INTRODUCTION TO OPERATING SYSTEM
An operating system is a course that is very important as far as
computer science is
concerned and also electronic students you may have this subject in
your course so it is
equally important and this subject it consists mainly of theory as well
as problems so we
will first see the theory and also we will be solving the problems related
to this subject. IO
devices means the input/output devices. These are the devices that
you use for either
giving input to your system or for getting output out of your system. On
top of this
operating system we have the system or the application programs.
There are two kinds of software 's we have which is system software
and application software. Imagine that there is no operating system
over here we just have this user and the application programs and then
the computer hardware. If you wants to write a document or if you want
to type something into Microsoft Word then he have to tell the
computer how where that he wants to do it now how can he do it since
there is. It is such a tedious thing and it is very difficult to perform even
the simplest of tasks so in order to avoid this or to overcome this
problem what we have is an operating system.
An operating system is a program that manages the computer
hardware. It acts as an
intermediary between the user and the hardware thus making the
process of
computation and the usage of computers seamless and very easy for
the users so that is
the main fun of an operating system. We will be seeing some of the
types of operating
systems that we have and also the functions of operating system and
what are the goals
that an OS needs to achieve. OS acts like an interface between the
user and hardware and
allocation of resources. OS allocates resources to different users or
different processes in
New Section 2 Page 1
, different processes in
a good manner that is the function of the operating system and then it
does the
management of memory secure etc so I told you even when we were
typing this word
processor we have to first load it into the main memory then after
typing it has to be
saved into secondary memory or the hard disk.
The first goal of operating system is to provide convenience and then
the second point is efficiency. Operating system by taking care of all
these allocations of resources and management of memory and
everything it provides you an efficient usage of your system. Many
operating systems are designed mainly for convenience. Some are
designed for both convenience as well as efficiency.
Basics of OS (Computer System Operation)

Some basic knowledge of the structure of computer system is required
to understand
how operating systems work so by studying about this will provide you
a base for
understanding operating system so instead of diving into how
operating system works we
should have a base about this so that it will help us to understand in a
clearer way about
operating system. After studying this you will not feel completely blank
but you will have
a proper idea of why we are doing this or why certain thing is working
in that way. Each of
these hardware 's or devices are connected to a controller and this
controller is
responsible for the way these devices work so here we have device
controllers and each
of these controllers or adapters they are in control of a specific kind of
device as it is
shown here. The CPU and the device controllers can execute
concurrently competing for
memory cycles. Your main memory is like your RAM random access
memory that you
