🔄 How All the Parts Talk to Each Other

Let’s Find Out How Computers Work

The brain (CPU) can’t work alone. It needs help.
It “talks” to the memory, the screen, the keyboard…

But not with sounds or pictures.
They all use signals — electricity.

Wires and circuits!

Inside the motherboard are tiny lines of metal that work like roads.

When the CPU wants to:

…it sends a signal through the wire to that part.

Each part answers back with its own signal.

Imagine if the CPU is a boss.
It sends little notes to each part:

“Hey RAM, send me number 3.”
“Hey screen, draw a red square.”
“Hey storage, save this file.”

Each note travels super fast — as electricity.

There’s a special set of wires called the system bus.
Think of it as a super-highway inside the computer.

The CPU, RAM, and storage all use this same road.
