The Basic Parts of a Computer, Explained Simply
If you feel lost with the terminology, here are the essential parts of a computer explained without assuming you already know them.

On the inside
- Processor (CPU) — the one that runs everything, the "brain."
- RAM — temporary working memory, empties when you turn off.
- Storage (SSD/HDD) — where your files are kept permanently.
- Motherboard — connects everything together.
- Graphics card (GPU) — processes what you see on screen.
On the outside (peripherals)
- Monitor — displays the image.
- Keyboard and mouse — how you interact with the system.
- Speakers or headphones — sound output.
The difference between RAM and storage, in short: RAM is like your desk (it empties at the end of the day); storage is like a filing cabinet (it keeps things permanently, even after you close the office).
Tip: you don't need to understand every part in depth to use a computer normally — this list works as a reference for whenever you come across a term you don't recognise in a guide or technical conversation.
Frequently asked questions
What's the difference between RAM and storage?
RAM is temporary working memory that empties when you turn the machine off. Storage (SSD/HDD) keeps your files permanently, even when it's off.
Do I need to know all these components to use a computer?
No, it's useful as a general reference, but normal daily use doesn't require understanding each individual component in depth.
