Data Communications refers to the transmission of digital data between two or more computers. A computer network or data network is a telecommunications network that allows computers to exchange data. The physical connection between networked computing devices is established using either cables media or wireless media. The best-known computer network is the Internet.
Data Communications are said to be local if communicating devices are in the same building or in a similarly restricted geographical area.
A Data Communication system can collect data from remote locations through data transmission circuits, and then output processed results to remote locations. The different data communication techniques which are presently in widespread use, evolved gradually, either to improve the data communications techniques already existing or to replace the same with better options and features.
Communication is the process of sharing a message. A conversation between two people is an example of communication.
The performance of a Data Communications system depends on four fundamental characteristics:
A Data Communication system has the following features:
A protocol performs the following functions:
There are many benefits of Data communications some of them are:
Data Communication allows us to relay information between two or more devices.
Data Communication makes the world a global village, which means that we are all connected to each other.
Data Communications make it easy for us to carry out mundane tasks that were hard to do before easily like messaging someone over a distance.
