This diagram shows the main parts of a computer and how they work together.

Input devices like keyboard and mouse send data to the CPU.

The CPU processes this data and may need to get or store information in Memory (RAM) or Storage.

When you open a file, the CPU asks Storage to send the file data to Memory.

Then the CPU reads the file data from Memory and sends the results to the Output devices like the screen.

This flow helps you understand how hardware parts cooperate to perform tasks, building your intuition about computers.

Variations - 2 Challenges

[intermediate] Draw a flowchart showing how the CPU processes data from input to output including decision making (e.g., checking if a file exists before opening).

[advanced] Draw a detailed diagram showing how data moves between CPU registers, cache, RAM, and storage when running a program.
