What are two benefits of using a layered network model? (Choose two.)

• it prevents technology in one layer from affecting other layers

• its speeds up packet delivery

• it ensures a device at one layer can function at the next higher layer

• It assists in protocol design

What is the purpose of protocols in data communications?

• specifying the bandwidth of the channel or medium for each type of communication

• specifying the device operating systems that will support the communication

• dictating the content of the message sent during communication

• providing the rules required for a specific type of communication to occur
