Data communication is the flow of electronic data among two nodes (computers and other devices) through communication media.
In order to manage the communication, the nodes must be part of communication system and linked with each other via some media like cables or microwave. Furthermore the data communication software is used to transfer data from one node to another.
The communication system is governed by three fundamental principles that include deliver, accuracy, and timeliness.
1. Delivery: The system must carry data to the correct end or destination. Data must be received by the correct recipient (device/user).
2. Accuracy: The system must deliver the data with accuracy. The altered or incomplete data is unusable, therefore it should be accurate as per sending format.
3. Timeliness: The system must deliver data in time. Late delivery of data may not be effective; therefore time delivery should be achieved.
