Question: What layer of the OSI model is responsible for end-to-end communication and error recovery?

Options:

Correct Answer: Transport Layer

Solution:

The Transport Layer (Layer 4) is responsible for end-to-end communication and error recovery, ensuring complete data transfer.

What layer of the OSI model is responsible for end-to-end communication and error recovery?

What layer of the OSI model is responsible for end-to-end communication and error recovery?

Step 1: Understand the OSI model, which has 7 layers that help in network communication.
Step 2: Identify the layers: Layer 1 is Physical, Layer 2 is Data Link, Layer 3 is Network, Layer 4 is Transport, Layer 5 is Session, Layer 6 is Presentation, and Layer 7 is Application.
Step 3: Focus on Layer 4, which is the Transport Layer.
Step 4: Learn that the Transport Layer is responsible for end-to-end communication, meaning it ensures data is sent from the sender to the receiver.
Step 5: Recognize that the Transport Layer also handles error recovery, which means it checks if the data was received correctly and can resend it if there are errors.
Step 6: Conclude that the Transport Layer (Layer 4) is the correct answer to the question.
