This cannot be confused. Cable is the fastest in accessing and transmitting data, but the network speed is not only determined by cable, but also depends on the bandwidth allocated to you and the service provider. Education network and telecom, netcom is not a service provider, so your optical fiber in telecom, netcom is definitely not as fast as the double-span line connected to education network, and the optical fiber is expensive, and both ends of the optical fiber need special transmission equipment.

I suggest you go to the training center of a university school to get it. It's from the Education Network. This is the case in our school. It's much faster for a school library to enter the education network than the Internet cafe, but it's not good for people who play games at school.
