The Internet refers to a huge network of networks connected in series. These networks are connected by a set of common protocols (TCP/IP protocol, a computer language) to form a logically single huge international network. This method of connecting computer networks to each other can be called "network interconnection". On this basis, a global Internet covering the whole world is developed, called the Internet. The Internet is to include computers all over the world in one network to achieve data exchange.

Domestic network operators have built networks so that people can access the Internet and upload and download in their daily lives. The upload and download traffic generated in the process of uploading and downloading uses the network system built by the operator. Therefore, we need to pay a certain amount of network fees to the operator when we go online. The people here include ordinary people and major companies that need the Internet.
