Hardware refers to the physical components of a computer system that can be touched and manipulated. It includes devices such as the central processing unit (CPU), memory modules, storage devices (e.g., hard drives or SSDs), input devices (e.g., keyboard and mouse), output devices (e.g., monitor and printer), and other peripheral devices. Hardware components work together to execute software instructions and perform various computing tasks. Advancements in hardware technology, including faster processors and larger storage capacities, continually contribute to the evolution and improvement of computer systems. Hardware is a fundamental aspect of information technology, influencing the overall performance and capabilities of electronic devices.
