Communication Data communication, one computer (the sender or transmitter) transmits data to another computer(receiver) over a communication channel or communication link.

Networks LAN – Local Area Network MAN - A metropolitan area network (MAN) is a computer network that usually spans a city or a large campus. A MAN usually interconnects a number of LANs. WAN - A Wide Area Network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using private or public network transports.
