What is an operating system and how does it work
What is an Operating System?
Some Major Functions of Operating System – Functions of Operating System in Hindi
#1 Makes Computer System Simple
The computer system understands the data entered by the user in binary numbers (0,1) only. However, the user can't give instructions in binary. Therefore, the operating system gives the facility to prepare the user interface in its own language.
Therefore, we and you get the desired work done by watching the instructions on the computer in our own language. All this is possible through the OS.
#2 Hardware hides information
The conversation between the hardware and the operating system occurs when the user gives instructions to the computer. We, the end-user, do not know about that. Because this information is useless for us. Therefore, it is hidden.
Thus we only see the answer and the output. The processing of the input given by us is not visible to us. All this happens between the hardware and the operating system itself.
The advantage of this is that users are not faced with heavy hardware information.
#3 Provides easy means
The modern operating system is based on GUI (Graphical User Interface). That is, no coding or programming is required to give commands.
You can complete the work you want to do only through the button or icon. Your desktop icons are a great example of this. From here you have to go to the computer file, then 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 meditate. 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 a computer, then you play the song. You have given this instruction through the operating system instled 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 are also done by the operating system itself. How much memory has to be allocated to perform a particular task, and which hardware has to be informed. All this work is done by the operating system itself.
Suppose, you want to dwnle a 3 MB song to 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 Systems in Hindi
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 systems.
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 an 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, a 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 in Hindi
- 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 done by the computer and keeps their records.
- Informs you of errors and dangers.
- Creates coordination between User and Computer Programs.
Major operating system names
- Windows OS
- Mac OS
- Linux OS
- Ubuntu
- Android OS
- iOS
- MS-DOS
- Symbian OS
