Understanding How Computers Work

The video explains how computers work by detailing the processes of input, processing, output, programming, and storage. It uses examples like video calls and calculators to illustrate these concepts. Input devices send information to the computer, which processes it using the CPU, and then outputs it through output devices. Programming provides the instructions for processing, while storage saves data for future use.
