Q.14 Difference between Kernel Mode vs User mode in window & Linux.
Solution :-
| Feature | Kernel Mode | User Mode |
|---|---|---|
| Privilege Level | High (full access to system resources) | Low (restricted access) |
| Access to Hardware | Direct access to CPU, memory, and I/O devices | Cannot access hardware directly, requires system calls |
| Process Execution | Executes core OS functions and device drivers | Runs applications and user processes |
| Memory Access | Has access to all system memory | Restricted to allocated memory space |
| Stability & Security | Errors can crash the entire system | Errors affect only the specific application |
| Performance | High-speed execution due to direct access | Slightly slower as requests must go through the kernel |
