A CPU has 2 modes

1> Privileged mode

In this mode, you can access all the areas of memory and make changes in any register. So basically you have unrestricted access to Privileged mode.

2> User mode

In this mode, you get to access the memory in a limited manner and also you get to make no changes in the memory registers.
