Hardware refers to the physical components of a computer system that can be seen and touched. It encompasses a wide range of devices, including the central processing unit (CPU), memory modules, storage drives, input/output devices, and various peripheral devices. These components work together to enable the execution of computer programs and the processing of data. The CPU, often referred to as the brain of the computer, performs calculations and executes instructions. Memory modules store data and instructions that the CPU needs to access quickly. Storage drives, such as hard disk drives and solid-state drives, provide long-term data storage. Input devices, such as keyboards and mice, allow users to interact with the computer, while output devices, like monitors and printers, display information or produce hard copies of data. The hardware of a computer system forms its physical foundation, enabling the execution of software and the completion of various tasks.
