The Internet, also known as the international network, refers to the huge network connected between networks. These networks are connected by a common set of protocols to form a logically single giant international network.

The Internet began with the ARPANET in the United States in 1969. Usually internet refers to the Internet in general, while Internet refers to the Internet specifically. This method of connecting computer networks to each other can be called "network interconnection". On this basis, a global Internet network covering the world called the Internet was developed, which is a network structure that is interconnected.

The Internet is not the same as the World Wide Web. The World Wide Web is just a global system based on hypertext links and is one of the services that the Internet can provide.

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.
