What is the fixed header length of an Ethernet frame?

Explanation:
Ethernet frames have a fixed header length of 14 bytes. This header is made up of the destination MAC address (6 bytes), the source MAC address (6 bytes), and the EtherType/length field (2 bytes). The preamble and start-of-frame delimiter belong to the physical layer and are not part of the frame header, while the 4-byte Frame Check Sequence is a trailer, not the header. The payload size can vary, but the header length stays constant at 14 bytes.
