Can coax connect to ethernet. Cat5 and Cat6 has 4 active wires. Coax only one?
The first Ethernet (10Base5) used a thick coax cable (0.375"). To connect to it you had to bore a hole through the jacket, shield and insulation to the center conductor. Then a "stinger" or "vampire" style connector was clamped onto the cable. Life got a lot easier when "Thin Ethernet" (10Base2) was developed which used common RG-58 (I believe) coax with BNC connectors. Later Ethernet evolved to use cat-4 twisted pair wiring. As Ethernet speeds were increased wiring specs were upgraded to cat-5 and cat-6. Note that the first Ethernet was a shared wire with lots of devices connected. Twisted pair Ehternet connections are all point-to-point wires between devices and/or hubs.
