What is an operating system? An operating system (OS) is the software that manages all the hardware and other software on a computer. It acts as a bridge between the user and the computer's hardware, ensuring everything runs smoothly. Without an OS, your computer would be useless. Think of it as the conductor of an orchestra, making sure every instrument plays in harmony. From booting up your device to running applications, the OS handles it all. Popular examples include Windows, macOS, Linux, and Android. Each has unique features, but they all serve the same fundamental purpose: making your computer usable.
