Data protocol is a standard set of regulations and requirements that allow two electronic items to connect to and exchange information with one another across a network. 

Protocols regulate data transmission among devices as well as within a network of linked devices through both error control and specifying which data compression method to use. In particular, protocols decide the following:

  • The method of error checking
  • How to compact data (if required)
  • How the transmitting device signals that it has concluded sending data
  • How the receiving device signals that it has completed receiving data
