Why is the speed of my 3M cable still slow?

The speed of 3M is 3MB 8 = 375KB S bytes per second.

Popular science: The smallest unit of measurement for a file in a computer is bytes, abbreviated as b (1MB=1024KB, 1KB=1024B.). ）

The smallest unit of data processing in a computer is bits, abbreviated as b (1b=8bit).

The bit is the smallest unit, representing the state of a level, 0 is the low level, 1 is the high level, the computer transmits the data in the state of the level, so it is all binary, a letter needs 8 levels of data to transmit the end: 00101011....

The unit of bandwidth for telecommunications is 1MB, not 1MB, therefore:

Mbps is a unit of Internet speed, 3Mbps is 3 megabits per second;

Internet traffic units are in GB, MB, and KB, 1GB = 1024MB, 1MB = 1024KB, 1KB = 1024B, 1B (bytes) = 8bits (bits). mb to mb, where b and b are converted as: 1b = 8bits;

At present, the downlink rate of China Unicom's wireless network card is Mbps and 21 Mbps (HSPA Mbps, and the highest uplink rate is Mbps).

Normal: You use telecommunications, right? The speed of this speed has a lot to do with the quality of your equipment and the coverage strength of the signal at your location. Generally speaking, if 3Mbps is normal, it will exceed 2M Internet speed and mine, and the speed will be generally 250kb 300kb per second.

This person really doesn't know much.,Did you say that the icon in your taskbar shows 3Mbps there.,This is normal.,Now the notebook wireless network card supports up to 54M,Of course, there are also 11M network cards,And the wireless router now supports up to 300M,There is no 1000M network card at all,1000 is wired,You also have nothing to do with your driver,Besides, no matter how high your network card support, it's useless,Support 54M,Do you have a 54M network? It makes sense that the router supports a high rate, it is convenient for multi-terminal access, your network card should be a relatively new one, the old network card does not have this function, you can display the speed of the connection, this is to show the speed of your connection to the router, not the speed of connecting to the Internet, the speed of connecting to the Internet will be very low, showing 3m proves that your computer and the router are not connected well, the normal connection should be displayed 54m, you double-click your wireless icon to open is not to show only 1 2 grid signal, it is recommended that you adjust the position of the router to achieve the ideal effect, and the display of 54m is normal.

The speed of broadband is calculated in mb s.

On a daily basis, we calculate file size, hard disk storage space, and file copy speed, which are calculated in mb s.

In this way, there is a question of how to convert between mb s and mb s ......

This problem is not simply a matter of capitalization and lowercase of the letters b and b, but a problem involving binary calculations.

Specifically, it is 1byte = 8 bits......

More specifically, 1byte = 8bit, 1KB = 1024byte, 1MB = 1024KB, 1GB = 1024MB, 1TB = 1024GB.

Therefore, the so-called 300m broadband, its specific transmission rate, is about what it looks like.

Such a transfer speed is already very fast.

You know, the actual sustained transfer rate of the hard disk we use is about ...... like thisHDDs may not even be able to reach this speed......

Such speed, of course, is enough.

Of course, if we pursue the extreme, this 300m broadband may not be enough to use ......After all, when it comes to speed, there is no such thing as the fastest, only a faster state......

Bandwidth generally refers to the theoretical speed of **,,1m=1024 8=128kb s,,2m=2*1024 8=256kb s,,3m=3*1024 8=384kb s,,4m=4*1024 8=512kb s,5m=5*1024 8=640kb s,6m=6*1024 8=768kb s,7m=7*1024 8=896kb s,8m=8*1024 8=1024kb s, 9m=9*1024 8=1152kb s,10m=1280kb s，11m=1408kb s，12m=1536kb s，13m=1664kb s，14m=1792kb s，15m=1920kb s，16m=2048kb s，17m=2176kb s，18m=2304kb s，19m=2432，20m=2560kb s。

The units of data transmitted by the network k (thousand), m (megabyte), and g (gigabyte) are not calculated according to the decimal 1000, but according to the binary 1024 to the 10th power; The length of the data is not 10 bits, but binary numbers processed by computer.

