What is the primary function of the data-link layer?
Understand the Problem
The question is asking about the primary function of the data-link layer in the context of computer networking, specifically its role in terms of data encapsulation and communication between devices.
Answer
Facilitate reliable data transfer between adjacent network nodes.
The primary function of the data link layer is to facilitate reliable data transfer between adjacent network nodes by framing and error detection, ensuring node-to-node delivery of data.
Answer for screen readers
The primary function of the data link layer is to facilitate reliable data transfer between adjacent network nodes by framing and error detection, ensuring node-to-node delivery of data.
More Information
The data link layer is critical in the OSI model, providing framing and error management to ensure data integrity and efficient communication between nodes.
Tips
A common mistake is confusing the data link layer with the network layer. The data link layer is responsible for node-to-node transfer, while the network layer handles data routing between nodes.
