A computer is an electronic device designed to process data and execute instructions. It comprises hardware components like the Central Processing Unit (CPU), which performs calculations and executes commands, memory (RAM) for temporary data storage, and storage devices such as Hard Disk Drives (HDDs) or Solid State Drives (SSDs) for long-term data retention. Computers use input devices (e.g., keyboards, mice) to receive data and output devices (e.g., monitors, printers) to display or produce results.
Software, including operating systems like Windows or macOS and applications such as web browsers or word processors, directs the computer's operations. By executing programmed instructions, computers perform a wide range of tasks, from simple calculations to complex simulations, and are essential in fields like business, education, and entertainment. Their versatility and efficiency make them central to modern technology and daily life.
