What are the components of a data communication?

Answer 1

components of data communication are as follow:

transmitter or receiver of data: this may be terminals,computer and mainframe etc.

medium:it is the medium though which the data is being transmitted.These are cabling,radio frequency,microwave, fiber optics,infrared,wireless etc.

receiver:as it name implies,it is the device,which receives the data transmitted,these are printers, terminals,mainframs,computers.cell phone etc.

Answer 2

The basic elements of a data communication system is: 1: signal converter, 2: computer, 3: receiver, 4: sender, and 5: transmission medium. An example of a data communication system is a radio communication system.

Answer 3

Message :

This is most useful asset of a data communication system. The message simply refers to data or piece of information which is to be communicated. A message could be in any form, it may be in form of a text file, an audio file, a video file, etc.

Sender :

To transfer message from source to destination, someone must be there who will play role of a source. Sender plays part of a source in data communication system. It is simple a device that sends data message. The device could be in form of a computer, mobile, telephone, laptop, video camera, or a workstation, etc.

Receiver :

It is destination where finally message sent by source has arrived. It is a device that receives message. Same as sender, receiver can also be in form of a computer, telephone mobile, workstation, etc.

Transmission Medium :

In entire process of data communication, there must be something which could act as a bridge between sender and receiver, Transmission medium plays that part. It is physical path by which data or message travels from sender to receiver. Transmission medium could be guided (with wires) or unguided (without wires), for example, twisted pair cable, fiber optic cable, radio waves, microwaves, etc.

Protocol :

To govern data communications, various sets of rules had been already designed by the designers of the communication systems, which represent a kind of agreement between communicating devices. These are defined as protocol. In simple terms, the protocol is a set of rules that govern data communication. If two different devices are connected but there is no protocol among them, there would not be any kind of communication between those two devices. Thus the protocol is necessary for data communication to take place.

A typical example of a data communication system is sending an e-mail. The user which send email act as sender, message is data which user wants to send, receiver is one whom user wants to send message, there are many protocols involved in this entire process, one of them is Simple Mail Transfer Protocol (SMTP), both sender and receiver must have an internet connection which uses a wireless medium to send and receive email.
