09/20: Layer 4 – The Transport Layer: TCP, UDP & Reliable Delivery
The Transport Layer (Layer 4) is crucial for managing end-to-end communication between applications on different devices. It ensures data is delivered reliably and accurately, using protocols like TCP and UDP to meet varying needs for speed and reliability. Understanding the functions of the Transport Layer, including segmentation, error recovery, and flow control, is essential for effective networking.
- ▪The Transport Layer determines how data is delivered between applications on different devices.
- ▪TCP provides reliable, connection-oriented communication, while UDP offers fast, connectionless communication.
- ▪TCP uses a Three-Way Handshake to establish connections and ensures data integrity through sequence numbers and acknowledgments.
