    - FCS (Frame Check Sequence) is an error-detecting code added to a frame in a communication protocol.

    - Frames are used to send upper-layer data from a source to destination.

    - FCS is not an error recovery process.

    How FCS used?

            - When data is transmitted in a frame, a specific FCS is added to the frame's data bits.

            - The source calculates this FCS prior to sending a frame, which is verified and compared at the destination.

            - If the FCS data matches, the transmission is considered successful. If not, the data frame is automatically discarded due to an error.
