Hello, everyone, it's time to study everyday. Today we come to talk about the difference between Ethernet, LAN, and the Internet.
Ethernet is a kind of local area network, but LAN is not necessarily Ethernet, but because most of the current local area networks are Ethernet, so generally speaking, LAN, everyone defaults to Ethernet.
The so-called Ethernet is a bus-type LAN, created by Xerox Corporation. There are many ways to implement the LAN topology, such as star, ring, and bus. However, with years of experience, Ethernet, which is the bus type, is the most successful and the most widely used.
Digression: It is because of the successful promotion of Ethernet that the TCP/IP protocol it supports is then becoming the actual standard that is more than a standard application, although it is not a standard.
Ethernet, Internet These are two different concepts. For example, the Internet, WAN, and LAN can be categorized into regions and regions. The Ethernet Ethernet, ATM network, and FDDI network can be counted as one class, classified according to transmission technology, and belong to the data link layer of the OSI reference type.
Ethernet is very popular. Ethernet interfaces on computers, Wi-Fi interfaces, Gigabit Ethernet switches, 10 Gigabit Ethernet ports, and network cables are all components of Ethernet. Ethernet can be used. In LANs, WANs, and also on the Internet, there is now a trend towards Ethernet, which is easy to use, resulting in popularity, and then it is well studied, 10 MB, 100 MB, 1000 MB, 10 GB ... This is its rate upgrade. The Internet is a general term for networks connected by operators and companies, organizations, and users. It contains Ethernet, ATM networks, and other interfaces such as E1/E3.
The main difference: Ethernet is a local area network that can only connect to nearby devices. The Internet is a wide area network. We can connect to the United States via the Internet to get news.
Both are considered networks used to connect computers, but the scope of the two is different. Ethernet is limited to a certain distance. We can have hundreds of Ethernets. However, the Internet is the largest wide-area network. We only have one Internet, so the Internet can be regarded as a network.
The Internet is a large, international system that can connect networks in various parts of the world. Private, public, academic or commercial networks, or government networks can all connect and share resources. Imageically speaking, the Internet is the network we use to open web pages, send e-mails, and listen to music online. It includes a very wide range of information, and now we are used to it.
Ethernet, on the other hand, basically allows only a few local computers to connect to each other. There is a set of technical support for sending messages between computers. In general, the computers connected to the Ethernet are in the same building or near the surroundings. However, with the development of Ethernet cable, the range of Ethernet can be extended to ten kilometers. However, because they are interconnected by network cables, it is unrealistic to connect to remote locations.
In life, Ethernet is to connect your computer and laptop to your cat, and then connect to the Internet through the cat so that you can Skype with foreign friends. Therefore, your home's computers, laptops, and cats form an Ethernet network. As you can imagine, there are thousands of Ethernet networks in the world. Business Ethernet is used to connect all of their computers to the main server.
Ethernet can have one or more administrators. Some parts of the Internet may be managed by administrators, but there is no single administrator who can control the entire Internet.
Another difference is security. Ethernet is more secure because it is a closed internal network and outsiders do not have permission. But the Internet is openly connected and everyone can browse.
