5 Questions
What are the duties of the Data Link Layer?
The duties of the Data Link Layer include managing the LLC and MAC sublayers, implementing error detection and correction, controlling data link protocols, handling multiple access in LANs, managing wireless LANs, and facilitating switching.
What are the different types of errors that can occur during data transmission?
The different types of errors that can occur during data transmission are single-bit errors and burst errors.
Explain the concept of burst error and provide an example of its length.
A burst error means that 2 or more bits in the data unit have changed. An example of a burst error of length 5 would be when 5 consecutive bits in the data unit are altered.
What are the methods used for error detection in the Data Link Layer?
The methods used for error detection in the Data Link Layer include parity check, cyclic redundancy check (CRC), and checksum.
How does error detection use the concept of redundancy, and what are the redundancy detection methods?
Error detection uses the concept of redundancy by adding extra bits for detecting errors at the destination. The redundancy detection methods include the even-parity concept and techniques like parity check, CRC, and checksum.
Test your knowledge on the design issues, error control methods, flow control protocols, medium access control sublayer protocols, Ethernet and Wireless LANs, and Bluetooth related to the data link layer.
