Question

Which can increase context switch time in memory management?

Answer 1

Introduction

In the last lecture, we saw the reason for user mode and kernel mode, and the three ways in which a user-mode program can fall into kernel mode.

We also saw that kernel mode protects peripheral devices from direct access by user-mode programs.

In the last hardware lecture, we are going to see how memory is protected so as to stop programs from looking at each other's memory and the operating system's memory.

We will also see how the CPU can be switched from one running program to another.

Answer 2

According to studies that have been conducted on keNel mode is very useful for user mode  in where by the user mode usually falls under the kenel mode. Kenel mode usually acts a protection for the peripheral devices from accessing direct access by the programs that are entailed in user mode program.  the memory is usually prevented from accessing other programs in other memories where by one memory cannot looking to another memory programs that are stored i another memory.
