operating system

An operating system is basic software that manages computer hardware and lets applications run smoothly in simple terms. It controls the processor, memory, and storage. When you open a program, the operating system assigns resources and directs tasks in order. It also keeps track of files, sending them to and from the hard drive.

Device drivers connect keyboards, mice, printers, and many other hardware components, making them work with your computer. The operating system checks user passwords and permissions to keep data secure. It offers a clear interface, often using windows, icons, and menus, so people can use the computer easily.

Networking tools let you connect to the internet or a local network, sharing files and printers. Some operating systems run on desktops and laptops, like Windows or MacOS. Others power phones and tablets, such as Android or iOS. Real-time and embedded systems control machines in cars, appliances, and factories.
