  • 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.
