NIC -

>Network interface card- Gives network services to computer. Every computer  must have nic to communicate wth other computers.

HUB -

>Used to group the devices called as Multi port repeater.

SWITCH -

>Used to group the devices . Faster than Hub.

ROUTER -

>Used to communicate between different networks.
