What is AI? Your First 10 Minutes
Artificial intelligence isn't science fiction — it's in your phone, your inbox, and your search bar. Let's start with what AI actually means, how it works at a high level, and why it matters for your career.
What is artificial intelligence?
AI is software that learns patterns from data instead of following exact instructions.
Traditional software is like a recipe book — you give it step-by-step instructions, and it follows them exactly. AI is more like teaching someone to cook — you show them thousands of dishes, and eventually they figure out how to make new ones on their own.
When your email app filters spam, when your phone recognises your face, when a chatbot answers your question — that’s AI. It’s not magic. It’s maths, data, and clever engineering.
AI vs traditional software
| Feature | Traditional Software | AI Software |
|---|---|---|
| How it works | Follows explicit rules written by a developer | Learns patterns from data during training |
| Handles new situations | Only if a rule exists for that case | Can generalise from training to new inputs |
| Example | 'If email contains X, move to Spam folder' | 'Based on patterns in 1 million emails, this looks like spam' |
| Gets better over time? | Only if a developer updates the rules | Can improve with more or better training data |
| Needs data? | Only configuration | Needs large amounts of training data |
The AI landscape — what you’ll learn in this cert
The AI-901 exam covers six types of AI workloads. Think of them as different skills AI can have:
| AI Workload | What It Does | Real-World Example |
|---|---|---|
| Generative AI | Creates new content (text, images, code) | ChatGPT writing an email draft |
| Agentic AI | Takes actions and makes decisions autonomously | An AI agent booking a meeting based on your calendar |
| Text analysis | Understands and extracts meaning from text | Detecting negative sentiment in customer reviews |
| Speech | Converts speech to text and text to speech | Meeting transcription, voice assistants, real-time captions |
| Computer vision | Analyses images and video | A hospital AI flagging abnormalities in X-rays |
| Information extraction | Pulls structured data from documents | Reading invoice numbers from scanned PDFs |
Where does Microsoft fit in?
Microsoft’s AI platform is called Microsoft Foundry (formerly Azure AI Studio). It’s where you deploy AI models, build AI-powered apps, and create intelligent agents — all within Azure.
The AI-901 exam splits into two halves:
- Domain 1 (40-45%): Understand AI concepts — what AI can do, how it works, responsible AI
- Domain 2 (55-60%): Build AI solutions in Foundry — deploy models, write prompts, create apps
This module gets you oriented. The rest of the course goes deep on each area.
Meet the characters
Throughout this course, you’ll follow four organisations using AI:
| Character | Who They Are | AI Use Cases |
|---|---|---|
| 🏥 MediSpark | Healthcare startup, 40 staff | AI diagnostic assistant, medical image analysis, patient document extraction |
| 🎓 Priya | Computer science student | Learning Azure AI, first Foundry project, exploring models |
| 🏢 DataFlow Corp | Enterprise analytics company, 2000 employees | AI at scale, speech transcription, customer support agents |
| 🌿 GreenLeaf | Sustainable agriculture co-op | Crop image analysis, invoice extraction, weather report generation |
These scenarios help anchor abstract concepts to real situations — exactly how the exam tests you.

Knowledge Check
MediSpark wants to automatically read patient intake forms (handwritten PDFs) and extract the patient's name, date of birth, and insurance number into their database. Which AI workload type best describes this task?
Priya is learning about AI and reads that 'AI learns patterns from data.' What makes this fundamentally different from traditional software?
