This article mainly introduces the difference between Ethernet and broadband, the article is very detailed, has a certain reference value, interested friends must read it!

Difference: Ethernet is the most general communication protocol standard adopted by the existing local area network. Ethernet transmits packets between interconnected devices at the rate of 10-100Mbps; broadband is not strictly defined, generally with 56Kbps as the boundary, access with 56Kbps and below is called "narrowband", and the access mode above is classified as "broadband".

Ethernet connection: the local connection appears only in Microsoft's Windows XP/7 operating system, Windows 8Accord 8.1, and the local connection is renamed "Ethernet". Whether it is a "local connection" or "Ethernet" is actually a reflection of the physical network card (network adapter) on the computer.

Ethernet is the most general communication protocol standard used in the existing local area network, which was established in the early 1970s. Ethernet (Ethernet) is a common local area network (LAN) standard with a transmission rate of 10Mbps. In Ethernet, all computers are connected to a coaxial cable, using carrier-induced multiple access (CSMA/CD) method with collision detection, competition mechanism and bus topology. Basically, Ethernet consists of shared transmission media, such as twisted pair or coaxial cable and multi-port hubs, bridges, or switches. 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 "broadband" for short. We know that although the speed of dial-up Internet access has increased from 14.4Kbps to 56Kbps in just a few years, due to the quality of telephone lines, 56Kbps should be the limit of the general Modem. In order to get faster Internet access, it is necessary to split the stream path, so a variety of broadband access services have emerged in recent years. So, what is broadband? In fact, there is no very strict definition. Generally speaking, the upper limit of the current dial-up rate 56Kbps is taken as the demarcation line, the access of 56Kbps and below is called "narrowband", and the access mode above is classified as "broadband". Broadband also means that multiple transmissions can be carried out with different channels on the same transmission medium, and the transmission speed is 1. Access technology of more than 5m bits per second. Compared with the 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 access.

Broadband access has always been pursued by the entire Internet industry and the majority of netizens. At present, the broadband access schemes that have been opened to the public are ADSL technology based on current telephone lines, CABLE MODEM technology based on existing CATV lines, FTTB broadband technology based on re-laying optical fiber, broadband satellite technology, local multipoint distribution system LMDS technology and so on. At this stage, ADSL and CABLEMODEM are the most feasible, they do not need to rewire, access equipment and use costs are relatively low. Broadband access is already 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 limited by the public network exit speed of the operator.

The "broadband connection" that is often seen in Windows computers is essentially a virtual connection. After the Windows operating system is installed, the user is required to manually create the Broadband connection icon.

The difference between Ethernet and Broadband

Ethernet is the most general communication protocol standard used in the existing local area network. The standard defines the cable types and signal processing methods used in the local area network (LAN). Ethernet transmits packets between interconnected devices at a rate of 10-100Mbps. Ethernet may operate in two modes, half-duplex and full-duplex.

In fact, broadband is not strictly defined. Generally speaking, it is demarcated by the current upper limit of dial-up rate 56Kbps, and the access of 56Kbps and below is called "narrowband", while the access mode above is classified as "broadband". If there must be a definition, it can meet the bandwidth needed for all kinds of media to be transmitted on the network, which can be felt by people's senses, so it is also a dynamic and developing concept. At present, broadband for ordinary home users refers to the network infrastructure and its services with transmission rate of more than 1m (1M=1024KB) and non-dial-up access that can be connected for 24 hours.
