A pair of copper cables twisted to protect the singal A type of network media that transfers electrical signals via copper medium Twisted Pair cable Coaxial cable A pair of copper cables twisted to protect the singal A copper or aluminium cable coved with a jacket that carries electrical signals.

Fiber Optic Cables A type of network media (cables) uses glass to carry the light signal. that transfers electrical signals via copper medium The fiber optic cable can carry the most data because it is not affected by outside signal or electromagnetic fields

Wireless Medium A type of network media uses radio signals to connect devices. Wifi and 4G networks uses the wireless network medium

Bandwidth Data transfers as small units through network medium as Packets. Each packet contains data in the image of 0s and 1s Number of bits that can go through the network medium is called bandwidth.

Bandwidth is measured in:
