Guys, hello to all. In short, I had such a joke, just a plague. In general, I now want to write about such as mbps, but I don’t know what it is for garlic. But I looked on the Internet and there I saw Mbps, damn it, and you know what's funny? Just when I saw Mbps with a capital letter, my memory immediately remembered what mbps means! You see, one small detail is enough to remember something.

In general, guys, such as Mbps, you can meet anywhere at all. This is such a term of general use, if I may say so. So wait, what is this? The word Mbps means megabit per second. This is a characteristic of the Internet, although no, not even the Internet, but simply the bandwidth of the channel. Channel, that is, standard, that's how it will even be more accurate. After all, there is a wired and wireless communication standard, but everywhere the data transfer rate is measured in Mbps. By the way, in Russian it sounds like Mbps

That is, we have already understood, yes, what is Mbps? This value measures the data transfer rate!

But how to understand by the Mbps parameter whether the Internet is fast or slow? To understand this, you need to know two things, how much the music, the film, and, well, the very speed of the Internet weigh approximately. But the joke is that music or a movie, they go in megabytes, and the Internet goes in megabits. How to be?

Don't worry, it's simple. For example, let's imagine the Internet at a speed of 100 Mbps and now we will analyze a lot or a little. So how much is the movie? The film in more or less good quality weighs 1500 megabytes. One song in mp3 format and in normal quality weighs about 10 megabytes. But 100 Mbps is how many megabytes? You just need to divide 100 by 8 and we will get how many megabytes are transferred per second. It turns out 12.5, that is, that's how many megabytes are transferred per second. That is, we can say that it is still the Internet is fast. I am now using the Internet at 10 Mbps and it is more than enough for me, although of course I don’t download enough ..

There is a very popular test on the Internet to measure the speed of the Internet, it is called a speed test. So, users there measure speeds and then muddy up such pictures and sometimes brag about them:

I think that now if you see such a picture, then you will understand everything. By the way, you see, there is such a thing as Download, this is the download speed, Upload is the upload speed.

And you know what else? There is also Gbps, what else do you think it is .. It's just not a megabit, but a gigabit! That's 1000 megabits per second!! Or 125 megabytes per second… The speed is just space, but does an ordinary user really need it? Somehow I doubt it...

It is best to check the speed of the Internet for a speedtest. And here is the network connection window:

Here you should not take the value of speed to heart. For here the speed of the local network or another speed is often written, but not the actual speed of the Internet

Look, 1 gigabit speed is generally written here:

But the Internet certainly does not work at that speed. In general, the tariff plan for ordinary users per gigabit is, firstly, a rarity, and secondly, it is terribly expensive. And who needs gigabit, this is already super-speed, as for me ..

I forgot to say something else, here is a simple network card:

Not all of them support gigabit speed, you need to check this in the specifications. This is especially true for PCI network cards. Modern setevukh already support gigibat. Well, the built-in network cards in modern motherboards support gigabit in 99%

But as for Wi-Fi, I don’t even know about it .. I doubt that regular Wi-Fi supports gigabit, I doubt it very much. But I’ve looked at the Internet and yes, there are already gigabit models, but such a speed is possible under ideal conditions: line of sight, no interference, interference ..

Guys, I found a picture, someone was lucky with such high-speed Internet:

That's all, I hope everything I wrote here was a little interesting for you. Good luck and all the best to you

In order to take into account all the nuances when choosing an Internet tariff, you need to know a few facts about the principles of the network that will help you use the services more efficiently.

Megabits and megabytes are two different things. 1 Mbps is about 8 times larger than 1 Mbps. It turns out that having an Internet speed of 8 Mbps, we get a real speed of about 1 Mbps. A 5 MB music track will download (or fully download) in 5 seconds. Thus, knowing your needs in the network, you can calculate the time for which this or that task will be completed at the current tariff.

