An agreed-upon format for transmitting data between two devices. The protocol determines the following:

  • the type of error checking to be used
  • how the sending device will indicate that it has finished sending a message
    • how the receiving device will indicate that it has received a message

    There are a variety of standard protocols from which programmerscan choose. Each has particular advantages and disadvantages; for example, some are simpler than others, some are more reliable, and some are faster.
