In an Ethernet frame, FCS stands for "Frame Check Sequence". It is a four-octet field used to verify that the frame was received without loss or error. The method used for verification is known as a Cyclic Redundancy Check (CRC).

The Ethernet (II) frame uses the Frame Check Sequence (FCS) field for error detection. This field is a 4-byte cyclic redundancy check (CRC) value that is calculated based on the frame's contents before transmission. When the frame is received, the receiving device calculates the CRC again and compares it to the FCS value; if they do not match, an error is detected, indicating that the frame may have been corrupted during transmission.
