1. Wireless networks are another means by which data can be exchanged between a computer and a network, including the internet. A wireless network is any network servicing computers or other devices (e.g. mobile phones), in which the connections do not use cables of any kind. Wireless communication usually uses radio waves, but infrared communication is also used.

2. In wireless networking all devices using the network need to have a wireless network interface card through which they gain access to the network. The card is used to transmit data across the network and to receive incoming data from the network.

3. The network itself will contain routers and network access points

   • Wireless networks have many advantages – probably the most important is mobility; people are no longer tied to desks and wires.
     • data – Any kind of information that has been formatted in a specifi c way. Different types of data include audio, video, images and monitoring signals, as well as text.

4. devices/components – Used as a generic term to mean computers, peripheral hardware, mobile telephones, manufacturing plant, environment monitors and many other thing

5. Unshielded twisted pair (UTP) cables are basic pairs of cables twisted together. Shielded twisted pair (STP) cables are similar but have a foil shielding.

6. Solid wire core separated from a copper-braided outer cable by a plastic insulation sheath. The inner cable transmits the data and the outer cable connects to earth.

7. Glass or plastic cables which use total internal reflection of light to transmit data. Normally uses LED or laser visible light, although infrared has also been used.

8. The cable networks use fibre from their source to the distribution panels in the street. From there they use coaxial cable to individual households.
