Questions & Step-by-Step Solutions
In which OSI layer does error detection and correction primarily occur?
Step 1: Understand the OSI model, which has 7 layers that describe how data is transmitted over a network.
Step 2: Identify the layers of the OSI model: 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 node-to-node data transfer and error detection.
Step 5: Recognize that error detection and correction methods, such as checksums and CRC (Cyclic Redundancy Check), are used at this layer to ensure data integrity.
Step 6: Conclude that error detection and correction primarily occur at the Data Link Layer.
