Difference Between Kernel mode and User mode:, Criteria, , Kernel-mode vs User, mode, , Interruptions, , Modes, , Virtual address space, , Level of privilege, , Restrictions, , Kernel Mode, In kernel mode, the, program has direct and, unrestricted access to, system resources., , User Mode, In user mode, the application program, executes and starts out., , In Kernel mode, the whole, operating system might go In user mode, a single process fails if an, down if an interrupt occurs interrupt occurs., Kernel mode is also known as User mode is also known as the, the master mode, privileged unprivileged mode, restricted mode, or, mode, or system mode., slave mode., In kernel mode, all, processes share a single, virtual address space., , In kernel mode, the, applications have more, privileges as compared to, user mode., As kernel mode can, access both the user, programs as well as the, kernel programs there are, no restrictions., , In user mode, all processes get separate, virtual address space., , While in user mode the applications have, fewer privileges., , While user mode needs to access kernel, programs as it cannot directly access, them.
