Термины, обозначающие скорость Интернета, крайне It is difficult to understand a person who is far from this topic. For example, the provider offers the Internet service at a speed of 1 Mb / s, and you don’t know if this is a lot or a little. Let's figure out what it is - mbps, and how Internet connection speed is measured in general.
Abbreviation
The literal translation of "mbps" (mbit per second) - мегабит в секунду.It is in these units that the connection speed is most often measured. All providers in their advertisements indicate the speed in megabits per second, so we should deal with these values.
How much is 1 mbps?
First, note that 1 bit is the mostsmall unit to measure the amount of information. Along with the bit, people often use bytes, forgetting that the two concepts are completely different. Sometimes they say "byte", meaning "bit," and vice versa. Therefore it is worth considering this question in more detail.
So, 1 bit is the smallest unit of measure. 8 bits equals one byte, 16 bits equals two bytes, etc. That is, you just need to remember that bytes are always 8 times as large as a bit.
Given that both units are very small, forin most cases they use the prefixes "mega", "kilo" and "giga." What these consoles mean, you should be aware of the school course. But if you forgot, it is worth reminding:
- "Kilo" - multiplication by 1,000. 1 kilobit is equal to 1,000 bits, 1 kilobyte is equal to 1024 bytes.
- "Mega" - multiplication by 1,000,000. 1 megabyte is 1,000 kilobits (or 1,000,000 bits), 1 megabyte is equal to 1024 kilobytes.
- "Giga" - multiplication by 1,000,000,000. 1 gigabit is equal to 1,000 megabytes (or 1,000,000,000 bits), 1 gigabyte is equal to 1024 megabytes.
In simple terms, speedConnection is the speed of the information sent and received by the computer in one unit of time (per second). If your internet connection speed is 1 mbps, what does this mean? In this case, it means that your Internet speed is 1 megabit per second or 1,000 kilobits / second.
How much is this
Many users believe that mbps islot. In fact, it is not. Modern networks are so developed that, given their capabilities, 1 mbps is nothing at all. We give the calculation of such speed on the example of downloading files from the Internet.
We take into account that mbps is megabits per second.We divide the value of 1 by 8 and get megabytes. Total 1/8 = 0.125 megabytes / second. If we want to download music from the Internet, then provided that one track weighs 3 megabytes (usually tracks so much and weigh), we can download it in 24 seconds. It is easy to calculate: 3 mebagyta (weight of one track) should be divided by 0.125 megabytes / second (our speed). The result is 24 seconds.
But this only concerns the usual song. And if you want to download any movie, the size of 1.5 GB? Let's count:
- 1500 (megabytes): 0.125 (megabytes per second) = 12,000 (seconds).
We translate seconds into minutes:
- 12,000: 60 = 200 minutes or 3.33 hours.
Thus, with an Internet speed of 1 mbps, we can download a movie with a capacity of 1.5 GB in 3.33 hours. Here you can judge for yourself whether it is long or not.
Given the fact that in large citiesInternet providers offer Internet speeds up to 100 mbps, we would be able to download a movie with the same volume in just 2 minutes, not 200. That is, 100 times faster. If you start from this, then you can come to the conclusion that mbps is low speed.
Впрочем, все относительно.In some remote village, where it is generally difficult to catch even a GSM network, having the Internet at such a speed is great. However, in a large metropolis with huge competition between providers and mobile operators such a weak Internet connection can not be.
Conclusion
Now you know how to determine the speedInternet, and a little can understand these units. Of course, to get lost in them is to spit, but the main thing to remember is that the bit is the eighth part of a byte. And the prefixes "kilo", "mega" and "gigabyte" only add three, six or nine zeros, respectively. If this is understood, then everything falls into place.
