Evolution of Computer Hardware

Computers have undergone significant changes over the years. The mouse, which was once big and had a ball underneath, now comes in various forms like touchpads and touch screens. The old bulky screens have been replaced by thinner and lighter flat screens, providing clearer pictures and words. Similarly, keyboards have evolved, although their functionality remains the same. The old keyboards were bigger, had buttons that made clicky sounds, while the modern ones are quieter and more compact.
