In this class we covered what programming languages are and how they work behind the scenes.

1. What is a Programming Language?
A programming language is a way for humans to communicate with computers.
Jaisay humans Urdu/English mein baat karte hain, computer Python, C, Java, etc. ko samajhta hai.
Language → Instructions → Computer executes.

2. Why Do We Need It?
Computer khud se samajh nahi sakta.
Usay sirf binary (0 & 1) samajh aati hai.
Programming language bridge ki tarah kaam karti hai.

3. High-Level vs Low-Level Languages
High-Level (Python, JavaScript): Human friendly, easy to learn, readable.
Low-Level (Assembly, Machine): Hardware ke qareeb, fast, performance oriented.

4. Behind The Scenes – How Code Runs
User code → Compiler/Interpreter → Machine Code → CPU executes.
Example (Python):
print("Hello") → Interpreter → Machine Instructions → CPU → Output.

5. Compiler vs Interpreter
Compiler: Pura code aik baar translate karta hai.
Interpreter: Code line-by-line run karta hai.
Python interpreter-based language hai.

6. Machine / Binary Code
Machine sirf 0 aur 1 samajhti hai.
Code convert hota hai → CPU execute karta hai.
Example: 01001010 01011010
Human ke liye mushkil — machine ke liye normal.

7. Why Python?
Easy syntax
High demand
Used in:
✔ AI / Machine Learning
✔ Web Development
✔ Data Science
✔ Automation
✔ Scripting

Teacher Tip (by Laraib Nawaz):
“Programming language computer ka dimaag nahi — balkay usse baat karne ka zariya hai.”