The final speed of the Internet is determined not only by your provider. Its performance is influenced by the most important factors, for example, network equipment, the speed of the remote server, the level of the wireless signal, the speed of the end device, and so on. If your provider proudly claims 50 megabits per second, then when watching a movie online, you may simply not get such a speed, because that computer with the movie is somewhere far away. The server is busy distributing this film to several thousand or even tens of thousands of the same users.

This is comparable to a wide pipe through which a small stream flows: the source (server) is no longer able to give, and all the extra space is empty. A similar situation occurs if you are with a tablet through 2 walls and a layer of furniture from the router - the speed of the Wi-Fi channel will drop, and no matter how fast Internet comes to your house, it will reach the device at other, lower speeds.

An important indicator of the quality of communication is ping. In essence, ping is the speed of access to data on the Internet, i.e. How fast is the request. If the ping is high at high speed, then there will be practically no sense from it: requests will be slow. A large ping has a particularly negative effect on ordinary web surfing, where each mouse click is sending a request, as well as on online games, where real-time synchronism depends on ping.

One of the most frequent and demanding user tasks - online video. If everything is not so important with music, because the size of the compositions is small, then with the video you should always pay attention to the quality in which you watch it. The higher the quality, the slower the buffering (loading) of the movie or clip. For example, 480p quality requires almost half the speed of 1080, although many reputable sites automatically set video quality, so the problem is not so significant.

Torrents are the surest test of speed. Here, users' computers act as a server, and the speed of sending information to your computer is summed up over all servers. As a result, the overall upload speed can be very high, capable of loading any Internet channel.

Considering all these factors, the following recommendations can be made.

• about 5 Mbps will be more than enough for web surfing and listening to music at the same time, and the Internet channel can be shared by several devices with such tasks
• 10 Mbps can ensure uninterrupted playback of FullHD video on 2 devices, and on the third one you can browse pages quite comfortably
• 20 Mbps is already a serious speed that will allow you to watch a FullHD movie with simultaneous torrent download, and you can still safely hang a phone with a tablet on the channel and comfortably watch Youtube. For correspondence and web surfing, the speed is excessive.
• 40 Mbit. Older routers just don't support these speeds anymore. Needless to say, 40 Mbps is enough for everything. It can only be recommended to users with special tasks, such as an FTP server or working with files in cloud systems. You should not take such a speed if you are just listening to music, chatting on the Internet and sometimes watching movies. It will be an overpayment.
• 60 Mbps and above. Yes, at present, some providers offer such numbers, and they are really rarely needed. It happens that the provider promises even 100 Mbps and higher at night, but to support this speed you need expensive powerful routers and "gigabit" cables. Almost all mobile devices will not be able to open at this speed, and the computer needs either an expensive motherboard with a 1000mb network card, or a gigabit network card.

Taking into account the average requirements of Internet users, in modern conditions, an Internet speed of 15-20 Mbps is enough for almost all tasks. Most often, large numbers mislead users, as if promising that "everything will be fast." But providers are well aware that only a quarter of the same 60 Mbps will be used, so in fact you are supplied with 15-20 Mbps at the price of 60. Most often, the difference is felt only when working with torrent clients, but for most users this is hardly worth the overpayment.

