What is the difference between Ethernet and Broadband

The difference between Ethernet and broadband: 1. Ethernet refers to the baseband LAN specification created by Xerox and jointly developed by Xerox, Intel and DEC; 2. The access method of wired broadband is already similar to Ethernet is connected.

The difference between Ethernet and broadband:

1. Ethernet: refers to the baseband LAN created by Xerox and jointly developed by Xerox, Intel and DEC Specification is the most common communication protocol standard used in existing local area networks today. Ethernet uses CSMA/CD (Carrier Sense Multiple Access and Collision Detection) technology and runs on multiple types of cables at a rate of 10M/S. Ethernet is similar to the IEEE802.3 series of standards.

2. Wired broadband: The access method of wired broadband is similar to Ethernet access. In terms of stability, it is much stronger than ADSL, which 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.

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 carries packets of information between interconnected devices at a rate of 10-100Mbps. Ethernet may operate in two modes, half-duplex and full-duplex.

Broadband is actually not strictly defined. Generally, the current upper limit of dial-up Internet speed is 56Kbps as the demarcation. Access methods of 56Kbps and below are called "narrowband", and access methods above are classified as "narrowband". Similar to "broadband". If there must be a definition, it is the bandwidth required for the transmission of various media on the network that can be felt by people's senses. Therefore, it is also a dynamic and developing concept. For ordinary home users, current broadband refers to non-dial-up access network infrastructure and services with a transmission rate exceeding 1M (1M=1024KB) and enabling 24-hour connection.

Cable broadband speed

Many people are worried that the bandwidth of Cable Modem is shared, in case the number of people accessing the Internet If it is too high, the speed will decrease. Here we explain it from different perspectives, including technology and trends, to help you understand how large the bandwidth of Cable Modem is. As mentioned before, Cable Modem can produce a bandwidth of 27 M/36 Mbps on a single cable TV channel using different modulation techniques, which is equivalent to the bandwidth of 16-22 ADSL dedicated lines. Based on the bandwidth on each Cable channel and the number of users surfing the Internet on this channel at the same time, we can calculate the average bandwidth that each person can feel.

The reason why "feeling" is used here is because the bandwidth of Cable Modem is the same as Ethernet0 and is shared by all users. The estimation method of the bandwidth available to each person on a shared media (Shared Media) is estimated using a model called "statistical multiplexing". When other users do not make large transmissions, users Almost all the bandwidth can be enjoyed exclusively, which is why cable modem users can often enjoy ultra-high speeds. It is estimated that each broadband Internet user can enjoy an average speed of 200-500 Kbps, with the fastest being 1500 Kbps (equivalent to The transmission speed of an ADSL dedicated line). In the future network development, when the transmission speed reaches more than 1Gbps, the average speed that each user can enjoy will be more than 2Mpbs.
