What Is Raspberry Pi? (Quick Definition)
Raspberry Pi is a family of low-cost computers designed to run Linux (usually Raspberry Pi OS) on a small board — called a single-board computer (SBC).
Unlike Arduino-type devices, Raspberry Pi behaves more like a real PC:
- multitasking OS
- file system
- apps and browsers
- networking tools
- programming environments
✅ It’s basically a tiny Linux computer that you can use for learning, building, and automation.

Why Raspberry Pi Was Created (The Original Mission)
The Raspberry Pi was created in the UK with a very specific goal:
help students learn computer science using affordable hardware.
At the time:
- PCs were expensive for many schools
- many students had limited access to programming
- the “maker” culture was growing fast
So Raspberry Pi made a board that was:
✅ cheap
✅ small
✅ capable of running Linux
✅ good enough to teach programming
That mission is still alive today — but Raspberry Pi also became a platform for hobbyists and professionals.
