Question 2: What does 100M Internet speed mean? You said it yourself. It's just the speed of the computer to the m伐dem, and the speed to the extranet depends on the operator ah
"100M=1m network speed under something more than 100K, 200M=2M network speed under something more than 200K" That's a blind guess
And, there can't be a 200m Now there are only 10 100 1000 10000
Question 3: What is the concept of 10M speed? Does it mean that the download speed is 10m per second? 10 Mbps of the following telecommunications broadband, the theoretical (lossless maximum) download speed = 10,240 Kb / s = 1280 KB / s = 1.25MB / s
The following is the method of calculation:
The above 10 Mbps complete English meaning is 10 million bits per second; the complete Chinese meaning is 10 megabits per second (also known as 10 megabits / s). can also be called 10 megabits per second).
The "b" in the description of 10 Mbps should be bits, which means bits in Chinese;
and the actual download speed of 2Mbps (for Wuxi) China Telecom's fixed line broadband is 256KB/s,
or 4Mbps for the above broadband is 512KB/s.
The actual download speed of 10 Mbps is 10 million bits per second; in Chinese, it is 10 megabytes per second (also known as 10 megabits per second). Download speed of 512KB / s in the "B" of the full name should be Byte, the Chinese meaning of the byte;
bit (bit) and Byte (byte) can be converted,
the conversion relationship is: 1Byte = 8bit (or abbreviated as: 1B = 8b);
Another: 1Mb = 1024 Kb; 1MB = 1024KB (used in the following conversion);
Simply put, 10 Mbps of the above telecom broadband, 10 Mb converted to Kb, 10 Mb = 10 X 1024 =10240 Kb;
That is, 10 Mbps of the above broadband, the theoretical (lossless maximum) download speed =10240 Kb/sec
To convert 10240 Kb to KB, divide 10240 Kb by 8 = 1280 KB;
i.e., for the above broadband with 10 Mbps, the theoretical (highest lossless) download speed can be expressed as 1280 KB/sec (i.e., 1.25MB/sec).

Note: the above 1bit is a 1-bit binary number, 1Byte is a byte, a byte is composed of 8 binary bits.
The actual network transmission, there are some loss (the same area of different network line interconnection problems, the Yangtze River North and South line different problems) and other aspects of the complexity of the impact of the speed of the actual download speed (specific circumstances due to the environment, equipment, materials vary).
Question 4: 10M bandwidth describes the speed of Internet access, what does 10M mean? Generally speaking, the bandwidth is expressed in bit (bits), and telecom, Unicom, mobile and other operators in the promotion of this unit is often ignored.
The normal conversion is as follows:
1Mbit=128KB
2Mbit=256KB
(and so on)
And the converted speed is your real Internet speed, that is to say, if you open the bandwidth from your carrier is 10M, then substitute into the formula, to the conversion of the above 1M to measure is:
(1M = 1024K)
1M/128K = 1024/128 = 8
10/8 = 1.25M
That is to say, if you open the 10M bandwidth, you can achieve the highest speed of 1.25M Generally speaking, a computer to watch movies, play games, etc., 4M bandwidth is enough.
The "maximum data rate" that can be passed from one point in the network to another in a unit of time. A better analogy for the concept of bandwidth is the highway. The amount of data that can be transmitted on the line in a unit of time, commonly used unit is bps (bit per second). The bandwidth of a computer network is the maximum rate of data that can pass through the network, i.e., how many bits per second.
Question 5: What does the "M" for "Mbps" mean? The M in "Mbps" for "Mbps" usually refers to Mbps. Mbps = Mbit/s or megabits per second (abbreviation for "Million bits per second"). bps (bits per second), that is, the bit rate, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second, bits per second. / second, bits / second, bits per second, the number of bits transmitted per second, the common unit of data transmission rate.
The file size is usually referred to as 8MByte. byte is a unit of measurement used in computer information technology to measure storage capacity, and also represents the data types and language characters in some computer programming languages.
