Fragment Offset Unit in IP Datagram | Generated by AI
The unit of the Fragment Offset field in the fixed part of an IP datagram structure is 8 bytes (B).
Explanation:
- The Fragment Offset field indicates the position of the current fragment relative to the start of the original IP datagram.
- Since IP datagram fragments must be multiples of 8 bytes in length, the Fragment Offset is measured in units of 8 bytes.
- The value of the Fragment Offset is multiplied by 8 to get the actual offset in bytes.
Analysis of Options:
- A. 1B: Incorrect, the unit is not 1 byte.
- B. 8B: Correct, the unit is 8 bytes.
- C. 16B: Incorrect, the unit is not 16 bytes.
- D. 32B: Incorrect, the unit is not 32 bytes.
Thus, the correct answer is B.
