Networking Basics You MUST Know for System Design | OSI, HTTP, TCP vs UDP | 3 Way Handshake

Networking Basics for System Design & HLD — HLD Series Before jumping into System Design, you need to understand the fundamentals of Computer Networking. In this video, we cover the most important networking concepts you need for High-Level Design (HLD) and System Design interviews. In this video, you'll learn: OSI Model — What are the 7 layers and what does each layer do? HTTP Protocol — How HTTP requests and responses work HTTP Methods — GET, POST, PUT, DELETE and when to use them HTTP Status Codes — 1xx, 2xx, 4xx and 5xx with practical examples TCP 3-Way Handshake — SYN, SYN-ACK and ACK explained TCP vs UDP — Key differences and when to use each How these networking concepts are relevant to System Design This video is designed to give you a strong networking foundation before moving into advanced HLD and System Design concepts. If you're preparing for FAANG/SDE interviews, learning System Design, or simply want to understand how systems communicate over the network, this video is a great place to start. Topics Covered OSI Model | HTTP | HTTP Methods | HTTP Status Codes | TCP | UDP | 3-Way Handshake | Computer Networks | System Design | HLD This is part of my System Design / HLD Series, where we start from the fundamentals and gradually move toward designing real-world scalable systems.
