File Uploading in Node.js: Multer with Postman (Single & Multiple Images) part1
🚀 Welcome to the ultimate guide on uploading files in Node.js and Express using Multer!
In this video, we break down how file uploads actually work behind the scenes, how data is broken into chunks, and the core differences between TCP and UDP when handling network traffic. Then, we dive straight into the code to implement both Single and Multiple image uploads using Multer and test them live using Postman!

🧠 QUICK OVERVIEW:
TCP (Transmission Control Protocol): Reliable, connection-oriented, guarantees all your image chunks arrive perfectly without data loss.
UDP (User Datagram Protocol): Fast, connectionless, great for live streaming but might drop packets (bad for file uploads).
Chunks: Large files are broken down into small packets/chunks of binary data stream across the network, which Multer reassembles onto your server.
