Question:
What is done to an IP packet before it is transmitted over the physical medium?

  • It is tagged with information guaranteeing reliable delivery.
  • It is segmented into smaller individual pieces.
  • It is encapsulated into a TCP segment.
  • It is encapsulated in a Layer 2 frame.

Explanation: When messages are sent on a network, the encapsulation process works from the top of the OSI or TCP/IP model to the bottom. At each layer of the model, the upper layer information is encapsulated into the data field of the next protocol. For example, before an IP packet can be sent, it is encapsulated in a data link frame at Layer 2 so that it can be sent over the physical medium.
