What is the size of the Type field in the Ethernet header?

The Type field in the Ethernet header is indeed 2 bytes in size. This field is crucial because it indicates the protocol encapsulated in the payload of the Ethernet frame. For instance, common values include 0x0800 for IPv4 and 0x0806 for ARP. By providing this information, devices receiving the Ethernet frame can correctly process the information according to the specified protocol, which is essential for the interoperability of networking technologies. Understanding the structure of the Ethernet frame, including the Type field, is fundamental in networking, particularly for troubleshooting and designing networks that support various protocols.
