What is the primary purpose of using a framecheck sequence (FCS) in the data link layer?a) Error correctionb) Error detectionc) Flow controld) Address resolution

A data link layer frame has the following parts EXCEPTAnswer :Frame Header: It contains the source, and the destination addresses of the frame and the control bytes.Flag: Two flags at the two ends mark the beginning and the end of the frame.   Trailer: It contains the error detection and error correction bits. Source Port: It identifies the process that sent the data.

What is the purpose of the FCS field in a frame? Group of answer choicesto determine if errors occurred in the transmission and receptionto compute the CRC header for the data fieldto obtain the MAC address of the sending nodeto verify the logical address of the sending node

What is the function of the CRC value that is found in the FCS field of a frame?to compute the checksum header for the data field in the frameto verify the integrity of the received frameto verify the logical address in the frameto verify the physical address in the frame
