Question

With relocation and limit registers, each logical address must be _______ the limit register.

a) Less than
b) Equal to
c) Greater than
d) None of these

Answer 1

Each logical address must be less than the limit register, as part of an operating system's memory management system to ensure a program only accesses its allocated memory space.

Step-by-step explanation:

In the context of computer operating systems that use relocation and limit registers, each logical address that is generated by a program must be less than the content of the limit register. The relocation register holds the value that the physical address must be adjusted by (relocated) to ensure that a program operates within its allocated space, while the limit register contains the range of logical addresses a process can use.

If a logical address is greater than or equal to the limit register, this typically indicates an attempt to access memory beyond the allocated range, which is generally not allowed and will cause an error, such as a segmentation fault or a program crash.
