• Switches: It connects devices on a computer network.packet switching to receive & forward data to the destination device 

• Routers: It connect networked computers to the Internet and connect multiple networks and forward packets

• Bridges: It can be used used to connect LAN Network.

• Modems: It can be used transmitted from one computer to another computer data transfer

• Hubs: It can be used to connect segments of a LAN.
