Wired Network –

In the networking world, “Wired” as the name suggests refers to any physical medium connected through wires and cables. The wires/cables can be copper wire, twisted pair or even fibre optic. Wired connectivity is responsible for providing high security with high Bandwidth provisioned for each user.

In fact, Wired connectivity is considered highly reliable and incurs very low delay, unlike Wireless connectivity.
