The Home Networking
Jargon Buster
Broadband
Broadband is a new technology replacing narrowband or dial up Internet services across the UK. It is
commonly used to represent data speeds of over 500kbit/s through your phone line and is often referred
to as ‘high speed Internet access’. BT’s leading Broadband technology is Digital Subscriber Line (DSL,
also known as ADSL). With it you can get fast downloads from the Internet at speeds between 512kbit/s
and 2Mbit/s.
Modem
A modem converts analogue signals to digital signals so that data can be carried along a phone line.
Networking
Networking is the linking together of a number of computers so that you can transfer files between them,
share printers or play games – plus share one Broadband Internet connection.
Router
A device that creates a home network by allowing multiple PCs access to a single Broadband connection.
It automatically chooses the best route for the data your computer is sending or receiving.
Broadband Modem Router
A Broadband modem router is a combination of a modem and router that forms the basis of a home
network. The modem allows you to plug the network straight into your Broadband connection, the router
enables sharing of Broadband across many computers. The BT Voyager 2100 ADSL Router contains both,
meaning you only need to add adapters to your PCs to create a wireless network.
Wireless
A ‘wireless’ communications environment gives you the freedom to move around your home or office and
communicate at the same time without any wires from your phone or computer – for example –
back to the phone socket or network point.
802.11g technology
See WiFi.
WiFi
Short for ‘wireless fidelity’ with analogy to the familiar term ‘hi-fi’ or high fidelity. It is the popular term
for wireless connectivity which is technically known as ‘IEEE 802.11b’ and ‘IEEE 802.11g’. 802.11g is a
newer enhanced standard which carries data at speeds of up to 54mbps, 5 times faster than 802.11b.
Ethernet
The standard type of cable for connecting computers and other Ethernet-enabled equipment
(eg, printers) to a network.
WEP (Wired Equivalent Privacy) and WPA (WiFi Protected Access)
Two similar security protocols that are designed to give a wireless network a similar level of security and
privacy to a wired network. It does this by encrypting the data that’s carried over the radio waves from one
PC or laptop to another so helping to protect it from access and/or tampering by unauthorised individuals.
Firewall
A program that forms a barrier between a home or a company network and the outside world and so
protects it against infiltration and sabotage that could come via the Internet.
Mbps
Stands for megabits per second and is a measure of the speed at which data is
transmitted over a network.
