Which type of functions are performed by Data Transmission Software or Protocol?

We know computers send and receive data across communication links. We use data communication software for it. The procedure of data transmission in the form of software is known as Protocol. The data transmission software or protocols perform the following functions for transmission of data.

• Data Sequencing:- We break a large message into small and fixed size of packets for error free data transmission. 

• Data Routing:- In data routing we search the most efficient route for sending data between source and destination.

• Flow Control:- It makes the flow between fast sender and slow receiver for regulating the process of sending data. 

• Error Control:- It is the main function for communication software for error detecting and recovering it.
