What is the function of the operating system?

An operating system is a piece of software that allows users to interact with a computer and run programs. So what is the function of the operating system? Let’s find out with Tnhelearning.edu.vn through this article!

System performance control

The operating system monitors the overall system setup and records the response times between system requests. This can help improve performance by providing critical information needed at the time of troubleshooting .

Support error detection

The operating system detects errors by continuously monitoring the system , which helps us avoid problems related to computer software. For example, when your computer is having problems and needs to be restarted, the operating system will send you an error message and solution on the screen.

Collaboration between other software and users

Operating systems can also help users use other software of the computer system, through interpreters, compilers, assemblers, and other applications.

Memory management

If a program wants to be executed, it must first be loaded into main memory . And in fact, the operating system also controls the main memory on the machine through the following activities:

• Monitor main memory.
• Keep track of the allocated memory address and the unused memory address.
• Decide how long the software must stay and the order in which the software is granted access to memory.
• Allocate memory for a piece of software and release the memory when the software operation ends.

The operating system also has the function of supporting memory management for the computer system

Processor Management

The operating system helps manage the software that has access to the processor and maintains the amount of processing time in a multitasking environment through the following activities:

• Monitor the status of the software.
• The program that monitors the state is called a flow controller .
• Allocate CPU and release processor when not needed.

Equipment management

An operating system manages interaction between devices by means of their respective drivers , through the following operations:

• Monitor all devices connected to the system.
• The operating system specifies a program responsible for every device called an input/output controller .
• Decide which devices and processes are accessed for how long .
• Allocate devices efficiently, and de-allocate devices when they are not required.

File management

A file system organized into folders for easy navigation and use. The operating system manages files by keeping track of where information is stored, user access settings and the status of all files, etc.
