Networking in High-Level Design

📌 Key Concepts:​

Two important communication models:

  1. OSI Model
  2. TCP/IP Model

🔧 Focus in HLD (High-Level Design):​

In the TCP/IP Model, the two most critical layers for system design are:

  1. Application Layer
  2. Transport Layer

Network Models

  • OSI Model (7 Layers): Conceptual, with each layer handling specific functions.
  • TCP/IP Model (4 Layers): Practical, simplified model focusing on internet communication.
