1. What is the process of dividing a large data stream into smaller pieces prior to transmission?
- sequencing
- duplexing
- multiplexing
- segmentation
Explanation: Segmentation is the process of dividing a large data stream into smaller pieces which are then transmitted to the receiver.
2. What is the PDU associated with the transport layer?
- segment
- packet
- bits
- frame
Explanation: The transport layer PDU is known as a segment.
3. Which protocol stack layer encapsulates data into frames?
- data link
- transport
- network
- application
Explanation: The data link layer encapsulates data into a frame.
4. What is the name of the process of adding protocol information to data as it moves down the protocol stack?
- de-encapsulation
- sequencing
- segmentation
- encapsulation
Explanation: As data moves down the protocol stack, protocol data is added to the original data. This process is known as encapsulation.
