Computer hardware refers to the physical components of a computer system that can be touched and manipulated by the user. It encompasses a wide range of devices, including the central processing unit (CPU), memory modules, storage devices (such as hard disk drives and solid-state drives), input/output devices (like keyboards, mice, and computer monitors), and various expansion cards. The history of computer hardware dates back to the mid-20th century with the introduction of early electronic computers such as the ENIAC (Electronic Numerical Integrator and Computer) in 1946. Since then, hardware technology has advanced rapidly, leading to the development of smaller, faster, and more powerful hardware components, as evidenced by Moore's Law, which predicts that the number of transistors on a ]microchip will double approximately every two years, driving continual improvements in computing performance and computing efficiency.
