Question

a) Local
b) Universal
c) Global
d) Public

Answer 1

Global replacement allows a process to select a replacement frame from the set of all frames, even if the frame is currently allocated to some other process.

Step-by-step explanation:

The correct answer is c) Global.

Global replacement allows a process to select a replacement frame from the set of all frames, even if the frame is currently allocated to some other process. This means that a process can replace a frame that is being used by another process.

For example, imagine a computer system with multiple processes running simultaneously. If one process needs more memory and there are no free frames available, it can use global replacement to select a frame that is currently being used by another process, and replace its contents with its own data.
