·         -TCP/IP is the standard protocol for network communication in LAN or WAN

·         -All the devices and applications have to follow to same protocols to make network communication system.

Communication Devices

·         -Communication devices that are used in LAN/MAN/WAN and wireless networking.

·         The most important devices

o   Router

o   Switch

o   Hub

o   Modem

o   NIC adapter

o   Access points

o   Broadband router

o   Communication cables

·         -Hub/Switch is a centralized device in a LAN and all the computers connect with the Hub/Switch. In case of failure of Hub/Switch the whole communication stops.

·         -Router routes the traffic to the destination based on the IP address of the source and destination computer.

·         -The router chooses the best short possible path for data to be sent to its destination.

·         -Wireless routers and access points are used in the wireless networking.
