Editor to share with you what is the difference between Ethernet and broadband in the computer network, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

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 mode of wired broadband is similar to that of Ethernet access.

The difference between Ethernet and broadband:

1. Ethernet: it refers to the baseband LAN specification created by Xerox and jointly developed by Xerox, Intel and DEC. It is the most general communication protocol standard adopted by the existing LAN. Ethernet networks use CSMA/CD (Carrier sense multiple access and collision Detection) technology and run on many types of cables at 10M/S rates. Ethernet is similar to the IEEE802.3 series of standards.

2. Wired broadband: the access mode of wired broadband is similar to that of 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.

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 by all kinds of media that people can feel on the network, 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.

Many people worry that the bandwidth of Cable Modem is shared, and the speed will slow down as the number of people surfing the Internet increases. Here, we will explain it from different aspects, such as technology and trend, to help you understand the bandwidth of Cable Modem. It has been mentioned earlier that Cable Modem can produce a bandwidth of 27m / 36 Mbps with different modulation techniques in a single cable channel, which is equivalent to the bandwidth of 16-22 ADSL lines. Based on the bandwidth on each Cable channel and the number of users surfing the Internet at the same time on that channel, we can calculate the average bandwidth that each person can feel.

The reason for using "feel" here is that the bandwidth of Cable Modem, like Ethernet0, is shared by all users. The estimation method of bandwidth available to each person on a shared media (Shared Media) is estimated by a mode called "statistical multiplex". When other users do not carry out a large number of transmissions, users can enjoy almost all the bandwidth alone. This is why cable modem users can often enjoy ultra-high speed. It is estimated that each broadband user can enjoy an average speed of 200,500 Kbps. The fastest transmission speed is 1500 Kbps (equivalent to an ADSL dedicated line). With the development of the network in the future, when the transmission speed is above 1Gbps, the average speed that each user can enjoy will be above 2Mpbs.

The above is all the contents of the article "what is the difference between Ethernet and Broadband in computer Network". Thank you for reading!
