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.
