Define Direct Attached Cable (DAC)

Twisted Pair
Most common type of cable used in network. Consists of twisted pairs of cables bundled together in a common jacket.
Each pair works as team either transmitting or receiving data.
Helps to reduce crosstalk
Define STP
Shielded Twisted Pair
UTP
Unshielded Twisted Pair