The conversion relationship between bytes and bits is as follows:
1Byte = 8bit
1KByte = 1024Byte
1M = 1024KByte
Problem 6: The concept of network speed The broadband speed mentioned in the product introduction of the carrier refers to the physical speed between the Modem on the user's end and the telecom's broadband access equipment (DSLAM). (DSLAM) between the physical interface rate. And by the technical characteristics of ADSL determines the upstream and downstream rate is different. The unit of accessing data in computer is "byte", i.e. byte (upper case B), while data communication is made in "word bit", i.e. bit (lower case B), and the relationship between the two is 1byte=8bit. 1M, 2M, 3M, 4M, etc. is calculated by the unit of data communication word bit. Therefore, when the download speed displayed by the computer software is 200KB, the actual line connection rate is not less than 1.6Mbit (1600Kbit). The Internet's network bandwidth is dynamically changing, and its real-time use of bandwidth depends mainly on the following: 1, the operator's backbone export bandwidth; 2, the operator to provide access to the customer's access bandwidth; 3, the customer's access to the content provider's bandwidth; 4, the line and the equipment attenuation; 5, the number of people online at the same time; 6, the user's self-built local area network.
Question 7: What is the relationship between bandwidth and Internet speed? The relationship between bandwidth and Internet speed is that the speed of the Internet is 125KB/sec for 1Mbps broadband, and the relationship between them is the rate, and the theoretical value of 10Mb for the 360 speed test is 10MB/8 ≈ 1.25MB theoretical value, which is of course up and down depending on the user's situation and the load of the network.
Question 8: What is the difference between bandwidth and Internet speed? Hello ~
Broadband and Internet speed are two concepts, you need to know what the broadband refers to, and Internet speed is the concept of knowing the relationship between the two and the difference.
"Broadband" does not have a very strict definition. From a general point of view, it is to be able to meet the people's perception of the various media can be felt on the network transmission of the bandwidth needed, so it is also a dynamic, development concept. FCC (Federal munications mission full name of the U.S. Federal Communications Commission) on July 24, 2010 for the "broadband" this word hacked a definition, the FCC believes that broadband means that the download rate of 4Mbps, up to 1Mbps, can realize the video and other multimedia applications, while maintaining the underlying multimedia applications, while maintaining basic Web browsing and E-Mail features. Current broadband for home users means a transmission rate of more than 1M, which allows for the delivery of large amounts of information such as voice and images.
"Internet speed" Internet speed generally refers to the speed of uploads and downloads when a computer or cell phone is surfing the Internet. To increase the (computer) Internet speed, it depends on the ISP, such as increasing the bandwidth and network flow, and some software, which can also increase the dial-up speed.
The relationship between broadband and Internet speeds is roughly 8 times that of a 2Mbps download speed of about 200KB, which is a different concept.
The so-called 1.5Mbps broadband, in fact, refers to 1.5Mbps (bits per second), that is, 1.5 x 1024 / 8 = 192KB/sec, but this is just the theoretical speed, and in practice, about 12% is deducted. However, this is only a theoretical speed, and in reality, about 12% of the Ethernet Header, IP Header, TCP Header, ATM Header and other control signals have to be deducted, so the upper limit of the transmission speed should be about 169KB/sec. In terms of transmission units, B and b stand for Bytes and bits, respectively, which are defined differently, so don't get confused.
I hope to help you ~
Question 9: What is the meaning of the usual "Internet speed is 4 megabytes or 10 megabytes" Originally, megabytes (M) is a unit of capacity, such as the size of the computer file, 1MB (megabytes) = 1024KB (kilobytes) = 1024 × 1024B (bytes). And network bandwidth using M is shown in a time period (usually seconds) through the communication line a cross-section of the maximum amount of information transmitted, so we use megabytes (M) to indicate the amount of information, so the unit of bandwidth is megabytes (M).
In general, the theoretical download speed of 1 megabyte is 1024 / 8 = 128KB, so the so-called 4 megabytes of 10 megabytes is multiplied by 128KB after the speed.
