What is Operating System ?
Computer
takes the help of various devices and programs to perform its work. There is
also a separate and special computer program to handle these devices and
programs.

| What is Operating System ? |
This special and master program is known as Operating System. Which breathes life into the computer system. Without this program the computer is like a dead box.
Therefore, all computer users should have basic knowledge about this very important computer program. Only then, it will help in using the computer properly.
In this article we will give you complete information about Operating System. For the convenience of study, we have divided this article into the following parts.
What is Operating System?
Operating
System, in short form it is called OS, is a computer program that operates
other computer programs. The operating system acts as an intermediary between
the users and the computer system. It explains our instructions to the
computer. Other software programs and hardware are operated by the operating system.
A computer is a non-living thing without an operating system. Because the
operating system makes the lifeless hardware workable and also provides the
functionality to run other software programs on top of the hardware.
The main question is why operating system is needed, what is the importance of
operating system for a computer system? Let us try to understand these
questions below.
Need and Functions of Operating System
This master program (Operating System) controls and operates the entire computer. This is how the computer is managed. Operating System gives the user the ability to work easily on the computer.
Operating System Some key functions - Functions of Operating System
# 1 computer makes the system simple
Signed
data computer system user understands only binary number (0,1). However, it is
not possible to give instructions in binary for the user. Therefore, the user
interface is similar to the ease of preparation in the language of the
operating system.
Therefore, we take you to get to work the way you want Dekr directed computer
in their own language. This is all possible by Os.
# Hidden charges 2 hardware information
When
the user then instructs the computer is a conversation between the hardware and
operating system. About that we do not reveal the meaning and sender. Because
this information is useless for us. Hence, it is hidden fighters.
Thus we have the only answer and the output is displayed. The input given by
our processing is not we see. This is happening between all hardware and
operating systems.
The advantage is that users face hardware heavy does not Sucnaon.
# 3 provides a simple way
Modern
operating system based on GUI (Graphical User Interface). That is, to give the
command does not require any type of coding or programming.
If you want the job to find him solely through button or icon. The desktop icon
is the best example. From here you go on the computer file you just click on
the My Computer icon. And reach.
The graphical user interface has proven to be more simple, user friendly and effective than the early, command line interface (which is still used in many operating systems today). Perhaps this is the reason why computer users are ready to pay money for this.
#4 Mediates
One
of the functions of the operating system is also to mediate. It is the link
between the user and the hardware. Whatever instruction the user gives to the
computer. It accesses the related hardware through the operating system itself.
Suppose, you want to play a song on the computer, then you play the song. You
have given this instruction through the operating system installed in the
computer system. The OS transmits this instruction to the voice hardware ie the
speaker. And in this way you get the output in the form of voice.
#5 Manages resources
The
management and allocation of resources in your computer system is also done by
the operating system itself. How much memory has to be allocated to perform a
particular task, which hardware has to be informed. All this work is done by
the operating system itself.
Suppose, you want to download a 3 MB song in a new folder, then the operating
system will first give 3 MB space for this folder, then the file manager will
do this work.
Different Types of Operating System – Types of Operating System
Operating System has always been with the computer. As the computer developed, the operating system also developed itself. Operating System is divided into several categories. But, here we will know some of the major types of Operating System.
1. Multi-user Operating System
This operating system allows more than one user to work simultaneously.
Hundreds of users can do their work on this operating system at a time.
2. Single-user Operating System
In contrast, Single-user Operating System allows only one user to work at a
time. Many users cannot work on this operating system at a time.
3. Multitasking Operating System
This operating system allows the user to run many different programs
simultaneously. On this operating system, you can also write e-mail at a time
and also chat with your friends.
4. Multi Processing Operating System
This operating system allows a program to run on more than one CPU.
5. Multi Threading Operating System
This Operating System allows different parts of a program to run
simultaneously.
6. Real Time Operating System
Real
Time Operating System processes the input given by the user immediately.
Windows Operating System is the best example of this.
Operating System is a very essential program for the computer. Without it, the
computer is just an inanimate object, it is not wrong to say that. Using a
computer without an operating system can prove to be a very difficult task. To
understand the relationship between Operating System and Computer, you can
understand the above diagram.
Features of Operating System – Characteristics of Operating System
- Tracks primary memory. Like, where is it being used? How much memory is being used? And makes memory available on demand.
- Takes care of the processor i.e. manages.
- Manages all the devices connected to the computer.
- Computers manage both hardware and software.
- Provides security through passwords and other technologies.
- Keeps track of the work performed by the computer and keeps their records.
- Informs you of errors and dangers.
- Creates coordination between User and Computer Programs.
