NIC Network Interface Card

Connecting Devices : switch ,
bridge repeaters

Bound Media :

UTP twisted pair of wires to transmit data what
:
an aluminum sheath
-
STP : twisted pair of wires w/ an aluminum sheath
↳ Bound Media Cons :
-
Attenuation : loss of signal strength over a distance
-
EMI :
nearby cables or current influences/corrupts data
-
Crosstalk nearby cables exchange data
:
Eavesdropping people can interpret data being carried due to EMI
