Which lan switching mode begins switching after reading only the first 64 bytes of the frame?

The LAN switching mode that begins switching after reading only the first 64 bytes of the frame is known as "cut-through switching." In this mode, the switch starts forwarding the frame as soon as it reads the destination MAC address, allowing for lower latency compared to store-and-forward switching, which waits for the entire frame to be received and checked for errors before forwarding. This method is beneficial in environments where speed is critical.
