A brief history of Ethernet over traditional Ethernet:

In 1972, Robert Metcalfe and colleagues at Xerox PARC developed the world's first experimental Ethernet system for interconnecting the Xerox Alto, a personal workstation with a graphical user interface.

The experimental Ethernet was used to interconnect Alto workstations, servers, and laser printers at a data rate of 2.94 Mbps.

Metcalfe's experimental network was known as the Alto Aloha Network, which he named Ethernet in 1973, noting that it could support any type of computer in addition to Alto workstations, and that the entire network could be used by any type of computer. In 1973, Metcalfe named it Ethernet, noting that the system could support any type of computer, in addition to Alto workstations, and that the entire network architecture went beyond the Aloha system. He chose the term "ether" to characterize the network: a physical medium (such as a cable) carries a stream of bits to each site, as the ancient "luminiferous ether" (ether) theory explains. The ancient "ether theory" states that the "ether" fills the entire space by means of electromagnetic waves. Thus, Ethernet was born.

The original Ethernet was an experimental network of coaxial cables with CSMA/CD conflict detection. The success of this network attracted attention, and in 1980, three companies (Digital Equipment Corporation, Intel Corporation, and Xerox Corporation) jointly developed the 10M Ethernet 1.0 specification. The original IEEE 802.3 was based on this specification and was very similar to it.The 802.3 Working Group adopted the draft in 1983 and published the official standard ANSI/IEEE Std 802.3-1985 in 1985.Since then, as the technology has evolved, the standard has been heavily supplemented and updated to support more transmission media, higher transmission rates, etc.

In 1979, Metcalfe founded 3Com and produced the first usable network device: the Ethernet card (NIC), the first product to allow disparate devices, from mainframes to IBM terminals and PCs, to communicate seamlessly with each other, enabling organizations to seamlessly ****enjoy and print files, thereby enhancing productivity and improving enterprise-wide communication capabilities.
