1. The school network is a local area network, also known as an intranet. The online resources are all controlled by the school, and some resources, such as library resources, cannot be accessed from outside the school. Because students are mainly used for learning, it is called education network. Of course, if your school only allows you to access the education network ending in edu.cn, it is possible, but it is unlikely. In short, your internet access at school is controlled by the school.

2. Public access, also known as extranet, is not controlled by local area. If you surf the Internet through telecom or Netcom at home, it is a public network.

Supplement:

Judging from your supplement, you use a local area network, which is slow because the capacity of key equipment in the school is not enough, and there is no way to solve it unless the school invests in increasing capacity.
