Internet Network Terminology Explained

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 net connection in the UK

IPTransit – an internet connection provided by a transit provider.

Atom – is like traditional RSS, but with more options. It is still being developed but is becoming more common place. The technology is based on RSS.

Bandwidth – refers to data transfer from one location to another. Bandwidth is generally measured in megabits per second.

Blog – similar to an online diary where a person or society may publish its thoughts or opinions, but can also publish facts. Most bloggers update once a week, where blogs are chronologically arranged.

A generic high speed internet connection – faster than a standard modem.

Co-location – where an ISP hosted an individual or companies server or hardware on their behalf.

DHCP – Dynamic Host Configuration Protocol distributes IP addresses dynamically to clients on a network.

DNS – Domain Name System is used to translate domain names into IP address, with a DNS server providing the translation service.

Domain name – all websites have a unique domain name. Domain names have three sections to them- in the center 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 – can be either hardware or software based to prevent access to another network for security reasons.

FTP or File Transfer Protocol – is a method used to transfer files to and from the internet.

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

HTTP – HyperText Transfer Protocol is used for moving hypertext files around the internet. HTTP is best known for loading websites.

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 content stored on the server, without having to actually retrieve the messages. So messages can be deleted, have their status changed, multiple mail boxes can be managed, etc.

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 cover it.

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

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

Where would a company find these services? IP transit provider would be able to provided these hosting services for a company or individual.
