OS stands for Operating System, and it is the essential software that performs all the necessary tasks in a computer. Without an operating system, a computer cannot function. It acts as a bridge between the user and the hardware, managing all critical operations such as file handling, memory management, task scheduling, device control, and system security.

When you turn on your computer, the operating system is the first software that loads. It manages all hardware components (like CPU, RAM, and storage devices) and ensures that software programs can run smoothly. Whether you're saving a file, printing a document, or browsing the internet, the OS is working in the background to control and coordinate everything.
