The Difference between Ethernet and Broadband
Ethernet is the most common communication protocol standard used by existing local area networks today and was established in the early 1970s. Ethernet (Ethernet) is a commonly used local area network (LAN) standard with a transmission rate of 10 Mbps. In Ethernet, all computers are connected on a coaxial cable, using a carrier-sensing multiple access (CSMA/CD) method with collision detection, using a contention mechanism and a bus topology. Basically, Ethernet consists of a shared transmission medium, such as twisted pair cable or coaxial cable, and a multiport hub, bridge, or switch. In a star or bus configuration, hubs/switches/bridges connect computers, printers, and workstations to each other through cables.
Broadband network is also called "broadband network" or simply "broadband". We know that in just a few years, the rate of dial-up Internet access has risen from 14.4Kbps to 56Kbps, but limited by the quality of the telephone line, 56Kbps should be the limit of a general Modem. In order to obtain a faster Internet speed, it is bound to have to split the stream, so in recent years, various broadband access services have appeared one after another. So, what is broadband? In fact, there is no strict definition. Generally, the upper limit of the current dial-up Internet speed is 56Kbps as the boundary, and the access of 56Kbps and below is called "narrowband", and the access method above is classified as "broadband". Broadband also refers to an access technology that can use different channels for multiple transmissions on the same transmission medium, and the transmission speed is above 1.5M bits/sec. 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 the pursuit of the entire Internet industry and the majority of netizens. At present, the broadband access solutions that have been opened to the public include ADSL technology based on existing telephone lines, CABLE MODEM technology based on existing cable TV lines, FTTB broadband technology based on re-laying optical fibers, broadband satellite technology, and LMDS technology for local multipoint distribution systems. Wait. At this stage, ADSL and CABLEMODEM are the most feasible, they do not need re-wiring, access equipment and use costs are relatively low. Broadband access is already similar to Ethernet access. In terms of stability, 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 limited by the operator's public network export speed.
The "broadband connection" often seen in Windows computers is essentially a virtual connection line. After the Windows operating system is installed, the user is required to manually create the "Broadband Connection" icon.
The difference
Ethernet is the most common communication protocol standard used in today's existing local area networks. This standard defines the cable types and signal processing methods used in local area networks (LANs). Ethernet transfers packets of information between interconnected devices at rates of 10-100Mbps. Ethernet may work in two modes, half duplex and full duplex.
Broadband does not actually have a very strict definition. Generally, the upper limit of the current dial-up Internet speed is 56Kbps as the boundary, and the access of 56Kbps and below is called "narrowband", and the access method above is classified as "broadband". If there must be a definition, it can satisfy the bandwidth required for transmission of various media that people can feel and feel on the network, so it is also a dynamic and developing concept. For ordinary home users, the current broadband refers to the network infrastructure and its services with a transmission rate exceeding 1M (1M=1024KB) and enabling 24-hour connection without dial-up access.
