The size of the segment register is:
Correct answer: C. 4-bytes
- A. 1-byte
- B. 2-bytes
- C. 4-bytes
- D. 8-bytes
Explanation
This is the most common size for a segment register today. A 4-byte register can hold a 32-bit address, which allows for a larger memory addressing space. Segment registers are used in segmentation, a memory management technique that divides memory into segments. The size of a segment register determines the maximum size of a segment that can be addressed. Since 4 bytes is a common size for segment registers, it provides a good balance between manageability and addressing range for memory segmentation.
