Data communication may be a process by which information (in the form of text, volumes, images, sound and video) is transmitted from one device to another. This can be done with the help of different sign mediums such as  » cable  » and wifi media.

Data Communication Systems:

Message, Sender and Device are the main components within a data communication system. Sales message is the info which the sender wants to copy to the recipient, the device can be a computer, telephone mobile or workstation etc .

Process: A process is a pair of rules which will govern the exchange of data between the two devices. These guidelines make sure that the info is fully understood by equally the devices and perhaps they are able to communicate with each other without any misunderstandings.

Data Tranny:

Basically, info is sent in two modalities – dramón and parallel. In serial method, data is transmitted one bit by a time along a cable tv, as revealed in Amount 4. twenty. Similarly, in parallel mode, all the components of a word are simultaneously sent along a pair of cables.

Mistakes in data transmission:

An individual of this major difficulties with the transfer of digital data is that it is quite difficult to transmit it effectively over a very long distance. This is because there are a lot of electrical power distortions and noises that may cause mistakes in the tranny of the data.

To triumph over these concerns, engineers have developed data transmission protocols to control and address the errors that are created during info transmission. These protocols likewise ensure that the received info is sent to the meant individual. These protocols are often called Data Transfer Protocols (DTP).
