The internal connection of education network refers to the connection of computers in the network designated by him, which can be accessed at high speed, but the network outside this range cannot be connected to this internal.

Education network is a proprietary network, and the service providers are different. Just like the telephone we use, it is divided into Netcom, Telecom and Tietong.

Therefore, other networks, such as Netcom and Telecom, are not educational networks, so they are called non-educational networks.
