What is the difference between server broadband and home broadband?

Generally, the server bandwidth is selected as fiber-to-the-home, and the exclusive bandwidth is directly connected to the server room and motor room, and then allocated by the enterprise's own switches.

The advantage is exclusive bandwidth and a simple and stable network environment.

The disadvantage is that it is more expensive because of the higher cost of laying optical fiber links, equipment costs, and construction costs.

Home broadband: just a noun, usually adslmodem or cable

Modem access, bandwidth usually varies from 1m to 10m (varies by region). If the broadband service provider has more users and smaller egresses, there will be competition for bandwidth between users at night when the traffic peaks.

In addition, the server bandwidth is generally symmetrical in the uplink and downlink, that is, the same broadband as the uplink and downlink loans, and the home broadband is even if it is 100m broadband, it is only downlink (** thing) is 100m, when you want to send files outside, the uplink bandwidth is used, and the uplink bandwidth of the general home is very slow.

Differences:

1.Although the router of the home network has the function of a built-in switch, that is, it has multiple LAN interfaces, but the number of home users connected to the network is not large, so there is no need for a switch to form an intranet.

However, the number of corporate users who need to connect to the network is relatively large, so switches are needed to form an intranet.

2.Home networks are generally connected to the Internet with ** cables.

However, enterprise networks are generally connected to the Internet with optical cables, so general enterprise networks do not need modems.

Background

Small and medium-sized enterprises are an important part of social and economic life, and small and medium-sized enterprises in China (excluding individual industrial and commercial households.

There are more than 11 million enterprises, accounting for more than 95% of the total number of enterprises in China, contributing 55% to GDP and providing 75% of employment opportunities, occupying a very important position in the national economy.

Small and medium-sized enterprises have the following characteristics: strong vitality, very active economic activities, large number, wide range of industries and regions, rapid growth, rapid change, and business model.

Flexibility and other characteristics, while the scale of the enterprise.

It is relatively small and still in a weak position in terms of access to social resources.

The state attaches great importance to the development of small and medium-sized enterprises, and has issued a series of regulations and documents such as the Notice on Promoting the Informatization of Small and Medium-sized Enterprises (2001) and the Law of the People's Republic of China on the Promotion of Small and Medium-sized Enterprises (2002).

clearly stated:

Develop inter-enterprise e-commerce, promote third-party e-commerce transactions and services for small and medium-sized enterprises, key industries and regions", actively support, strengthen guidance, and give policy preferences to small and medium-sized enterprises, creating favorable conditions for the development of small and medium-sized enterprises.

First, the subject is different.

1. Bandwidth: the amount of data that can be transmitted at a fixed time, that is, the ability to transmit data in the transmission pipeline.

2. Broadband: In basic electronics and electronic communications, it describes a signal or electronic circuit that contains or can handle a wide range of frequencies at the same time.

Second, the characteristics are different.

1. Bandwidth: The frequency range occupied by various different frequency components contained in the signal. Bandwidth is especially important for basic output-to-system (BIOS) devices, such as fast disk drives, which are hindered by low-bandwidth buses.

2. Broadband: It is a relative way of description, the larger the frequency range, that is, the higher the bandwidth, the data that can be sent is also relatively increased. For example, in radio communications, the bandwidth with a relatively narrow frequency range can only send Morse code, and the transmission of high-quality ** requires a large bandwidth.

Third, the advantages are different.

1. Bandwidth: It is widely borrowed in digital communication to describe the highest rate at which a network or line theoretically transmits data.

2. Broadband: Broadband represents the ability to receive a large number of channels. In terms of data transmission, the first line is also used as the medium of signal transmission.

What is the difference between broadband and network cable.

Broadband refers to the connection methods that currently provide Internet operation services to everyone. Compared with the PSTN DDN and other Internet access methods (narrowband) with low speed such as PSTN and DDN many years ago, it is called broadband.

Bandwidth refers to the actual rate at which you surf the Internet.

Bandwidth and broadband are two different concepts.

In basic electronics and electronic communications, broadband describes a continuation or electronic line that contains or is capable of handling a wide range of frequencies at the same time. 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.

In computer systems, bandwidth is used as one of the indicators to identify bus and memory performance.

Bus bandwidth refers to the total amount of data that a bus can transmit per unit of time, equal to the product of the bus bit width and the operating frequency.

Memory bandwidth refers to the data transfer capacity that a memory bus can provide. For example, if the data transmission frequency of DDR400 memory is 400MHz, then a single module has a bandwidth of 64bit 400MHz 8(byte)=.

It is the difference between the diameter of the water pipe and the water pipe.

Do you want to ask how to determine which broadband is used?

Just look at the DNS.

Method: There is a "Support" option in the properties of the local connection. There is another "Details" in it, and you can see what the DNS is.

Telecommunications is: or Henan).

Netcom is: or Henan's).

My personal understanding is that bandwidth is a unit in the category of communication. Broadband is a vague term used by our homes, workplaces, etc. to communicate online. I say this, see if you can understand it?

No matter which brand (such as Netcom, Telecom, etc.) has different bandwidths.

The signal frequency is also called the frequency signal. This is usually due to the bandwidth of the signal.

The signal bandwidth is the width of the signal spectrum, that is, the difference between the highest frequency component and the lowest frequency component of the signal, for example, a square wave signal composed of several sine waves superimposed, the lowest frequency component is its fundamental frequency, assumed to be f

2kHz, its highest frequency component is its 7th harmonic frequency, i.e., 7f = 7 2 = 14kHz, so this signal bandwidth is 7f - f = 14-2 = 12kHz. The channel bandwidth limits the lower and upper frequencies of the signal that are allowed to pass through the channel, that is, a frequency passband. For example, if a channel allows a passband of up to 15kHz and its bandwidth is 15kHz, all the frequency components of the above square wave signal can of course pass through the channel, and if the attenuation, delay and noise are not considered, the signal passing through this channel will not be distorted.

However, if a square wave with a fundamental frequency of 1 kHz is passed, the distortion through that channel will certainly be severe; If the fundamental frequency of the square wave signal is 2khz, but the highest harmonic frequency is 18khz, the bandwidth exceeds the channel bandwidth, and the higher harmonics will be filtered out by the channel, and the square wave received through the channel is not sent; So, if the fundamental frequency of the square wave signal is 500Hz, the highest frequency component is the frequency of the 11th harmonic, and its bandwidth only needs to be 5kHz, which is much smaller than the channel bandwidth, can it pass through the channel well? In fact, when the signal is transmitted on the channel, the fundamental frequency is filtered out, and only the harmonics can pass through, and the signal waveform must be unsightly.

bandwidth" to indicate the data transfer rate of the channel.

Therefore, there is a clear relationship between the maximum transmission rate of the communication channel and the bandwidth of the channel, so people can replace the "rate" with "bandwidth". For example, the "high data rate" of a network is often described as the "high bandwidth" of a network. As a result, "bandwidth" and "speed" are almost synonymous in the discussion of network technology.

Differences: 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.
