Osi Model Questions
The function of error detection and correction in the Data Link layer of the OSI Model is to ensure the integrity of data transmission over a physical link. It involves the use of error detection codes, such as checksums or cyclic redundancy checks (CRC), which are added to the data before transmission. These codes allow the receiving device to detect and correct any errors that may have occurred during transmission. If an error is detected, the receiving device can request the sender to retransmit the data. This process helps to ensure that the data is accurately and reliably transmitted between devices.
