Network Communications

Communication Protocols

It is very interesting to know that how computers send and receive the information across the communication links. Computers do this job by the help of data communication software. It is software that enables computers to communicate with each other. The data transmission software tells the devices and computers how to send information to the other computers. The software that is used for the data transmission is known as protocol. The data transmission software or protocols perform the following basic functions:


1. Data sequencing: A long message is broken up into the smaller packets of fixed size for the error free transmission.
2. Data Routing: In the data routing process the most efficient route is to find to send the data from the source to the destination.
3. Flow control: The flow control regulates the process of sending data between fast sender and slow receiver.
4. Error Control: Error detection and recovery is the most important factor of the data transmission software (protocols). It ensures the error free transmission of the data.
