The document defines an operating system as a group of programs that control a computer's processing, loading and storage of applications and data transfer. It acts as an interface between the user and hardware, managing the flow of software and data. Operating systems like Windows, Linux, and OS X allow users to run programs without coding knowledge and make computers easier to use. They provide advantages like multi-tasking capabilities but no disadvantages, as computers require an operating system to function.

2. MEANING
 operating system tells the computer how to perform
the function of loading, storing and executing an
application and how to transfer data.

3.  operating system consists a group of programs, which
control the processing operation of a computer.
 computer cannot run and cannot control the operation
of the computer’s activities.
 regulates the functioning of all input and output devices.
 It acts as the interface between the user and the
hardware.
 It manages the flow, entry, and display of software and
data to and from each part of the computer system.

5. Advantage of operating
system in computer:
 It helps us to use our computer without any knowledge
of coding
 Operating system acts as a layer between hardware and
program we use (Ms Word and so) so its advantage is
that it makes our computer work.
 get our job done easily and fast
 every business needs a new Operating System. Even
the World needs a New Operating System. It Is What
Strategic Innovation is all about. The Future is not
only close, it is already here.

6. Disadvantage of operating
system in computer:
 There are no disadvantages to an operating system,
being that without an operating system, a computer
would not be able to function, at least where it would
be any more than a series of static pictures.

7. OPERATING SYSTEM CHARACTERISTICS
 DOS
 Windows
 Window NT Processes data in 32 bit
chunks.
 UNIX
 Highly portable
OS/2
 single user system
 widely used with personal computers.
 Uses icons to execute programs
 Uses point-and-click method to execute
programs
 Applications appear in window on the
monitor
 Have multi-task and multi-processing
capabilities.
 Power interactive, multi-programming,
multi-tasking, multi-user, operating
system
 This 32-bit operating system support
multi-tasking, making it faster than DOS

8. Conclusion
 computer devices now a day are very important. Through the advance of
science and technology it helps people to do their work at a faster rate.
Operating system is one of the most important devices that install in
computer to make it running. Different version of computer is needed
different operating system to install. Operating system, applications,
input/output storage, working storage, unused storage are classified as
the main memory. It is really blessing for the people through the
introducing of computer.
