A computer is an electronic device that processes data and performs calculations automatically. It consists of hardware components like a monitor for display, a keyboard and mouse for input, and a CPU that acts as the brain of the computer. Computers can store, retrieve, and manipulate information to help us solve problems, complete tasks, and connect with others around the world.
Computer hardware consists of physical components that work together to process information. The CPU is the brain that executes instructions. RAM provides temporary storage for active programs. Storage devices like hard drives keep data permanently. The GPU handles graphics processing. All these components are connected through the motherboard and powered by the power supply unit.
