protocol

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.

    From a user's point of view, the only interesting aspect about protocols is that your computer or device must support the right ones if you want to communicate with other computers. The protocol can be implemented either in hardware or in software.
