Question: In the OSI model, which layer is responsible for error detection and correction?

Options:

Correct Answer: Data Link Layer

Solution:

The Data Link Layer (Layer 2) is responsible for error detection and correction to ensure reliable data transfer.

In the OSI model, which layer is responsible for error detection and correction?

In the OSI model, which layer is responsible for error detection and correction?

Step 1: Understand the OSI model, which has 7 layers that help in network communication.
Step 2: Identify the layers of the OSI model, which are: Application, Presentation, Session, Transport, Network, Data Link, and Physical.
Step 3: Focus on the Data Link Layer, which is Layer 2 in the OSI model.
Step 4: Learn that the Data Link Layer is responsible for ensuring that data is transferred correctly between devices on the same network.
Step 5: Recognize that error detection means finding mistakes in the data, and error correction means fixing those mistakes.
Step 6: Conclude that the Data Link Layer handles both error detection and correction to provide reliable communication.

Data Link Layer – The second layer of the OSI model that handles error detection and correction for reliable data transfer.
OSI Model – A conceptual framework used to understand network interactions in seven layers.
