Xiaobian to share with you how much broadband speed in the computer network is appropriate, 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 broadband rate is about [103--200kB/s], which is caused by many factors, such as user computer performance, network equipment quality, resource usage, network peak period, website service capacity, line attenuation, signal attenuation and so on.

Broadband rate refers to the maximum theoretical rate that can be achieved technically, generally the speed of uploading and downloading. The higher the rate, the faster the uploading and downloading. The broadband service rate applied by users is the maximum theoretical rate, because users are also affected by the configuration of computer software and hardware, the address of the website they browse, and the bandwidth of the opposite website when they surf the Internet, therefore, the rate of users surfing the Internet is usually lower than the theoretical rate.

Theoretically, 2m, that is, 2Mb/s, the theoretical rate of broadband is 256KB/s. The actual rate is about 103--200kB/s. The reason is due to the influence of many factors, such as user computer performance, network equipment quality, resource usage, network peak period, website service capacity, line attenuation, signal attenuation and so on. 4m, that is, the theoretical rate of 4Mb/s broadband is the actual rate of 512KB/s is about 200---440kB/s.

Because ADSL uses two different frequency bands to transmit uplink and uplink channels respectively, its downlink can reach 8Mbit/s and uplink can reach 640Kbit/s. Operators can provide individual users with a download rate of 512Kbit/s, and it can also dynamically adjust the access speed of users according to the quality of the telephone line and the transmission distance, which can fully meet the requirements of multimedia video applications.

In computer science, the bit is the smallest unit of information, called the binary bit; it is generally denoted by 0 and 1. A Byte is called a byte and consists of eight bits (8bit) to form a byte (1Byte), which is used to represent a character in a computer. The conversion between bit and Byte can be carried out, and the conversion relationship is: 1Byte=8bit (or abbreviated as: 1B=8b); in practical application, it is generally used as abbreviation, that is, 1bit is abbreviated to 1b (note that it is the lowercase letter b) and 1Byte is abbreviated to 1B (note that it is the capital letter B).

In computer networks or network operators, generally speaking, the unit of broadband rate is expressed as bps (or bhand s); bps represents the number of bits per second, which is the abbreviation of bit per second. In practice, 1m bandwidth means 1Mbps (megabits per second Mbps, not megabytes per second MBps).

Conversion formula: 1B=8b 1B/s=8b/s (or 1Bps=8bps)

Specification hint: in the actual writing specification, B should represent Byte (bytes) and b should represent bit (bits), but in the actual writing at ordinary times, some people mix bit and Byte as b, such as Mb/s and MB/s as Mb/s, which leads to errors due to the confusion of units in actual calculation.

Example: in our actual Internet applications, when downloading software, we often see the words such as download speed displayed as 128KBps (KB/s), 103KB/s and other broadband speed, because the line bandwidth provided by ISP is in bits, while generally downloading software displays bytes (1 byte = 8 bits), so the actual value can only be obtained through conversion. However, we can convert it according to the conversion formula: 128KB/s=128 × 8 (Kb/s) = 1024Kb/s=1Mb/s, that is, 128KB pick sprints 1Mbps1024Kbps1024Kbps1024bot 8KBps128KBAccords.

The above is all the content of this article "how much is the broadband rate in the computer network?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
