What is the purpose of protocols in data communications?

  • specifying the bandwidth of the channel or medium for each type of communication
  • providing the rules required for a specific type of communication to occur
  • specifying the device operating systems that will support the communication
  • dictating the content of the message sent during communication
Explanation & Hint:

Protocols provide rules that define how a message is transmitted across a network. Implementation requirements such as electronic and bandwidth details for data communication are specified by standards. Operating systems are not specified by protocols, but will implement protocols. Protocols determine how and when to send a message but they do not control the contents of a message.
