What is a network? What are the relevant naming of the network and its application mode? This article will briefly introduce it.

Network related fate
The relationship between the Internet, the Internet, and the World Wide Web is: the Internet includes the Internet, and the Internet includes the World Wide Web. Any network composed of devices that can communicate with each other is called the Internet. So, even if there are only two machines, no matter what technology is used to communicate with each other, it is called the Internet.
The international standard way of writing the Internet is Internet, and the Internet is a type of Internet. The Internet is not just an Internet of two machines, it is an Internet of tens of millions of devices.
The Internet uses the TCP/IP protocol to allow different devices to communicate with each other. However, the network using the TCP/IP protocol is not necessarily the Internet. A local area network can also use the TCP/IP protocol.
To determine whether you are accessing the Internet, first check whether your computer has the TCP/IP protocol installed. Secondly, check whether you have a public network address (the so-called public network address refers to all addresses other than private network addresses).
The Internet is implemented based on the TCP/IP protocol. The TCP/IP protocol consists of many protocols, and different types of protocols are placed in different layers. Among them, there are many protocols located at the application layer. For example FTP, HTTP, SMTP. As long as the application layer uses the HTTP protocol, it is called World Wide Web.
The reason why when you enter the Baidu URL in the browser, you can see the web pages provided by Baidu. It is because the HTTP protocol is used to communicate between your personal browser and Baidu's server.
Network application model
At the first level, Internet application models can be divided into e-government application models, e-commerce application models, network information acquisition application models, network communication interactive application models, and network entertainment application models.
Network information acquisition application modes can be subdivided into:
Online news model, search engine model, information classification model, information aggregation model and knowledge sharing model
E-commerce application models are subdivided into B2B e-commerce model, B2C e-commerce model, C2C e-commerce model and O2O e-commerce model.
Network communication and interaction application modes are subdivided into:
Instant messaging mode, personal space mode, online social mode, online forum mode
Online entertainment application models are subdivided into online game models, online literature models, and online video models.
