Computer components are the essential parts that make up a computer system. The main components include the central processing unit (CPU), which acts as the brain of the computer, and the motherboard, which connects all the parts together. Other important components are the random access memory (RAM) for temporary data storage, and the hard drive or solid-state drive (SSD) for long-term data storage. Additionally, graphics processing units (GPUs) are crucial for rendering images and videos, especially in gaming and graphic design. Power supplies provide the necessary electricity to all components, while input devices like keyboards and mice allow users to interact with the computer. Output devices, such as monitors and printers, display or produce the results of computer processes.
