WebNov 17, 2024 · Two LAN technologies are used today: Ethernet and wireless LANs (WLANs). Ethernet uses wired communications, including twisted-pair, fiber-optic links, and coaxial cables. Ethernet operates in the data link layer and the physical layer. It is a family of networking technologies defined in the IEEE 802.2 and 802.3 standards. WebI'm guessing that there would have been too much of a performance penalty to have to recalculate the FCS on the frame every time it hopped from one switch to the next.

This field stores a 4 bytes value that is used to check whether the received frame is intact or not. The sender device takes all fields of the frame except the FCS field, and runs them through an algorithm, known as the CRC (Cyclic Redundancy Check).
