What is the main function of an operating system?

The main function of an operating system is to control major functions and protect information. An operating system serves as the intermediary between computer hardware and software, managing resources such as the CPU, memory, and input/output devices. It facilitates the execution of programs, ensuring that various applications can run smoothly by allocating system resources effectively.

Additionally, an operating system provides security measures that protect the data and user information stored on the device. This includes user authentication, access control, and resource management, which help prevent unauthorized access and data breaches.

While internet speed, graphics creation, and data storage capabilities are important aspects of computing, they are not the primary role of an operating system. Internet speed is influenced by network configurations and hardware, graphics creation is handled by software designed for that purpose, and data storage is a service provided by both the operating system and the hardware, rather than being the sole function of the OS itself.
