Detailed Solution
Download Solution PDFThe correct answer is Transport layer.
Key Points
- The Transport layer is responsible for process-to-process delivery of the entire message.
- This layer ensures that data is transferred from one process to another reliably and without errors.
- It manages the establishment, maintenance, and termination of the logical connection between the two communicating hosts.
- The Transport layer protocols include TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).
- TCP provides reliable, connection-oriented service, ensuring that data is delivered in the correct order and without errors.
- UDP provides a connectionless service with minimal error recovery features, making it faster but less reliable than TCP.
Additional Information
- The Transport layer also handles flow control, ensuring that a sender does not overwhelm a receiver with too much data at once.It is responsible for multiplexing and demultiplexing of data, meaning it can handle multiple communication streams at the same time.
- The Transport layer can provide error detection and correction mechanisms to ensure data integrity.
- Port numbers are used at the Transport layer to identify different processes or services running on the same device.
- This layer also provides mechanisms for congestion control to manage network traffic and avoid congestion.
