Operating System is a collection of software that manages the hardware resources of the computer and provides common services for computer programs. Therefore, it is mandatory to have an operating system to run a computer. Without an operating system, no program or application can work on a computer.(what is device management in operating system)
What is Operating System? (what is device management in operating system)
After reading our (operating system gate) blog completely, you will understand well what is an operating system? Complete information and jobs are going to tell about this in great detail.
Operating system is the most important software running on a computer. It works to manage not only the memory, process of the computer but also all the hardware and software. It is difficult to imagine a computer without an operating system. The operating system is designed in such a way that it can manage all the resources and operations of the computer. The operating system ensures that all programs run well.(advanced operating system)
History of Operating System
The changes in the operating system are divided into generations. The first generation of operating system used to be from 1940 to 1950, this is the time when the computer was being developed.
In fact, the first operating system was created in 1956 by General Motors for IBM 705. Which is called the second generation. After which in 1969, the Unix operating system developed the first version of the operating system. It was written in assembly language for mini computers. This was the third generation of the operating system and the fourth generation of the operating system started with the development of personal computers.(advanced operating system)
Types of Operating System
The operating system is divided into four types based on functionality.
1. Batch Operating System: To do any work in the old computer, it was divided into small groups i.e. batch.
2. Time Sharing Operating System: When the resource capacity is low and the number of users using it is high, then time sharing operating system is used.
3. Multitasking Operating System: Like its name, many tasks can be done simultaneously in this operating system. Because of this, many programs can be opened and worked on simultaneously.
4. Real Time Operating System: It is also called RTOS. In this, a fixed time is fixed to complete any work. If the operating system is not able to work in that time, then the work gets failed.(operating system gate)
Features of Operating System
• Memory Management: The work of managing the memory of the computer is mainly done by the operating system. The operating system also keeps information about which program is using which part of the memory. The operating system also does the work of managing multiprogramming.
• Processor Management: The operating system tracks the status of the process. It also acts as a traffic controller. When a program does not need the processor, the operating system also deals with the task of deallocating it.
• Device Management: The operating system manages device communication through drivers. It also tracks all the devices connected to the system. It is also called I/O controller.
• File Management: The operating system also tracks the file system of the computer. The decision to give resources to any program is taken by the OS itself.
• Security Management: The operating system protects the confidential data of the system and prevents any unauthorized person from accessing the system.
Functions of Operating System
Operating system is very important for the computer, some of its functions are as follows.
- Hardware Management
- Memory Management
- Process Management
- Managing Files
- Security of Confidential Data
- User Interface
- Networking
- Application Support
- Update and Maintenance

Advantages of Operating Systems:-
Ease of Use: Users can easily interact with the window operating system in their computer. Navigation is simple in Windows operating system.
Support for Multitasking: Operating system allows the user to run more than one program at the same time. Which saves time.(advanced operating system)
Data Security: Operating system provides many features to protect our data, such as password protection and encryption
Limitations of Operating Systems
Threat of virus and malware: Pirated windows operating system, there is a high possibility of virus and malware attack, there is a fear of loss of files and windows getting corrupted.
Hardware requirement: New operating systems require more hardware space such as RAM and SSD to run smoothly.
Cost: Many operating systems, such as Windows and macOS, require a license to be purchased, which can also be quite expensive.
How to Choose the Right Operating System?
Choosing the right operating system is an important challenge for you, let’s know how to choose:
Purpose of Use: First of all, you have to understand for what purpose you want to use the operating system, that is, what will be your work.
User Interface: You should choose an operating system whose user interface is intuitive and convenient for you.
Cost: The cost of the operating system is also an important factor.
Support and Updates: Updates keep coming in Windows and macOS from time to time and support is also available from the team.
Conclusion
Operating system is essential to run a computer or mobile. Without an operating system, a computer or mobile cannot work. With changing times, many changes have also come in the operating system, which can be known from the working capacity of today’s computer and mobile.

Frequently Asked Questions (FAQs)
Hardware management, memory management, process management, managing files, security of confidential data, user interface, networking, application support, update and maintenance etc. are the functions of the operating system.
Any computer or mobile can work only when its operating system is working properly. The working capacity of any device depends on its operating system.
The operating system manages all the resources and operations of the computer or mobile.
There are four types of operating systems – batch operating system, time sharing operating system, multitasking operating system and real time operating system.
Examples of operating systems are MS-Windows, Deepin, Free BSD, CentOS, Debian, Solaris, Fedora, Mac OS, iOS, Android, PenPoint OS, Linux, UNIX, etc.
Windows: Gives more customization to the user, has a very popular large software support, and is popular for PCs.
MacOS: Especially for Apple hardware, good in terms of security and graphics.
Linux and macOS are considered more secure as they are less affected by viruses and malware. However, Windows is also an antivirus, due to which Windows can also be safe for you.
