What is Artificial Intelligence (AI) and How Does It Work?
These days, we often hear that the time for AI has arrived. AI will take away everyone's jobs, that AI has made many things easier and will make many more easier in the future. AI is this, that, and who knows what else. We hear many different opinions about AI.
But what exactly is AI? Let's understand it.
AI is a new-age technology that makes computers or machines "intelligent," enabling them to operate on their own, eliminating the need for humans to repeatedly instruct them.
AI stands for Artificial Intelligence (artificial intelligence means artificial or man-made, not natural). Artificial intelligence refers to artificial intelligence created by humans to make computers and machines perform better than they already do. Overall, it's a technology that enables machines to understand, learn, and make decisions like humans.
Let's understand this with some examples:
When you talk to "Google Assistant" or "Siri" on your phone, they make your work easier.

These and many other things are possible because of AI.
Main Types of AI - Based on the capabilities of AI, it is divided into three main types:
1. Narrow or Limited AI - This is an AI system designed to perform a single, specific task.
Examples: Google Translate for translating any language; Face Recognition for facial recognition; Chatbots for customer support.
These are highly accurate and precise, but they are limited to the single task for which they were created. For example, you can't use Google Translate for anything other than translation.
2. General AI - This type of AI is not yet fully developed. This type of AI is said to have the ability to act and make decisions like humans. It will be able to learn and make decisions about any object or subject just like humans do.
Example - If a robot is equipped with simple AI, it will be able to study, cook, and even talk.
3. Super AI (Super Artificial Intelligence) - This is the AI of the future, which will be more intelligent than humans because it will be so capable of learning new things on its own and making decisions better than humans. However, this has only been imagined and research is ongoing.
Example: The robots shown in the Bollywood film Robot and the Hollywood film Iron Man are based on the concept of Super AI.
How does AI work?
The way AI works is based on three main components:
1. Data - The AI system is first given a large amount of data, which can be of all types, such as images, videos, voice, or text.
Example - If I want an AI to recognize a picture of an elephant, I would show it thousands of pictures of elephants of all types.
2. Machine learning – This process is called the brain of AI. In this process, AI learns patterns from data and makes predictions, much like a child learns that apples are red by looking at a red apple.
3. Algorithms - Algorithms are rules or formulas designed to help AI make decisions. Algorithms determine how AI solves a problem.
If we look at AI's work simply, then:
Data + Machine Learning + Algorithms = Artificial Intelligence
