How computers work

A computer is a factory. Every part is a department.

Nothing inside a PC is magic. Each component does one kind of job and hands its results to the next one. Follow a single click through the building.

You click an iconThe CPU (the manager) receives the instruction and decides what needs to happen.
Files leave the warehouseThe program's files are read from storage (SSD/HDD), where they live permanently.
They land on the workbenchFrequently used data is kept in RAM, so the CPU can grab it instantly.
The picture is drawnThe GPU renders what you see and sends the frames to your monitor.

Learn

Understand hardware without a technical background

Each lesson starts with an everyday comparison, then shows what the part really does, why it matters, what happens when it's too weak, and what to look for when buying. Play with the demo at the end.

PC Builder · Beginner mode

Build a PC based on your budget

Answer four plain-language questions. We'll pick parts that work together, explain every decision, and show you cheaper and faster alternatives.

Prices are estimates. This prototype is not connected to a live store or pricing API. All prices are approximate Vietnamese market figures kept in one editable table (PARTS in the page source) and shown with an "est." label. Always check current prices before buying.
Compatibility Checker

Do these components work together?

Pick the parts you're considering. We check sockets, memory generation, physical clearance, power and connectors against each part's real specifications — not just its name — and explain each result in plain language.

Your parts

Specs in this database are taken from manufacturer spec sheets but kept short for teaching. Items marked "Requires verification" need a check against the exact product page before you buy.

Community guidelines

  • Explain, don't gatekeep. Assume the reader has never opened a PC.
  • Use the analogy first, the acronym second.
  • Never mock a basic question. We all had a first build.
  • Say what you'd buy and why. Link your sources.
  • Mark the reply that solved your problem.
