Answer / fuzail usmani
Kernel mode, also referred to as system mode, is one of the
two distinct modes of operation of the CPU in Linux. The
other is user mode, a non-privileged mode for user programs,
that is, for everything other than the kernel.
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. The kernel
is trusted software, but all other programs are considered
untrusted software. Thus, all user mode software must
request use of the kernel by means of a system call in order
to perform privileged instructions, such as process creation
or input/output.

Answer / susheel narayan singh
when you install redhat at that time you can switch into
terminals from ctrl+alt+f1 to ctrl+alt+f7
each terminal show different message.
but when you will go ctrl+alt+f4 then it is kernel mode
because it show kernel messages including detected hardware
and drivers.

Answer / ashish
I guess the Kernel mode will be kernel itself and the user
processes will not be able to use the resources that the
kernel is using. This is done to protect the kernel from
user programs.
Kernel compilation is installing a new kernel or adding
custom modules to the same kernel.
Kernel upgradation is upgrading it to a different version
altogether.
