Getting Started with AI
Artificial intelligence (AI) is changing the way people live, work and learn. It helps answer questions recommends movies that might be fun to watch finds the way home and even unlocks phones using face recognition. Even though AI sounds like something people have probably been using it every day without knowing it.
Many people think AI is for people who write code or work with technology. The truth is, any person can understand the basics of intelligence. It is not necessary to know how to write code or have a background. Once the main ideas are understood AI becomes much easier to learn.
In terms artificial intelligence is the ability of a computer or a machine to do tasks that usually need human intelligence. These tasks include learning from information seeing patterns, understanding words solving problems and making choices. As AI keeps growing it is changing industries like healthcare, education, finance, transportation, entertainment and business. It is also creating jobs and changing the skills that will be important in the future.

What Is Artificial Intelligence?
Artificial intelligence, commonly known as AI, is a branch of computer science that focuses on creating computers and machines capable of performing tasks that usually require human intelligence. These tasks include learning from experience, recognising patterns, understanding language, solving problems, and making decisions.
Unlike traditional computer programs that simply follow a fixed set of instructions, many AI systems can learn from data and improve their performance over time. This ability allows AI to adapt to new information and handle tasks that would be difficult to solve using conventional programming alone.
A simple way to think about AI is to imagine teaching a computer how to recognise cats and dogs. Instead of writing thousands of rules for every possible image, you provide the computer with many examples. By analysing those examples, the AI system learns to identify patterns and can recognise new images it has never seen before.
Today, artificial intelligence is used in many everyday technologies. Virtual assistants answer questions, navigation apps suggest faster routes, streaming platforms recommend movies and TV shows, email services filter spam, and online stores recommend products based on your interests. In each case, AI helps computers make decisions by analysing data and recognising patterns.
As AI continues to advance, it is becoming one of the most important technologies of the modern world. It is transforming industries, improving productivity, supporting scientific research, and creating new opportunities for businesses, students, and professionals.
How Does Artificial Intelligence Work?
Artificial intelligence works by collecting data learning from it and using that knowledge to make predictions or decisions. Of simply following a fixed set of instructions AI systems analyse large amounts of information to recognise patterns and improve their performance over time. Although the technology behind AI can be complex the basic process is easy to understand. Most AI systems follow the five steps.
Collecting Data
Everything begins with data. AI learns from examples just as people learn through experience. The relevant and high-quality data an AI system receives the better it can understand patterns and make accurate predictions. For example an AI model that recognises cats and dogs needs thousands of labelled images to learn the differences between the two animals.
Learning Patterns
After collecting data the AI system analyses it to identify patterns and relationships. This learning process is called machine learning, where algorithms examine the data and discover how different pieces of information are connected without being programmed for every situation.
Training the Model
Once the patterns have been identified the AI system enters the training stage. During training the model repeatedly processes the data compares its predictions with the answers and adjusts itself to improve accuracy. This process may continue thousands or even millions of times until the model performs well.
Making Predictions or Decisions
After training is complete the AI model can analyse information that it has never seen before. Based on what it has learned it predicts outcomes answers questions recognises images translates languages or recommends products and content. For example when you ask ChatGPT a question or receive a movie recommendation on Netflix AI is using patterns learned during training to generate a response.
Improving Over Time
Many modern AI systems continue to improve by learning from data and user feedback. As more information becomes available developers can retrain the model to make it more accurate, reliable and useful, in real-world situations.
Types of Artificial Intelligence
Artificial intelligence is not one thing. It is made up of different types of Artificial Intelligence that are made for different things. Some Artificial Intelligence systems can only do one thing while others can do a lot of things. Knowing about these types of Artificial Intelligence helps us see how Artificial Intelligence is used in our lives and where Artificial Intelligence is going in the future.
Nowadays most Artificial Intelligence that we use belongs to a group called Narrow Artificial Intelligence. This type of Artificial Intelligence is made to do things like understand what we are saying suggest movies we might like or answer our questions. People who study Artificial Intelligence are also trying to make advanced types of Artificial Intelligence but we do not see them being used yet.
Here are the four main types of Artificial Intelligence that people talk about :
Reactive Machines
Reactive machines are the basic kind of artificial intelligence. They look at what’s happening now and react to it but they do not remember what happened before or use that to get better. A good example is IBMs Deep Blue, the computer that plays chess and beat the world champion Garry Kasparov in 1997. It could think about a lot of chess moves but it could not remember what it did before or get better at chess after each game. Example :
IBM Deep Blue : Basic chess programs that play chess like IBM Deep Blue do not remember what happened before they just play chess based on what they see. Reactive machines like these are good, at doing one thing. They do not learn from Reactive machines like them.
Limited Memory AI
Limited Memory AI is a type of Limited Memory AI that can remember things from the past for a while. It uses this information to make choices. This kind of Limited Memory AI is used a lot nowadays. A lot of things use Limited Memory AI, like cars that drive themselves systems that tell you what you might like and helpers that talk to you. They look at what happened to make good decisions. Examples : Google Maps , ChatGPT ,The recommendations you get from Netflix , Siri and Google Assistant use Limited Memory AI too.
Theory of Mind AI
Theory of Mind AI is an idea, for artificial intelligence systems that could understand how humans feel what humans want to do what humans believe in and how humans interact with each other. Theory of Mind AI is something that scientists are still trying to figure out. Although, scientists are still studying Theory of Mind AI there is no Theory of Mind AI that exists today.
Self-Aware AI
Self-Aware AI is a kind of intelligence that would be able to think for itself know how it feels and have its own thoughts and emotions like people do. Self-Aware AI would be able to think and feel things on its own like humans do. At present Self-Aware AI only exists in stories and ideas not, in life. Scientists have not been able to make a machine that’s truly Self-Aware AI. They have not created a Self- AI that can think and feel like a human being.
Real-Life Examples of Artificial Intelligence
You might not know this. Artificial intelligence is already a big part of the things you do every day. Artificial intelligence is there when you wake up and start using your phone. It is even there when you watch a movie at night. Artificial intelligence helps make a lot of the things you use work better. These systems look at data find patterns and make choices to make things faster and more personalised for you. Here are some examples of intelligence, in everyday life.
Virtual Assistants
Virtual assistants are really helpful. They use intelligence to understand what we say answer our questions remind us of things play music and do lots of other things when we tell them to.
Example : Siri , Google Assistant , Amazon Alexa , AI Chatbots
AI Chatbots
AI chatbots can understand questions. Create responses that sound like they came from a person. They are commonly used for customer support, education, content creation, programming help and research.
Examples : ChatGPT , Microsoft Copilot , Google Gemini .
Recommendation Systems
When you use streaming platforms and online stores they use computers to figure out what you like and what you have done before. Then they suggest things they think you will like.
Examples: Netflix tells you what movies you might want to watch , YouTube suggests videos you might want to see , Spotify recommends music it thinks you will like , Amazon tells you what products you might want to buy based on what you have looked at and what you have bought from Amazon before. Recommendation Systems are used by these websites to do this.
Navigation Apps
When you use navigation apps they look at what’s happening on the roads right now like traffic and road closures and they also look at where you have been before. They use all this information to tell you which way to go to get to your destination the fastest.
Examples : Google Maps , Waz , Apple Maps.
Facial Recognition
Facial recognition uses AI to identify or verify a person’s identity by analysing facial feature.
Examples : Apple Face ID , Android Face Unlock.
