1. What is Artificial Intelligence?

Artificial Intelligence (AI) is a branch of computer science that develops systems capable of performing tasks that normally require human intelligence.

These tasks include learning, reasoning, understanding language, recognising patterns, analysing information, making predictions, solving problems, recognising images and assisting humans in decision-making.

Simple definition: AI is the technology that enables computers and machines to perform intelligent tasks.

Examples of Artificial Intelligence

• Voice assistants
• Recommendation systems
• Face recognition
• Spam filtering
• Fraud detection
• Navigation and route prediction
• Search engines
• Medical image analysis
• Chatbots
• Autonomous systems

2. What is Generative AI?

Generative Artificial Intelligence (Generative AI or GenAI) is a type of AI that can create new content based on patterns learned from large amounts of data.

Unlike traditional AI systems that mainly classify, predict or analyse existing information, Generative AI can produce new text, images, audio, video, computer code, presentations, summaries and other forms of content.

In simple words: Traditional AI often answers: "What is this?" Generative AI can answer: "Create something new based on this."

Generative AI can create:

📝 Text

Articles, emails, reports, stories, summaries, questions and explanations.

🖼️ Images

Illustrations, posters, advertisements, artwork and concept images.

🎬 Videos

AI-generated videos, animations, advertisements and educational content.

🎵 Audio

Speech, voiceovers, sound effects, music and audio summaries.

💻 Code

Programs, functions, scripts, debugging suggestions and documentation.

📊 Presentations

Slides, outlines, speaker notes, diagrams and presentation content.

3. Artificial Intelligence vs Generative AI

Feature	Traditional AI	Generative AI
Main purpose	Analyse, classify, predict or automate	Create new content
Output	Predictions, classifications, recommendations	Text, images, audio, video, code and more
Example	Spam detection	Writing an email
Another example	Face recognition	Generating an image from a text description
Interaction	Often task-specific	Often conversational and multimodal

4. How Does Generative AI Work?

Generative AI systems are generally built using machine learning models that learn patterns from large datasets.

Step 1 – Data

The model is trained using large amounts of information such as text, images, audio, video or code.

Step 2 – Training

Machine learning algorithms learn statistical patterns and relationships within the training data.

Step 3 – Model

The trained model learns how different pieces of information relate to each other.

Step 4 – Prompt

A user provides an instruction, question, image, document or other input.

Step 5 – Generation

The AI model produces an output based on the input and patterns it has learned.

Step 6 – Human Review

The output should be checked, edited and verified before important use.
