Tech Foundations: Before You Code

Module 1: How Computers Work

Welcome to the very first module of Tech Foundations. Before you write a single line of code, before you build a website or an app, you need to understand the machine sitting in front of you. What is it actually doing when you tap a key, open a file, or scroll through your M-Pesa messages?

Module 2: The Internet Demystified

Module 3: Operating System Fluency

You already know what an operating system is -- Module 1 covered that. You know what the internet is and how it works -- Module 2 handled that. Now it is time to stop just understanding your computer and start truly working with it.

Module 4: Meet the Terminal

Welcome to the module that changes everything. Up until now, you have been learning concepts — how computers work, how the internet functions, how your operating system organizes files and folders. All of that was preparation for this moment.

Module 5: Computational Thinking

Welcome to the heart of this entire course.

Module 6: How Software Is Built

You have spent the last five modules understanding how computers work, how the internet connects them, how operating systems manage everything, how the terminal gives you direct control, and how to think like a programmer. Now it is time to look at the big picture: how does software actually come together?

Module 7: Version Control Concepts

Every piece of software you use — from M-Pesa to WhatsApp to the browser you are reading this on — was built by teams of people changing code thousands of times over months and years. How do they keep track of all those changes? How do they avoid overwriting each other's work? How do they undo a mistake without losing everything else?

Module 8: Digital Hygiene and Safety

Module 9: How to Learn Tech

Module 10: The Tech Career Landscape

You have made it. This is the final module of Tech Foundations: Before You Code — and it is a special one.
