The document describes various computer components and their functions for input, processing, output, or storage. The keyboard and mouse are used for input. The central processing unit (CPU) processes data from input devices and performs calculations. Memory components like random access memory (RAM) temporarily store information while processing, and storage devices like the hard drive and USB drives permanently store information and data. Output devices like monitors, speakers, and printers display or produce the processed data. Components like the motherboard, video card, and game controllers facilitate or enhance the functioning of other components.
