Computer hardware

Computer hardware refers to the physical components that make up a computer system. This includes both internal and external parts such as the central processing unit (CPU), random access memory (RAM), motherboard, storage devices, graphics card, sound card, and the computer case. External devices include monitors, mice, keyboards, and speakers1. Hardware is essential because it runs the software, which are the instructions that tell the hardware what to do. Without hardware, your software would have no home and no way to execute commands.
