Which of the following statement is correct?
A) Base register holds the size of a process.
B) Limit register holds the size of a process.

Question

Quizplus · Accepted Answer

The limit register holds the maximum legal address that a program can access, while the base register holds the smallest legal address. Therefore, option B is correct. Option A is incorrect because the base register does not hold the size of the process, but rather the starting address of the process. Option C is incorrect because base and limit registers are typically loaded automatically by the operating system, not by standard load instructions. Option D is incorrect because attempting to access memory beyond the limit register's value will result in a trap, not attempting to access memory beyond the base register's value.