According to the minimum length of 8 bits (8 bits, 16 bits, 32 bits of CPU, many are already 64-bit CPUs, but they are multiples of 8, so according to 8 bits), 1KB=1024*8bit (English bit=English abbreviation as B=Chinese bits), 1M=2 to the power of 10 kb = 1024B (B=byte=byte=8B) = 1024*1024*8B, 1G=2 of the 10th power m=1024M=1024*1024kb=1024*1024*1024*8b。

Computer work only recognizes the two numbers 0 and 1, which are equivalent to the light on and off, which is called binary number. If the CPU of a computer with 1 bit (the length of the data bit is 1 bit, that is, the length of the bytes) is calculated once in 1 second, and its binary number 0 is flipped to 1 and changed once, and the two numbers 0 and 1 can be seen by standing outside the CPU for 1 second, that is, 2 1 (2 to the 1st power = 2) numbers, and calculating 10 times in the final clock of 1 second is equal to 2 10 (2 to the 10th power) = 1024, then the CPU of the 8-bit computer needs to calculate 10 times in 1 second, and it needs to exchange 1024 8-bit data with the outside world. It is equivalent to a bandwidth of 1KB, b = byte length of 8 bits, called 8 bits in English, abbreviated as.

BPS is the English abbreviation of bit per second, using mathematical symbols.

The expression is: b s, translated as Chinese is: bits per second, so bps = b s≠b s, kb s can not be expressed as kbps, generally see kbps, kbps as kbps or as kbps.

8bit so you can calculate that 3072 divided by 8 equals 384kbyte, which is the ideal value. And then there's the loss. Typically 300k seconds.

There should be no problem! My internet speed test for 4m was around 470kb!

Mine is for Telecom, and Netcom's internet speed is slower than Telecom's!

It's low, it's miserable. 3m is at least 300k s, and my telecom sometimes goes to 200k s for 1m

First of all, I will introduce you to a few necessary knowledge points::

The smallest unit of measurement for a file in a computer is bytes, abbreviated as b1mb=1024kb 1kb=1024b

m is a trillion, in real life it should be a million, k is a thousand, and in real life it is 1000And the computer is 1024 because it is in 2 base units).

The smallest unit of data processing in a computer is bits, abbreviated as b (1b=8bit).

The bit is the smallest unit, representing the state of a level, 0 is the low level, 1 is the high level, the computer transmits the data in the state of the level, so it is all binary, a letter needs 8 levels of data to transmit the end: 00101011....

The unit of bandwidth for telecommunications is 1MB, not 1MB, therefore:

Therefore, the network speed of 3M is 3MB 8=375KB S bytes per second.

Your speed is obviously 2M, contact the network access provider!

According to you, the speed of the Internet should not be 3M.

The calculation process of the network speed of 3 m s is (384 kb s*8) 1024 = 3 m s In the calculation of network speed, b=bit, b=byte

8 b = 1 b means that 8 lowercase b is an uppercase b, and the definition of the two is different.

And so on

Is your new computer low-spec, or try to make a new system for the computer

What does 3M network cable mean? I don't understand...

3m refers to "rate", which is 3 mbps

His conversion relationship with velocity (kb s) is 8:1

That is, 3Mbps = 3 * 1024 kbps = 384 kb s, due to the transmission interference of the physical link, the actual speed will be about 80% of the theoretical speed, which is 384*, so your network speed is normal.

I'm talking about the ultimate speed, which is the maximum bandwidth capacity that the internet company gives you, regardless of other factors.

And less than 100k There are a lot of reasons I know your specific situation I can't analyze a few common ones.

1. The other party's server is busy.

2. Your physical circuits are aging or poorly contacted.

3. Converter failure (ADSL cat or photoelectric converter)...

…1. The influence of viruses, Trojans, malware and other factors can cause slow network speed.

2. The parameter setting of machines and network equipment will also directly affect the speed of the network. Clever Fight.

3. The quality of hardware equipment such as network cards, network cables, switches, routing, and cables also has a crucial impact on network speed.

4. Internet access, such as peak hours, will also affect the network speed.

6. There is also the problem of bandwidth occupancy, such as opening many network programs at the same time, which will occupy a part of the bandwidth; There is also the sharing of the network, which also has to be divided into a part of the bandwidth.

7. There are many, many, and many, which requires you to pay more attention to it.

In the case of making sure that your method of testing the network speed is correct, this question is that the line is buried in the line, either your home network cable has been used for several years and the line is aging, or there is a joint in the middle of the line, and there is no oxidation before checking the joint.

Too many people surfing the Internet at one time can also affect internet speed.
