Answer / lipsa naik
Kernel mode, also referred to as system mode, is one of the
two distinct modes of operation of the CPU (central
processing unit) in Linux. The other is user mode, a non-
privileged mode for user programs. When the CPU is in
kernel mode, it is assumed to be executing trusted
software, and thus it can execute any instructions and
reference any memory addresses. all user mode software must
request use of the kernel by means of a system call in
order to perform privileged. The standard procedure to
change from user mode to kernel mode is to call the
software interrupt 0x80. All processes begin execution in
user mode, and they switch to kernel mode only when
obtaining a service provided by the kernel. This change in
mode is termed a mode switch.

the system stability and system can be resumed.

failue (System Failure)
