Introduction to operating systems
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 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.
