local area network, which is normally defined as being within the same building or floor of a building.

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