Study Notes
Primary Function of the Transport Layer
- Manages end-to-end communication between devices across a network.
- Ensures reliable data transfer by providing error detection and recovery.
Services Provided by Transport Layer Protocols
- Offers flow control to manage the rate of data transmission, preventing congestion.
- Facilitates segmentation and reassembly of large messages into manageable packets.
Differences Between Transport Layer and Data Link Layer
- Transport layer operates at a broader level, providing services to applications across networks, while data link layer manages communications between directly connected devices on the same network.
- Transport layer is concerned with end-to-end delivery, while the data link layer deals with physical addresses and control of physical media.
Ultimate Goal of the Transport Layer
- To ensure reliable and efficient data transmission between devices, ultimately delivering data accurately and in the correct order.
Entities Dealt with by the Transport Layer
- Interacts with application layer protocols to facilitate communication between different software applications.
- Engages with the network layer to transmit segments to the destination host effectively.

Description
Test your knowledge on the core of the OSI model - the transport layer. This layer oversees the delivery of data between application programs on different devices and acts as a liaison between upper-layer and lower-layer protocols.
