What are the basic components of
operating system?
Main
components of operating system are kernel and shell. Shell is a interface
between application program and kernel. Whenever application program wants some
work to be done, it contacts kernel and kernel in turn perform work with the
help of device drivers. Thus we can say kernel is an interface between hardware
and shell.
Kernel
uses device drivers to control microcontroller card of peripheral device and in
turn work in being accompanied.
Application
program-> [shell-> kernel-> device driver-> controller card->
physical hardware]
Task of
kernel are:
§ enhanced machine or
extended machine
§ resource manager
§ library providing a range
of system oriented commands.
