Difference between Ethernet and Broadband [Copy link]

Ethernet connection: Local connection only appears in Microsoft Windows XP/7 operating system. In Windows 8/8.1 system, local connection is renamed "Ethernet". Both "Local Connection" and "Ethernet" actually reflect the physical network card (network adapter) on the computer. Ethernet is the most common communication protocol standard used in existing local area networks today. It was established in the early 1970s. Ethernet is a commonly used local area network (LAN) standard with a transmission rate of 10Mbps. In Ethernet, all computers are connected to a coaxial cable, using the carrier sense multiple access with collision detection (CSMA/CD) method, a competition mechanism and a bus topology structure. Basically, Ethernet consists of a shared transmission media, such as twisted pair cable or coaxial cable, and multi-port hubs, bridges or switches. Hubs/switches/bridges connect computers, printers and workstations to each other via cables in a star or bus configuration.

Broadband network is also called "broadband network" or simply "broadband". We know that although the speed of dial-up Internet access has increased from 14.4Kbps to 56Kbps in just a few years, 56Kbps should be the limit of general modems due to the quality of telephone lines. In order to obtain faster Internet access speed, we must find another way, so various broadband access services have emerged in recent years. So, what is broadband? In fact, there is no strict definition. Generally, the upper limit of the current dial-up Internet access speed of 56Kbps is used as the boundary. Access of 56Kbps and below is called "narrowband", and access above 56Kbps is classified as "broadband". Broadband also refers to access technology that can use different channels for multiple transmissions on the same transmission medium, and the transmission speed is above 1.5M bits/second. Compared with traditional Internet access technology, the biggest advantage of broadband access technology is that the access bandwidth is greatly expanded, which is generally 30 times that of ordinary dial-up Internet access. Broadband access has always been what the entire Internet industry and the majority of netizens have been striving for. Currently, the broadband access solutions open to the public include ADSL technology based on current telephone lines, CABLE MODEM technology based on existing cable TV lines, FTTB broadband technology with re-laying optical fibers, broadband satellite technology, and local multi-point distribution system LMDS technology. At this stage, ADSL and CABLE MODEM are the most feasible. They do not require rewiring, and the access equipment and usage costs are relatively low. The broadband access method is similar to Ethernet access. In terms of stability alone, it is much stronger than ADSL, and ADSL is an asymmetric digital subscriber line. Although the access is a public network dynamic IP, it is still subject to the speed limit of the operator's public network export. The "broadband connection" often seen in Windows computers is essentially a virtual connection line. After the Windows operating system is installed, the user needs to manually create the "broadband connection" icon. Difference Ethernet is the most common communication protocol standard used in existing local area networks today. This standard defines the cable types and signal processing methods used in local area networks (LANs). Ethernet transmits information packets at a rate of 10-100Mbps between interconnected devices. Ethernet may work in two modes, half-duplex and full-duplex. Broadband does not have a very strict definition. Generally, it is divided by the current upper limit of dial-up Internet access speed of 56Kbps. Access at 56Kbps and below is called "narrowband", and access above is classified as "broadband". If there must be a definition, it is the bandwidth required for the transmission of various media on the network that people can perceive, so it is also a dynamic and developing concept. For ordinary home users, broadband currently refers to a network infrastructure and services with a transmission rate of more than 1M (1M=1024KB) and non-dial-up access that can achieve 24-hour connection.
