Computer network types generally include: local area network, metropolitan area network, wide area network and the Internet. So what are the connections and differences between them? This article will tell you one by one.

Q1: Ethernet is a kind of local area network, but LAN is not necessarily Ethernet. However, because most of the current LANs are Ethernet, generally speaking of LAN, everyone defaults to Ethernet.
The so-called Ethernet is a bus-type local area network. There are many implementation methods of LAN topology, including star, ring, bus, etc.
Generally speaking, the bus type of Ethernet is the most successful and widely used.
Q2: Ethernet and the Internet are two different concepts.
Give some examples. Give some examples. If classified according to region and scope. Internet, WAN, and LAN are one category.
If classified according to transmission technology. Ethernet, ATM network, and FDDI network are one category. These belong to the OSI reference type data link layer.
Ethernet is very popular. On the computer: Ethernet port, Wi-Fi port, Gigabit, 10 Gigabit Ethernet ports on Ethernet switches, routers, and network cables. They are all part of Ethernet.
On LAN, WAN, Internet. Can use Ethernet. Nowadays, the network has a trend of Ethernet.
There is a trend of Ethernetization in the network. Because it is easy to use, it is very popular. Then you can easily study, 10 MB bandwidth, 100 MB, 1000 MB, 10 MB.
The general term for networks connected by large and small operators, companies, institutions, and users - the Internet. It includes Ethernet, ATM network, and other interfaces.
Q3: The main difference: Ethernet is a local area network that can only connect nearby devices. The Internet is a wide area network. We can get the news via internet connection.
Both can connect to computer networks, but their ranges are different. We can have thousands or hundreds of Ethernets; but the Internet is the largest wide area network.
Private, public, academic, commercial or government networks can connect to each other and share resources. What is the Internet? simply put. The Internet is the network we use to open web pages, send emails, and watch movies online.
The Internet contains a very wide range of information, which we have now taken for granted.
What is Ethernet? Ethernet is basically a type of computer network that only allows a few local computers to connect to each other. There is a set of technical support for computers to send messages to each other. Generally speaking, computers connected to an Ethernet network are in the same building or nearby.
But with the development of Ethernet cables. The development of Ethernet network cables can extend the range of Ethernet to ten kilometers. It is not practical to connect Ethernet to far away places. Because Ethernet uses network cables to realize interconnection.
An Ethernet can have one or several administrators. Administrators can control certain parts of the Internet. But controlling the entire Internet with one administrator? This is currently unrealistic!
That’s it for a brief description of the main differences between computer network types.
