People also ask what is an operating system and how does it work? An operating system is software that acts as a beer fee for user and computer hardware. The main purpose of the operating system is to make the computer easy for the user to use and to use the computer hardware efficiently. Shall we tell you what is the post of operating system? And the operating system does something.

What is an operating system?
The operating system performs basic computer functions such as taking input from the keyboard, following instructions, and sending output to the screen. The OS controls the computer's memory and processes, as well as the software and hardware.
Each computer must have an operating system to run the Taki Wu Dunya program. The operating system helps me to communicate without knowing your computer language.
The operating system is used to run programs and utilities. This application controls the execution of programs.
Each computer must have an operating system to control the application. Without OS computers are of no use.
UNIX, MS-DOS, MS-Windows - 98 / XP / Vista, Windows-NT / 2000, OS / 2 and Mac OS are some of the popular operating system names.
Some important features of niche operating system are mentioned:
Memory management
Processor management
Device management
File management
security
Controlling system performance
Job calculation
Error detecting AIDS.
Coordination between other software and users
1 # Memory management
Memory management refers to the management of primary memory or main memory. Main memory provides fast storage from which the CPU accesses directly. Any program executes in the main memory.
Memory management works for the operating system for the operating system: which part of the memory will be used and which part will not be used It manages the OS. Multi-programming MOS You decide which process will receive when and how much memory. When an action requests memory, you allocate memory. OS de-allocates memory when an operation does not require memory.
2 # processor management
In a multi-programming environment OS you decide which process to allocate memory for when and for how long. Is the process called process scheduling? The operating system manages the processor at work: and monitors the state of the process. And the task for which the program is responsible is called the use of the traffic controller. Deletes the processor when the process is finished.
3 # Device Management
The operating system manages device communication with the help of the relevant drive. The OS for Device Management performs the following tasks: Sibi monitors the device. And who uses the I / O controller who is responsible for the program, you decide from whom the process will get the device and for how long. The device allocates me efficiently. De-allocates the device.
4 # file management
File systems are usually organized into directories for easy navigation and use. Directories can contain my files and directories. Operates for file management in the operating system: tracking information, location, usage, status, etc. Deciding who has the resources in the mail. Allocating resources. Deploying resources
5 # Other important activities
It lists some of the world's most important activities that the operating system performs.
Security − It prevents unauthorized access to programs and data.
Controls system performance - records delays between service requests and system response.
Job Accounting - Monitoring the time and resources used by different jobs and customers.
AIDS detection error - Dump, trace, error messages and other debugging and AIDS error detection results.
Coordination between other software and users: manages the coordination and assignment of compilers, interpreters, assemblers and other software for different users of the computer system.
Types of operating systems
Use the most common operating systems that are named:
Serial Processing: Serial processing operating system follows the FIFO (First in First Out) framework for processing.
Batch Processing: In batch processing, the work of a single star is prepared and processed.
Real time system: Real time system is used where we need high and timely response.
Distributed Operating System: Does the operating system store and process data at multiple locations?
Multi-processing: Do I have more CPU operating system than you in Tara's operating system?
Parallel Operating System: Manages what is done parallel to the computer's most running resources in the star's operating system.
How does the operating system work?
When the computer is opened, the operating system loads into the program's main memory. What is the program called kernel?
Once the kernel is loaded, the operating system, which is a system program, is ready for the user to run the program. Once ready, the OS application allows the program to use the hardware efficiently.
Operating system features
An operating system is a set of programs that control the execution of a remote program.
Jode controls the input and output device from the OS system, it controls the sub-application software.
The OS process is responsible for allocating memory to what is called scheduling.
OS Bios me is stored. This system also has the necessary information to use to get the start-up walk system implemented. This requires loading the OS into the computer. So the OS has to be styled on the computer's hard disk.

Question : What is an operating system in a computer?
Answer : Operating system is a program that manages all other application programs on a computer after it is initially loaded into the computer through a boot program. Application programs use the operating system by requesting services through a designated application program interface.
Question : What is a operating system Short answer?
Answer : Operating system is a collection of set of programs, which manages all the resources
Question : What is an operating system and give examples?
Answer : Operating system is a collection of set of programs, which manages all the resources. The operating system is system software. Communication between user and system is done with the help of operating system. Examples are Windows, Linux, and Android operating systems that enable the user to use programs such as MS Office, Notepad, and games on a computer or mobile phone.
