18. What is Artificial Intelligence?
Artificial Intelligence (AI) is a branch of computer science that focuses on
creating machines capable of performing tasks that normally require
human intelligence.
These tasks include thinking, learning, reasoning, problem solving,
decision making, and understanding language.
Definition of Artificial Intelligence
Artificial Intelligence refers to the simulation of human intelligence in machines that are programmed to think like humans and act intelligently.
In simple words, AI enables machines to think, learn, and make decisions
like human beings.
Why Artificial Intelligence is Needed
- To reduce human effort in repetitive tasks
- To solve complex problems quickly
- To analyze large amounts of data accurately
- To make machines intelligent and efficient
- To improve decision making
Characteristics of Artificial Intelligence
- Learning Ability: AI systems can learn from data and experience
- Reasoning: Ability to solve problems logically
- Decision Making: Can choose the best option automatically
- Automation: Works without continuous human intervention
- Accuracy: Produces precise results with minimal errors
Types of Artificial Intelligence

Difference Between Human Intelligence and Artificial Intelligence
| Human Intelligence | Artificial Intelligence |
|---|---|
| Natural intelligence | Man-made intelligence |
| Has emotions and creativity | No emotions or creativity |
| Learns from experience | Learns from data |
Artificial Intelligence is transforming the way machines work and interact with humans. It enables computers to perform intelligent tasks efficiently and accurately. Understanding AI is essential for students as it forms the foundation of future technologies such as machine learning, robotics, and data science.
