The first major model for communication was introduced by Claude Shannon and Warren Weaver for Bell Laboratories in 1949  The original model was designed to mirror the functioning of radio and telephone technologies. Their initial model consisted of three primary parts: sender, channel, and receiver. The sender was the part of a telephone a person spoke into, the channel was the telephone itself, and the receiver was the part of the phone where one could hear the other person. Shannon and Weaver also recognized that often there is static that interferes with one listening to a telephone conversation , which they deemed noise.
Communication using electronic media known as electronic communication. Such communication allows transmission of message or information using computer systems, fax machine, e-mail, title or video conferencing and satellite network. People can easily share conversation, picture, image, sound, graphics, maps, interactive software and thousands of things for the development of electronic communication. Due to electronic technology, jobs, working locations and cultures are changing, and therefore people can easily access to worldwide communication without any physical movement.
