What Is An Operating System? 

An operating system (OS) is critical software that manages computer hardware and software resources. It acts as an intermediary between the user and the computer hardware, making it easier to interact with the machine. OS provides a user interface for interaction with the computer and facilitates the execution of software applications. 

Additionally, operating systems control and manage access to system resources and provide essential cyber security features to protect against unauthorised access or malicious software. Without an operating system, it would be impossible to use a computer effectively. Therefore, understanding its functions is essential for IT engineers with computer systems.

What Is The Importance Of Operating System?

Operating systems are crucial in managing computer hardware and software resources, making them essential for any modern computing device. One of the primary benefits of operating systems is their ability to manage access to system resources and prevent unauthorised access or malicious software. Additionally, the operating system’s functions make it easier for users to interact with the computer by providing a user interface and facilitating the execution of software applications.

Moreover, operating systems ensure efficient memory management, process scheduling, file management, and device management. This contributes significantly to improving overall system performance. In summary, operating systems are critical components of any computing device that perform vital functions such as resource management, security provision, and performance optimisation.

The Key Operating System’s Functions In IT Engineering

Here we have listed the operating system’s functions in IT engineering. Have a look!

1. Process Management  

Effective process management is a crucial operating system’s function. It involves ensuring that each process running on the system has the necessary resources, such as memory and CPU time. 

The operating system must also prioritise processes based on their importance and ensure they are used efficiently. Process scheduling and prioritisation are key aspects of process management. Without proper process management, the system can become unresponsive or crash.

2. Memory Management

Memory management is a crucial function of operating systems that involves allocating and managing the computer’s memory resources for different processes and applications. An effective memory management system ensures that each process has enough memory to run smoothly without interfering with other processes. This function includes virtual memory management, paging, and swapping tasks.

3. Device Management

Managing hardware resources is crucial for the smooth functioning of a computer system, and device management helps achieve this goal. From printers to network adapters, all hardware devices require coordination with software applications, and the operating system serves as a mediator between them. 

Using device drivers facilitates communication between the OS and hardware, enabling efficient usage of resources. Effective device management ensures that all devices are utilised optimally while guaranteeing optimal performance and reliability of the system. Without proper device management, hardware conflicts can lead to system crashes and other issues, making this function a key aspect of operating systems in IT engineering.

4. File Management

Effective file management is a critical purpose of the operating system. The OS enables users to create, organise, and access files through its file management tools. For example, users can easily locate and retrieve files from directories or subdirectories without remembering the file’s exact location. Moreover, the OS ensures that files are protected from unauthorised access or modification by implementing security features such as permissions and encryption.

In addition, modern operating systems provide users with advanced file management functions like compression and backup options. File compression reduces the file size, saving storage space on the device, while backup options help protect against data loss in case of hardware failures or other disasters. Through efficient file management features, operating systems ensure users can store and access files quickly and securely.

5. Security And Protection 

Operating systems are crucial in securing IT infrastructure and protecting valuable data from unauthorised access or theft. The operating system’s functions ensure that sensitive information remains safe and secure by controlling access to files, managing user accounts, and monitoring system activities.

In addition, modern operating systems employ various security mechanisms such as firewalls, encryption, and password authentication to prevent external threats such as viruses or malware from breaching the system’s defences. With these security features, businesses can operate more confidently, knowing their critical data is protected from harm.

The Final Say 

Operating systems are the backbone of modern computing and IT systems. They provide a platform for applications to run on, manage hardware resources, and ensure security and protection. The key operating system’s functions include process management, memory management, device management, file management, and security and protection. Understanding these functions is essential for IT engineers in designing and maintaining efficient and secure computing systems.


1. What is the purpose of an operating system in IT engineering?

An operating system in IT engineering aims to manage computer hardware and software resources. This includes providing a user interface for interaction with the computer and its applications and performing tasks like memory, process, and file management.

2. How do operating systems manage computer resources such as memory and processing power?

Operating systems manage computer resources through resource allocation and scheduling. This includes allocating memory to programs and managing virtual memory when physical memory is limited. In addition, they prioritise tasks based on their importance and manage the computer’s processing power.

3. Can multiple operating systems be used on one device? If so, how does this work?

Yes, using multiple operating systems on one device through dual-booting is possible. This involves creating separate partitions on your hard drive for each operating system and choosing which one to use when starting your device.
