Start here — what a computer is
Brand new to this? Start here. What a computer actually does, input → process → output, and the everyday words — hardware, software, file, bit — in plain language.
Hardware & how it works
The CPU, memory (RAM) and storage, input and output devices, and how binary lets a machine represent everything as 0s and 1s.
Software & operating systems
What an operating system does, applications vs system software, files and folders, and how a program becomes something the computer can run.
Data, networks & the internet
How devices connect, what the internet and the web really are, IP addresses and servers, and how a page reaches your screen.
Programming basics
Variables, input and output, decisions and loops, what an algorithm is, and how to think through a problem step by step.
Databases & the cloud
What a database is (tables, records, fields), why we store data in a structured way, and what "the cloud" actually means.
