🌐 Layer 4: Transport Layer (OSI Model)
How does data get broken down, managed, and delivered reliably between apps? Through the Transport Layer.
Here are the key points:
🔹 1. What is it?
The 4th layer of the OSI model. It handles end-to-end communication and data delivery.
🔹 2. Core Functions
Segmentation: Splits large files into smaller segments.
Flow & Error Control: Manages transmission speed and recovers lost data.
🔹 3. TCP vs. UDP Protocols
TCP: Connection-oriented, highly reliable, and guarantees delivery (for web, chat, banking).
UDP: Connectionless, ultra-fast, but no delivery guarantee (for live streaming, gaming).
🚀 Just like a logistics manager packs and tracks cargo, the Transport Layer organizes and secures your data stream!
