About This Course

Every device you touch — your phone, laptop, smart TV — is a computer. Yet most people have no idea how they actually work. This course changes that.

We start from the very beginning: what a computer is, how it evolved from room-sized machines to pocket-sized chips, and how billions of tiny transistors work together to process information. We then move through every major hardware component — CPU, RAM, storage, motherboard, input/output devices — explaining what each does, why it exists, and how it connects to everything else.

The second half covers software: what it really is, how operating systems manage hardware, and how the software you run every day is built on layers of invisible infrastructure. By the end, you will understand exactly what happens from the moment you press the power button to the moment your desktop appears.
