• Allcast

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

• To convert information to the appropriate form for transmission

• To interpret information

• To break large messages into smaller frames

• To negotiate correct timing for successful communication

Which message delivery option is used when all devices need to receive the same message simultaneously?

• Duplex

• Unicast

• Multicast

• Broadcast

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

• It assists in protocol design.

  
  

• It speeds up packet delivery.

• It prevents designers from creating their own model.

• It prevents technology in one layer from affecting other layers.

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

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

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

• Dictating the content of the message sent during communication

Which logical address is used for delivery of data to a remote network?

• Destination MAC address

• Destination IP address

• Destination port number

• Source MAC address

• Source IP address

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

• 
  Frame

• Packet

• Protocol data unit

• Segment

Which two protocols function at the internet layer? (Choose two.)

• POP

• BOOTP

• ICMP

• IP

• PPP

Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices?

• Application

• Presentation

• Session

• Transport
