Message- The message is the information (data) to be communicated. Popular forms of information include text, numbers, pictures, audio, and video.

Sender- The sender is the device that sends the data message. It can be a computer, workstation, telephone handset, video camera. The sender encodes the message.

Receiver- The receiver is the device that receives the message. It can be a computer, workstation, telephone handset, television. The receiver decodes the message

Transmission medium- The transmission medium is the physical path by which a message travels from sender to receiver, examples twisted-pair wire, coaxial cable, fiber-optic cable, and radio waves.

Protocol- A protocol is a set of rules that govern data communications. It represents an agreement between the communicating devices. Without a protocol, two devices may be connected but not communicating.
