Advantages of Operating System

What is an Operating System?  

An operating system is an interface that helps to communicate with the user and the computer hardware. Operating systems are used for file management, memory management, process management, etc.

In other words, an operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs.

Now let us discuss the advantages of the operating system:

Advantages of Operating System

Computing source

With the help of Operating Systems, we can communicate with the user and the computer system hardware. We can also improve the performance of any task in the operating system with the help of proper communication.

There are three stages in computing sources:

  • Data input (in this stage, we can take input  as data from the user to put into the system).
  • Processing (we can perform different tasks on the input data)..
  • Output (after we perform the input operation, we can get the deriserd data we want).

We can also perform complex tasks easily when the computer user can efficiently communicate with the computer system.

User-friendly interface

  • The operating system has a very user-friendly interface that is also very easy to use.
  • This is one of the advantages of the operating system. Before the coming of the CLI (Command Line Interface) and GUI (Graphical User Interface), it was very hard to interact with the computer system.
  • If we want to communicate with the system then we must have the knowledge of the commands for the proper interaction.
  • With the arrival of the operating system, we made the graphical user interface more friendly.
  • Because the graphical user interface contains different graphical representations like buttons, check boxes, labels, icons, and symbols. With help of these feature, OS helps users to understand the different components of the computer system.
  • It provides us abstraction. It means, it shows only the needed part and hides the complex part of the system.

Resource sharing

  • The operating system also supports resource sharing. With the help of the operating system, we can share data with different devices and also to multiple users at the same time.
  • It also allows resource sharing. We can easily access the data and information with the help of a remote computer system when the data and information are actually present on the server.
  • If we want to share data with the other system, we can share that data through printers, fax machines, etc.
  • If any client wants to access resources then we require OS on a server. Then the server should have an OS to enable access to its resources for all the clients.
  • We can share resource information with multiple users with the help of emails.
  • With email services in an operating system, we can improve the performance of the computer system.
  • With the help of the operating system functions, we can manage the web browser and email applications.

No coding line

It is very difficult to write commands or code for even simple tasks. As we discussed earlier, GUI (Graphical User Interface) removes the process of writing complex code for doing simple tasks.

Data protection

In the operating system, we generate larger data in stored data in a database which can be accessible by the operating system from anywhere. Operating system offers the security to operate our data smoothly. The computer system should be protected from unauthorized access to data. With the help of a computer system or we can say the operating system, we can use an authentication process so, we can find the identity of the user that are running program, is allowed to execute or not.

There are some steps for user authentication:

  • Username and Password
  • Biometric verification (Fingerprint and face recognition)
  • Authentication (we can recognize with an ID card)

There is one more way to protect the data. We can protect the data with the help of a one-time password OTP. Whenever a user needs to access the computer system then he needs to enter a unique password OTP. OTP can be used only once.

Software update

In the operating system, we have different types of applications and software that are present in our computer system they need regular updates to fix the bugs and issues and also to add new features in the application and software.


An operating system can perform multiple tasks at the same time for multiple users.
