What is the function of Operating System ?

An operating system (OS) provides an interface between the hardware and the software on a computer. It manages resources such as memory, disk space, and processor time in order to provide a smooth and consistent user experience. The OS also provides a platform on which applications can be run.

What is an Operating System?

The operating system is the main program that runs on your computer. It’s responsible for handling all of the basic tasks like starting up, shutting down, and running programs. Your computer usually comes with one pre-installed, but you can also install different ones if you want.

What are the Different Functions of an Operating System?

The functions of a computer’s operating system include :

  1. Starting up the computer
  2. Shutting down the computer
  3. Managing memory
  4. Running programs
  5. Managing files
  6. Protecting files
  7. Relaying data

An operating system (OS) is a set of programs that manage a computer’s resources and provide an interface between the user and the hardware. An OS interacts with a hardware component, such as a network card or peripheral, to give the user access to its functions.

Role of Operating System in Computer Hardware:

Every computer has a central processing unit (CPU), memory, input/output devices, and a storage device. These components work together to run applications, access data, and communicate with other systems. The operating system oversees all these tasks and manages resources used by the applications running on the computer.

It also provides an interface to users and manages security settings. The operating system is the brain of the computer system. It divides up resources and does tasks, such as managing applications and data storage. An operating system allows different components to interact with each other in a way that makes sense.

Role of Operating System in Computer Software:

Operating systems play an important role in computer software. Operating systems provide the basic framework for managing resources and allowing applications to interact with each other. They also control how applications can access files and data on the hard drive, as well as how they can communicate with other devices connected to the computer.

Operating systems also manage how applications use system resources (such as CPU, memory, and hard drive space) to perform their tasks. This is called resource management. Operating systems organize the resources of the computer so that applications can access them without disrupting or interfering with each other.

Differences between Traditional and Modern Operating Systems:

Computer systems have evolved over the years, from the early text-based operating systems to the graphical user interfaces of modern operating systems. There are a number of important differences between these two types of operating systems.

One major difference is that traditional operating systems were designed to be used on mainframes, which were massive and expensive computers. Modern operating systems are designed for use on personal computers, which are much smaller and cheaper.

Another key difference is that traditional operating systems were designed to run one program at a time. Modern operating systems allow multiple programs to be running at the same time, so they are better suited for tasks such as multitasking and online gaming.

The traditional operating systems also rely on manual processes to manage their files and folders. This can be difficult for novice users, who may not understand how these processes work.

Future of Operating Systems:

As technology advances, newer and more sophisticated operating systems are created to cater to the needs of users. Operating systems are expected to become more user-friendly, allowing novice users to easily navigate and understand the operating system.

For example, operating systems may be accessible through different devices such as smartphones and tablet computers.

What will the future of operating systems look like?

The future of operating systems is unclear, but there are several possibilities. Some believe that more specialized operating systems will be developed to better address the needs of specific industries, while others believe that a universal operating system will eventually be developed. In any case, the future of operating systems is an exciting and intriguing topic to consider.

Will they continue to evolve, or will they become obsolete?

With each new model year, it seems that the smartphones we use are becoming more and more obsolete. For example, the newest iPhones only have a 10-year battery life. This is because they are constantly being upgraded with new features and hardware, which means that there are older models that no longer receive updates or support.

This has led to a decrease in sales of older phones, and some experts predict that this trend will continue for the next few years. While it is understandable that phone companies want to keep people using their latest models, it may mean that these devices will eventually become obsolete and no longer function as well as they used to.

What role will software developers play in the future development of Operating Systems?

As the software development landscape changes, so too does the role of software developers. Operating systems are morphing from monolithic, centrally managed codebases to more distributed and collaborative systems.

Developers are needed to build these new systems from scratch, or adapt existing ones to meet this new demand. In fact, operating system development is becoming one of the most important roles in software engineering.

So what will be the future of software development?

It seems that developers will continue to play a vital role in building tomorrow’s operating systems.

What are the 5 main functions of an Operating System?

1. Controls the backing store and peripherals such as scanners and printers.

An operating system (OS) manages the resources of a computer, such as the processor and memory. It provides an interface between applications and the hardware, and facilitates communication between applications and the user.

An OS usually includes an instruction set, a library of functions, and support for devices such as keyboards, monitors, printers, etc. OSes are found on desktops and laptops as well as embedded systems.

A typical function of an OS is to provide an environment in which users can work with software applications.

2. Deals with the transfer of programs in and out of memory.

An operating system is a program that manages the resources of a computer, such as memory, storage, and input/output devices. It provides an interface to the user by providing commands that allow applications to be run.

3. Organises the use of memory between programs.

Operating System is a program that helps organise the use of memory between different programs. It allows for the smooth running of multiple programs by keeping track of where data is and how it is being used.

Without an Operating System, it would be difficult to keep track of all the different programs running on your computer at once and which ones were using which parts of your memory.

4. Organises processing time between programs and users.

The operating system (OS) is a program that organizes processing time between programs and users. It manages resources, such as files and memory, and gives programs access to them. The OS also helps to keep track of user activities so that the computer can provide an optimal user experience.

5. Maintains the security and access rights of users.

An operating system (OS) is the fundamental component of any computer system. It provides an interface between users and the hardware, as well as a set of basic services that allow users to interact with their computers.

An OS also manages security and access rights for users, facilitates communication between different parts of the system, and keeps track of user sessions and changes to files.


An operating system (OS) is the set of software that manages an computer’s hardware and provides common services for software that runs on it. An OS helps to optimize the performance of these programs by providing a platform for shared resources and providing security mechanisms. Furthermore, an OS facilitates communication between applications and the underlying hardware. Operating systems are critical in enabling users to carry out their work tasks, as they manage all aspects of the computer system from its startup to its shutdown.
