The Big Question
Let us ask you something directly.
You are starting your journey into tech. You read articles, watch videos, and listen to podcasts. But you keep running into terms you do not understand. You feel like you are missing half of what is being discussed. You think to yourself: "How do I learn all this vocabulary? Where do I even start?"
We hear this question every week from students who visit our center near Pitampura Metro.
Here is the honest answer: You do not need to learn all the terms at once. Start with the most common ones. Use them in conversations. Ask questions when you do not understand. The vocabulary will come with practice—just like learning any new skill.
Step 3: AI and Machine Learning Terms
1. Artificial Intelligence (AI)
The simulation of human intelligence in machines. AI systems can perform tasks that normally require human intelligence, such as visual perception, speech recognition, decision-making, and language translation.
Example: ChatGPT is an AI that can understand and generate human-like text.
2. Machine Learning (ML)
A subset of AI where systems learn from data without being explicitly programmed. Instead of following fixed rules, ML models identify patterns in data and make predictions or decisions.
Example: Netflix uses ML to recommend shows based on what you have watched.
3. Deep Learning
A type of machine learning inspired by the structure of the human brain. Deep learning uses neural networks with many layers (hence "deep") to process data and learn complex patterns.
Example: Deep learning powers self-driving cars by analyzing camera footage to identify pedestrians and obstacles.
4. Neural Network
A computing system inspired by the human brain. Neural networks consist of layers of interconnected nodes (like neurons) that process information and learn from data.
Example: Neural networks are the foundation of modern AI, used in everything from image recognition to language translation.
5. Natural Language Processing (NLP)
The ability of computers to understand, interpret, and generate human language. NLP is what makes chatbots, translation services, and voice assistants work.
Example: Google Translate uses NLP to convert text between languages.
6. Large Language Model (LLM)
A type of AI model trained on massive amounts of text data to understand and generate human-like language. LLMs power tools like ChatGPT, Claude, and Gemini.
Example: ChatGPT is powered by an LLM that can write essays, answer questions, and generate code.
7. Generative AI
AI that can create new content—text, images, music, video, or code—rather than just analyzing existing data.
Example: Midjourney generates images from text descriptions. ChatGPT generates text.
8. Prompt Engineering
The practice of designing effective inputs (prompts) for AI models to get the desired output. It is a skill that combines understanding of how AI works with clear communication.
Example: Instead of asking "Tell me about India," a well-crafted prompt might be "Write a 200-word summary of India's history, culture, and economy, formatted in bullet points."
9. Hallucination
When an AI generates information that sounds plausible but is factually incorrect or entirely made up. Hallucination is a key challenge in AI safety.
Example: An AI might invent a source or quote when asked for a citation.
10. RAG (Retrieval-Augmented Generation)
A technique that combines AI generation with a retrieval system, allowing the AI to pull in up-to-date information from external sources before generating a response. RAG helps reduce hallucinations.
Example: Instead of guessing current stock prices, a RAG system retrieves the latest market data.
11. Embedding
A numerical representation of text, images, or other data that captures its meaning. Embeddings allow computers to process and compare semantic information.
Example: "Apple" and "Fruit" have different embeddings that capture their relationship in language.
Step 4: Programming and Development Terms
12. API (Application Programming Interface)
A set of rules that allows different software applications to communicate with each other. APIs define how requests and responses should be formatted.
Example: When you book a flight online, the travel website uses an API to get real-time availability from the airline.
13. Version Control
