In the context of computing and information technology, hardware includes all of the physical, tangible components of a computer system that you can actually touch and see. This encompasses internal components such as the central processing unit (CPU), motherboard, random access memory (RAM), hard disk drives, solid-state drives, power supply units, and graphics cards. Additionally, it includes all external peripheral devices attached to the system, such as monitors, keyboards, mice, printers, scanners, and external storage drives. Without hardware, the software instructions that tell a computer what to do would have no physical medium on which to execute or run.
