8 Which term describes the process of adding headers to data as it moves down OSI layers?

• division
• encoding
• separation
• Segmentation*
• Encapsulation+
  

9 What is one advantage of defining network communication by the seven layers of the OSI model?

• It increases the bandwidth of a network.
• It makes networking easier to learn and understand.*
• It eliminates many protocol restrictions.
• It increases the throughput of a network.
• It reduces the need for testing network connectivity.

10 Refer to the following list. Choose the correct order of data encapsulation when a device sends information.
