1. Computer: Computers that process information and are interconnected by the network 2. Network Interface: Each computer on the network contains a network interface device called a network interface card (NIC). 3. A Connection medium: The connection medium for linking network components can be a telephone wire, Coaxial cable or radio signal in the case of cell phone and wireless local area networks. 4.

Client/Server computing: Client/server computing is a distributed computing model in which much of the processing power is located within small, inexpensive client computers. Distributed computing model Largest implementation of client/server computing 2. Packet Switching: In packet-switched networks, messages are first broken down into small bundles of data called packets. Packet switching makes more efficient use of the communications capacity of a network. Packet switching more efficient use of network’s communications capacity 3. TCP/IP and Connectivity: TCP/IP is the communications protocol used by the Internet and all Internet devices. TCP/IP provides for breaking up digital messages into packets, routing them to the proper addresses, and then reassembling them into coherent messages.
