NO. CAT2, 3 and 4 were NOT Ethernet. Ethernet was first deployed on a thick yellow coax cable (10BASE5), then later a thinner RG58 coax (10BASE2) and only after that were CAT5 twisted pairs used (10BASE-T) Source: Me working many years in computer networking including 5 years at Xerox PARC, where Ethernet was invented.
Great video. Very interesting. Subscribed.
