What is the primary purpose of an operating system?

The primary purpose of an operating system is to manage computer hardware and software resources. This includes facilitating the interaction between the user and the computer, as well as ensuring that different software applications can run efficiently without interfering with one another.

An operating system is responsible for essential functions such as memory management, process scheduling, and input/output control, which are crucial for the overall operation of a computer system. It provides a user interface through which individuals can interact with the software applications and the hardware components, thereby bridging the gap between the physical machine and the user.

While the other options touch on aspects of computing, they do not encompass the fundamental role of an operating system. Enhancing internet browsing speed, optimizing video game performance, and improving data encryption methods are all specific functions that may be influenced by software applications but are not the central purpose of the operating system itself.
