There is no strict definition of broadband. From a general point of view, it is the bandwidth that can meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept.
On January 7, 2015, the Federal Communications Commission (FCC) made its annual broadband progress report, in which the current chairman, Tomwheeler, redefined "broadband", adjusting the original downlink speed of 4Mbps to 25Mbps, and the original uplink speed of 1Mbps to 3Mbps.
The new standard for broadband networks in the United States: 25Mbps downlink and 3Mbps uplink.
By the end of 2020, China's fixed broadband household penetration rate had reached 96%, and the mobile broadband user penetration rate had reached 108%.

Broadband is a relative way of description, and the larger the frequency range, that is, the higher the bandwidth, the more data can be sent. The FCC explains that any internet connection with a transmission rate of more than 4Mbps can be called broadband.
In fact, there is no very strict definition of broadband. From a general point of view, it is able to meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing general concept.
In basic electronics and electronic communications, it is a description of a continuation number or an electronic circuit that contains or is capable of simultaneously handling a wide range of frequencies. Broadband is a relative way of description, the larger the frequency range, that is, the higher the bandwidth, the more data can be sent. The FCC explains that any internet connection with a transmission rate of more than 4Mbps can be called broadband.
Difference Between Broadband and Ethernet Cable:
Their nature is different, broadband and network cable are two different properties of the object, there is a difference between them in essence, broadband is a kind of rock god destruction concept, indicating a dynamic information transmission rate, and network cable is a medium, is the carrier of information transmission; The role of broadband is to transmit network information at different rates.
The network cable is to make the devices connect with each other and improve the network information transmission efficiency between the devices; There are different ways of existing, broadband exists in a virtual way, there is no physical one. A network cable is an actual cable that has a specific form.

The greater the frequency variation of the signal, the wider the bandwidth of the signal. The formula for the relationship between bandwidth and frequency: bandwidth data line width * transmission line clock frequency * number of times data is transmitted per clock pulse 8.
The signal frequency is also called the frequency signal. This is usually due to the bandwidth of the signal splitting. The frequency component of a signal can be observed from the spectrogram of the signal.
The difference between the highest frequency and the lowest frequency of the harmonics contained in a signal, that is, the frequency range of the signal, is defined as the bandwidth of the signal.
Bandwidth and broadband are different.
1. Broadband is a relative way of description. Bandwidth is a unit.
2. Bandwidth is a measure word, which refers to the size of the network speed. Broadband is a noun that indicates that the transmission rate of the network is very high.
3. Broadband is a relative way of description, including the concept of bandwidth, the larger the frequency range, that is, the higher the bandwidth, the data that can be sent is also relatively increased.
4. Broadband is a description of a signal or electronic circuit that contains or can process a wide range of frequencies at the same time, and bandwidth is one of the indicators that identify the performance of the bus and memory.
5. Broadband is a dynamic concept, and bandwidth is a fixed specific concept.
Error 691 is a fault message that is commonly encountered by broadband ADSL dial-up Internet users. Broadband ADSL dial-up Internet access uses PPPoE protocol connection, transmits data through ** line, and uses ADSL dedicated modem to realize data modem, prompting error 691 in a real sense may be due to the following reasons: 1: >>>More

The subject matter refers to the object to which the rights and obligations of both parties are directed, and is a specific term in the commercial sales contract, that is, the object or commodity referred to in the sales contract. In the concept of law, there is a certain difference between the subject matter and the subject matter. For example, in a housing lease, the subject matter is the housing lease relationship, and the subject matter is the rented house.
