A computer is an electronic device that accepts, processes, stores, and outputs data. It has two main parts: hardware and software. Hardware includes the CPU, memory, storage, input devices (keyboard, mouse), and output devices (monitor, printer). Software includes operating systems (Windows, macOS, Linux) and applications (Microsoft Office, Google Chrome). The Windows operating system has key features like the Desktop, Taskbar, Start Menu, and Notification Area. Common shortcuts like Ctrl+C (Copy) and Ctrl+V (Paste) make using a computer easier.
