Plain-language summary
A computer relies on an operating system to coordinate its basic operations. The operating system acts as an intermediary between the computer’s hardware, application software and user. Without it, users would have difficulty running programmes and making effective use of components such as the processor, memory, storage devices and input/output equipment.
This 2013 mini project introduced the role of operating systems and reviewed explanations of how they manage hardware resources and provide an environment for application software. Its discussion covered the coordination of components, the management of memory and storage, the handling of input and output, and the relationship between operating systems and programmes installed on a computer. The project used a review-based approach, drawing on literature and explanatory sources rather than reporting a survey or experiment.
The central message is that the operating system is fundamental to the practical operation of a modern computer. It helps applications use available resources and enables hardware components and software to work together. This provides a basic conceptual foundation for understanding computer maintenance and troubleshooting.
