What is Data Compression?

Communication means a “to share”. Data communication is actually sharing of information, knowledge and important data.

For example: we want to send a file to our Boss. We prepare it and deliver it to Boss by hand or by post or by a peon, this is called data communication. In similar way we can send it through computer (via email) considering that we are working on modern technology.

So data communication is a sharing, distribution of information where some person will send (sender entity), someone will receive (receiver entity) and there will be the medium (wire, air, peon) who transfer this information.

This is important because without communicating we are not able to  pass our information,problem or message to others,which is necessary to solve that problem or present our point of view etc.
