When you install RedHat what is the kernel mode ? What is
kernel compilation / upgrade ?

Answer Posted / 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.
