22Which switching method uses the CRC value in a frame?fragment-freestore-and-forwardcut-throughfast-forward
Solution
The switching method that uses the CRC value in a frame is the "store-and-forward" method.
Here's a step-by-step explanation:
-
In the store-and-forward switching method, the switch waits for the entire frame to be received.
-
Once the frame is received, the switch checks the Cyclic Redundancy Check (CRC) value to ensure that the frame is not corrupted.
-
The CRC is a type of hash function that detects accidental changes to raw data. It's used in networks to detect errors in the frames.
-
If the frame is not corrupted, the switch then forwards the frame to its destination.
-
If the frame is corrupted, the switch discards it.
So, the store-and-forward switching method uses the CRC value in a frame to ensure data integrity.
