What is AI (Artificial Intelligence)? Complete Beginner’s Guide in 2025

🧠 What is AI?

AI (Artificial Intelligence) refers to machines or software that can perform tasks that usually require human intelligence — such as learning, reasoning, problem-solving, and decision-making.

Some simple examples of AI include:

• Voice assistants like Siri or Google Assistant

• Chatbots (like me 😄)

• YouTube’s video recommendation system

• Self-driving cars

🔍 Types of AI:

There are 3 main types of AI:

1. Narrow AI (Weak AI)

• Designed for specific tasks only

• Example: Face recognition, spam filter

2. General AI (Strong AI)

• Works like a human brain, not yet fully developed

• Can think, reason, and make decisions on any topic

3. Super AI

• Smarter than humans

• Future concept (not existing yet)

⚙️ How AI Works:

AI uses:

• Data (large amount of examples)

• Algorithms (rules for decision-making)

• Machine Learning (ML) – AI learns from past data

• Deep Learning – advanced brain-like structure

For example:
If you show an AI 1000 photos of cats and dogs, it will learn how to tell the difference between them.
