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

In computer communication, what is the purpose of message encoding?

• to interpret information
• to break large messages into smaller frames
• to convert information to the appropriate form for transmission
• to negotiate correct timing for successful communication

What is the purpose of protocols in data communications?

• dictating the content of the message sent during communication
• 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

What is the general term that is used to describe a piece of data at any layer of a networking model?

• packet
