How Computers Work

1. Computers are electronic devices that process data to perform various tasks. They work by using components like the central processing unit (CPU), memory, storage, and input/output devices. When you interact with a computer, input is provided through devices like the keyboard and mouse, which is processed by the CPU. The CPU then executes instructions stored in memory to carry out tasks like running programs or displaying information on the screen. Data is stored in different types of storage devices, such as hard drives or solid-state drives, for later use. Computers communicate with external devices through input/output ports, enabling data transfer. Overall, computers rely on complex hardware and software interactions to function and perform the multitude of tasks we use them for every day.
