The input devices, such as the keyboard and mouse, allow users to interact with the computer and provide it with data and instructions. This input is then processed by the central processing unit (CPU), which performs calculations, executes programs, and manages the flow of data within the computer.
The CPU communicates with memory, which temporarily stores data and instructions that the CPU needs to access quickly. This memory is typically volatile, meaning that it loses its contents when the computer is turned off.
Finally, the output devices, such as the monitor and printer, allow the computer to communicate with the user by displaying information or producing physical output.
