Operating system (OS) is a system software (program) that, after it is initially loaded into the computer by the BIOS’s boot program, manages all other application programs in the computer.
Through this operating system software, computer users can directly interact with the operating system through various interfaces, such as a graphical UI (GUI) or command-line interface (CLI).
It acts as an interface between the computer user and the computer hardware. Application programs access the operating system by requesting services through a defined application program interface (API). Let us try to understand this in more simple words.
Just as it is necessary to have a soul in a human body to run it, similarly to run a computer system it is necessary to have an operating system in it. An operating system is a system software that is a set of programs in different types of computer programming languages.
A computer system can not run without an operating system. Without an operating system, a computer is just a plastic, glass, and iron structure and other things called hardware. The operating system manages the computer’s input devices, output devices, memory, CPU, etc.
The operating system provides such facilities so that other application software can also come inside the operating system and perform its work on the computer.
Operating System performs basic tasks such as:
- Memory management.
- File management.
- Process management.
- Handling input and output.
- Controlling peripheral devices such as disk drives and printers.
The operating system has some general responsibilities such as recognizing the input given by the keyboard or anyone else in the computer, getting it executed from the CPU and displaying it on the computer monitor, keeping the records of files safe in the computer’s memory, and Managing them includes managing other essential devices connected to the computer such as disk drivers, printers, speakers and providing the interface of various programs running simultaneously, such as providing the interface between the computer user and the computer hardware.
The GUI of the operating system provides ease in the ability to work on the computer through what is called a graphical user interface. The operating system also manages the computer’s various hardware and application programs. When there is more than one user on the computer, the operating system provides memory management, input/output management, management of various types of processes/resources, security, etc.

Finally We can say that operating systems act as an intermediary between users and computer hardware and run other applications. Nowadays, Microsoft company’s operating systems like Windows XP, Windows 7, Windows 10, and Windows 11 are very popular all over the world.
It is not that only Microsoft company makes operating systems, other companies also make operating systems like Apple company’s Mac OS and Linux, There are many operating system flavors but Microsoft company’s operating systems are more user-friendly and have a graphical interface. On which even an unknown person can work.
Types of Operating Systems :
Operating systems, or OS, are the backbone of our digital computer, and they come in diverse flavors to meet different needs. Let’s explore the various types of operating systems one by one.
Real-Time Operating System (RTOS): Real-Time Operating System ensures precise execution of tasks within strict time limits, crucial for applications like air traffic control.
Single-User, Single-Task: These basic operating systems (OS) are found in simple gadgets like microwave ovens, handling one task at a time.
Single-User, Multi-Tasking: Most desktops and laptops run on this type. They let you multitask efficiently, switching between various applications seamlessly.
Multi-User: Often seen in offices and server environments, multi-user OS allows multiple users to access and work on a single computer.

Network Operating System (NOS): These facilitate resource sharing and communication in networked environments.
Open Source Operating System: Community-driven systems like Linux offer freedom and customization.
Closed Source Operating System: Proprietary OS like Windows guard their source code closely.
Choosing the right OS depends on your device and your specific requirements, as each type brings a unique set of benefits and limitations to the digital table.
Functions of Operating System :
As we know well by now the Operating System (OS) is the main system software (program) of our computer system. Who quietly manages multiple tasks to ensure that everything runs smoothly. These behind-the-scenes actions include:
File System Management: It organizes your files, ensuring they’re stored, retrieved, and modified accurately, making the ‘Save’ button your best friend.
Memory Management: It keeps track of every byte of your device’s memory, making sure each application gets the space it needs without encroaching on others.
Process Management: The OS is the traffic cop, allocating resources and handling multitasking, so you can run multiple applications simultaneously.
Device Management: When you plug in your printer or attach a USB drive, the OS makes sure your computer can talk to and use these devices without a hiccup.
User Interface: Whether it’s the slick icons on your smartphone or the desktop of your computer, the user interface is the face of the OS, allowing you to interact with your device.
Security: It safeguards your data and privacy, implementing firewalls, user authentication, and encryption to keep you safe from digital threats.
Networking: The OS makes it possible for your device to connect to the internet and communicate with other devices on a network.
Error Handling: When something goes wrong, and it sometimes does, the OS helps identify the issue and might even attempt to fix it, preventing your computer from crashing.
Power Management: For laptops and mobile devices, the OS manages power consumption, ensuring your battery lasts as long as possible.
Updates and Maintenance: Your OS takes care of system updates, ensuring your device is equipped with the latest features and security patches.
In summary, the operating system (OS) is the perfect multitasker program, handling all these tasks and more to create a seamless, user-friendly experience, allowing us to work, play, and connect with the digital world very easily.
Examples of operating systems and companies that develop operating systems:
The world of operating systems is dominated by a few major players, each offering its own unique strengths. Let’s take a look at the top contenders:
