The relationship between broadband and network speed is: "1Mbps=1024Kbps=1024/8KBps=128KB/s", that is, the network speed of "1M" broadband will not exceed "128KB/s"; it is generally considered that bandwidth The larger the network speed, the faster it will be. What is correct is that bandwidth is not directly related to network speed. In actual use, network speed may have a certain impact on the router's transmission rate and other factors due to server problems on the website itself.
The operating environment of this tutorial: Windows 10 system, DELL G3 computer.
What is the relationship between bandwidth and network speed
The relationship between bandwidth and network speed is: 1Mbps=1024Kbps=1024/8KBps=128KB/s.
First of all, the complete unit of the 200M broadband optical fiber mentioned by the operator is 200Mbps, while the download speed unit mentioned in our computers is: MB. Therefore, 200M broadband download speed does not mean that the download speed is 200Mb/s.
That is to say, the download speed of 1M broadband will not exceed 128KB/s, which means that in theory, 128K content can be downloaded in 1 second. In fact, with 1M broadband, the download speed of 100k/s is normal. After all, The theoretical value may not be achieved. The download speed of 200M broadband is theoretically: 128KB/s x 200 = 25600 KB/s = 25.6MB/s.
What is the difference between bandwidth and broadband?
Bandwidth is a quantifier, which refers to the size of the network speed. For example, 1Mbps means one megabit per second, and this value refers to the bandwidth.
Broadband is a noun, indicating that the transmission rate of the network is very high. Broadband standards vary. Initially, bandwidths above 128kbps were considered broadband, while bandwidths below 128kbps were considered narrowband.
But now domestic operators generally provide broadband services with at least 512kbps bandwidth. In other words, bandwidth is a specific value, while broadband is a transmission standard (service) that meets a certain bandwidth value.
That is: broadband is a business, and bandwidth is the transmission speed.
Broadband: In digital communications, it usually refers to the bandwidth of signals above 64kbit/s.
Narrowband: In digital communications, it usually refers to the bandwidth of signals below 64kbit/s.
1. Broadband
Usually people will ask whether your home can access the Internet? In fact, this means whether your home has broadband. In other words, it is a noun. The word broadband comes first, and then you can say what your bandwidth is. Broadband has no direct relationship with the speed of Internet access.
2. Bandwidth
When we want to apply for broadband, we need to register with some service providers. At this time, depending on the package, you may have 10Mb/s, 20Mb/s, etc. You can use the computer byte conversion ratio to calculate your own bandwidth
For example:
1B=8b //1 byte = 8 bits 1KB = 1024B1MB =1024KB1GB=1024MB
The bandwidth we applied for is 10Mb/s. The b in this unit is lowercase, and the 1B (byte) we just mentioned = 8b (bit), which is exactly 8 times the relationship. , that is, the download speed: 10Mb / 8 = 1.25MB
Some people will ask, why should we divide by 8?
In computers, the download speed is measured in bytes (B) units, while the provider says it is in bits (b).
For example: When downloading a software on the Internet, the unit will be B (byte). Another example is that you open a web page. This web page may contain pictures, text, videos, etc. The essence of these contents is Speaking of which, it is downloaded to your computer and then you can see it.
We can calculate our own download speed by bandwidth:
Calculation method: Bandwidth size / 8

600m宽带实际网速为60M-70M左右每秒。600M指的就是600兆(Mpbs)宽带,换算成以字节计算的数据传输速度:1Mbps=1/8MBps,那么600兆宽带的下载速度就是“600÷8=75MB/s”,也就是每秒75MB的下载速度;但这个数据只是理论下载速度,实际上宽带下载速度受很多因素影响,比如说路由器网络传输占道、网络延迟问题,一般实际网速在60M-70M左右每秒。

200mbps是200兆宽带。所谓的宽带200兆其实就是指宽带所接入的速率是200兆;因为“1Mbps = 1024kbps = 1024/8 KBps = 128KB/s”,换算一下,200M宽带的下载速度就是:“200 * 128 KB/s = 25600 KB/s = 25600 / 1024 MB/s = 25.6MB/s”。

区别:以太网是当今现有局域网采用的最通用的通信协议标准,以太网在互联设备之间以10-100Mbps的速率传送信息包;宽带并没有很严格的定义,一般是以56Kbps为分界,将56Kbps及以下的接入称为“窄带”,之上的接入方式则归类于“宽带”。

1000兆宽带下行速率是1000 Mbps,上行速率是30 Mbps;但准确来说,上行速率是不一定的,因为普通用户上行速率都有限速,与办理宽带当地运营商有关;一般如果是专线宽带,则上行速率和下行速率对等。

30mb/s大概是240兆宽带,换算公式是“30MB/Sx8=240M”;通常所说的文件大小的兆是指4MByte;字节(Byte)是计算机信息技术用于计量存储容量的一种计量单位,也表示一些计算机编程语言中的数据类型和语言字符。

校园网和宽带的区别在使用场景和网络范围、速度和带宽、服务提供商、使用限制和服务内容等方面。详细介绍:1、使用场景和网络范围,校园网是针对学校、大学或者教育机构内部提供的局域网服务,它主要覆盖学校的教学楼、宿舍楼等区域,为学生、教职员工提供网络连接服务,通常由学校自行搭建和管理,提供特定的网络资源和服务,宽带是一种广域网服务,提供给个人用户或者家庭使用的高速互联网连接等等。

宽带移机是指客户所装宽带需要迁移变更到新的装机地址时,向电信公司提出移机业务申请,电信公司根据客户要求和资源情况,及时为客户进行宽带业务的地址迁移;户主只需要携带身份证到当地营业厅办理移机业务即可。

在如今这个数字时代,宽带已经成为我们每个人、每个家庭的生活必需品。如果没有它,我们会坐立难安、心绪不宁。那么,你知道宽带背后的技术原理吗?从最早期的56k“猫”拨号,到现在的千兆城市、千兆家庭,我们的宽带技术到底经历了怎样的变革?今天这篇文章,我们就来详细了解一下——“宽带的故事”。█xDSL和ISDN下面这个界面,你见过吗?我相信很多70后80后的小伙伴,肯定见过,并且非常熟悉。没错,这就是当年我们最初接触互联网时,进行“拨号上网”的界面。那还是20多年前,小枣君还在上大学的时候。为了上网,我
