Learning Aims B Methods of Data Transfer

Unshielded twisted pair is pairs of copper wires twisted together. This is the same for STP only that it is shielded 

Benefits/draw backs : interference is reduced due to twisting, cheaper than other methods, Poor at high speeds 

Glass or Plastic cables using light to transmit data

Benefits/draw back - Fast, Used over long distances, minimal interference, Expensive

Coaxial Cable 

Benefit/Draw back - Solid copper wire with thick shielding 

Reliable, Good for short distance, slow 

Uses - Used in older networks and home optical broadcast system.

wifi 

A common technology for wireless networking. It is built in as a standard in most modern devices. It needs an access point to connect to.

Uses

Connects Mobile devices to connect to (WAP) 

Blue Tooth 

Connecting mobile devices to networks

Uses 

Headsets wireless keyboards and mice
