PC hardware refers to the physical components that make up a personal computer. This includes essential parts like the central processing unit (CPU), which acts as the brain of the computer, and the motherboard, which connects all components. Other important hardware includes random access memory (RAM), which temporarily stores data for quick access, and storage devices like hard drives or solid-state drives (SSDs) that hold files and programs. In addition to these core components, PC hardware also encompasses peripherals such as keyboards, mice, and monitors that allow users to interact with the computer. Graphics cards, which render images and videos, are also crucial for gaming and graphic design. Together, these elements work in harmony to enable a computer to function effectively.
