Question

A CPU has two different modes: user mode and kernel mode. The CPU switches between the two modes depending on what type of code is running on the CPU. When the CPU is in kernel mode, the CPU is prevented from accessing areas of memory that are not owned by the current process.

a) True

b) False

Answer 1

a) True

When the CPU is in kernel mode, the CPU is prevented from accessing areas of memory that are not owned by the current process. This is because the kernel is responsible for managing and protecting the CPU's resources and data, so the CPU may not be allowed to access areas owned by other processes when it is in kernel mode.
