systemhardware

System hardware refers to the physical components of a computer system. These components work together to execute instructions and process data. Key pieces of system hardware include the central processing unit (CPU), which acts as the brain of the computer, performing calculations and running programs. The motherboard is the main circuit board that connects all other hardware components. Random access memory (RAM) is the temporary storage where active programs and data are held for quick access by the CPU. Storage devices, such as hard disk drives (HDDs) and solid-state drives (SSDs), provide long-term storage for the operating system, applications, and user files.

Other essential hardware includes the graphics processing unit (GPU), responsible for rendering images and video, and the power supply unit (PSU), which converts wall outlet electricity into usable power for the components. Input devices like keyboards and mice allow users to interact with the computer, while output devices such as monitors and printers display or present the results of the computer's processing. Network interface cards (NICs) enable computers to connect to networks. Together, these physical elements form the foundation upon which software operates.
