Physical methods of transferring data
Optical Fibre – used for very fast connections between switches in a network and to bring broadband to buildings and business premises
These are very fast connections but not good for places the cable might be moved like in a workstation.
Unshielded twisted pair (UTP) – used widely to connect computers and printers to switches in LANs with CAT6 or CAT5 cabling. UTP is a great all-rounder for cables LANs, but is poor at very high speeds.
Coaxial cables (coax) – Used to connect homes to optical broadband systems.
This is good for short distances, but poor for longer stretches.
