What is the Internet?
The Internet is a collection of global information resources. There is a rough saying that INTERNET is a logical network formed by the interconnection of many small networks (subnets), and each subnet is connected to several computers (hosts). The Internet aims to exchange information resources with each other, is based on some common protocols, and is formed through many routers and the public Internet. It is a collection of information resources and resource sharing.
The Internet is a wide area network.
Introduction to network types:
1. Local area network (LAN): Generally limited to a small area, less than 10km, usually connected by wire;
2. Metropolitan Area Network (MAN): The scale is limited to a city, an area of 10 to 100km;
3. Wide Area Network (WAN): The network spans national boundaries, continental boundaries, and even the world scope.
LAN and WAN are the hot spots of the network. The local area network is the basis for the other two types of networks, and the metropolitan area network is generally added to the wide area network. The typical representative of WAN is the Internet.
