Computer parts are the individual components that make up a computer system. The main parts include the central processing unit (CPU), which acts as the brain of the computer, and the motherboard, which connects all the components together. Other essential parts are the random access memory (RAM) for temporary data storage, and the hard drive or solid-state drive (SSD) for long-term data storage. Additional components include the power supply unit (PSU), which provides electricity to the computer, and the graphics processing unit (GPU), which handles rendering images and videos. Input devices like the keyboard and mouse allow users to interact with the computer, while output devices such as the monitor display the information processed by the system.
