what is mean by kernal?

Answer

manoj urs was a gud doubt ie the difference b/w kernal nd os
my ans to this is
An operating system, also known as an OS, is the software
that makes a computer usable. The kernel is merely the
"core" or lowest level of an operating system. The kernel
provides numerous callable routines that allow other
software to access files, display text and graphics, get
input from a keyboard or mouse, and other such capabilities.

The operating systems that we come across today, generally
have many features which are not the necessary features to
make a system work. But these features are required to make
the interaction with the system easier. Such features
include graphical interface, file management, process
management, shell, etc. These features rely on the core part
of the OS (called as kernel) to run and provide interface to
the user or other application programs. It is to be realized
that these features are inevitable, and only a kernel alone
is of no use to the user.