General information

The data can be either digital or analog. Data transmission can also take place in one of these two formats. If both the data and the method of their transmission are analog, then the data transmission is analog. If either the data or the transmission method is digital, then the data transmission is called digital. In this article, we will talk specifically about digital data transmission. Nowadays, digital data transmission is increasingly used and stored in digital format, as this allows speeding up the transmission process and increasing the security of information exchange. Apart from the weight of the devices needed to send and process the data, the digital data itself is weightless. Replacing analog data with digital data helps facilitate the exchange of information. Data in digital format is more convenient to take with you on the road, because compared to data in analog format, for example on paper, digital data does not take up space in luggage, except for the carrier. Digital data allows users with access to the Internet to work in a virtual space from anywhere in the world where the Internet is available. Multiple users can work with digital data at the same time by accessing the computer on which it is stored and using the remote administration programs described below. Various Internet applications such as Google Docs, Wikipedia, forums, blogs, and others also allow users to collaborate on a single document. That is why the transmission of data in digital format is so widely used. Recently, eco-friendly and green offices have become popular, where they are trying to switch to paperless technology in order to reduce the carbon footprint of the company. This made the digital format even more popular. The statement that by getting rid of paper, we will significantly reduce energy costs is not entirely correct. In many cases, this sentiment is inspired by the advertising companies of those who benefit from more people moving to paperless technology, such as computer and software manufacturers. It also benefits those who provide services in this area, such as cloud computing. In fact, these costs are almost equal, since running computers, servers, and supporting the network requires a large amount of energy, which is often obtained from non-renewable sources, such as burning fossil fuels. Many hope that paperless technology will indeed be more cost effective in the future. In everyday life, people also began to work more often with digital data, for example, preferring e-books and tablets to paper ones. Large companies often announce in press releases that they are going paperless to show that they care about the environment. As described above, sometimes this is just a publicity stunt, but despite this, more and more companies are paying attention to digital information.

In many cases, the sending and receiving of data in digital format is automated, and the bare minimum is required from users for such data exchange. Sometimes they just need to press a button in the program they created the data in, such as when sending an email. This is very convenient for users, since most of the data transfer work takes place behind the scenes, in data centers. This work includes not only the direct processing of data, but also the creation of infrastructures for their rapid transmission. For example, in order to provide fast communication over the Internet, an extensive system of cables is laid along the ocean floor. The number of these cables is gradually increasing. Such deep-sea cables cross the bottom of each ocean several times and are laid through the seas and straits in order to connect countries with access to the sea. Laying and maintaining these cables is just one example of working behind the scenes. In addition, such work includes providing and maintaining communications in data centers and ISPs, maintaining servers by hosting companies, and ensuring the smooth operation of websites by administrators, especially those that allow users to transfer data in large volumes, for example forwarding mail, downloading files, publishing materials, and other services.

To transmit data in digital format, the following conditions are necessary: ​​the data must be correctly encoded, that is, in the correct format; you need a communication channel, a transmitter and a receiver, and, finally, protocols for data transmission.

Encoding and sampling

The available data is encoded so that the receiving party can read and process it. Encoding or converting data from analog to digital format is called sampling. Most often, data is encoded in the binary system, that is, information is presented as a series of alternating ones and zeros. After the data is encoded in binary, it is transmitted as electromagnetic signals.

If data in analog format needs to be transmitted over a digital channel, they are sampled. So, for example, analog telephone signals from a telephone line are encoded into digital ones in order to transmit them over the Internet to a recipient. In the discretization process, the Kotelnikov theorem is used, which in English is called the Nyquist-Shannon theorem, or simply the discretization theorem. According to this theorem, a signal can be converted from analog to digital without loss of quality if its maximum frequency does not exceed half the sampling frequency. Here, the sample rate is the frequency at which the analog signal is “sampled”, that is, its characteristics are determined at the time of the sample.

Signal encoding can be either secure or open access. If the signal is protected and it is intercepted by persons to whom it was not intended, then they will not be able to decode it. In this case, strong encryption is used.

Communication channel, transmitter and receiver

The communication channel provides a medium for transmitting information, and transmitters and receivers are directly involved in transmitting and receiving a signal. The transmitter consists of a device that encodes information, such as a modem, and a device that transmits data in the form of electromagnetic waves. This can be, for example, the simplest device in the form of an incandescent lamp that transmits messages using Morse code, and a laser, and an LED. To recognize these signals, you need a receiving device. Examples of receiving devices are photodiodes, photoresistors, and photomultipliers that detect light signals, or radio receivers that receive radio waves. Some of these devices only work with analog data.

Communication protocols

Data transfer protocols are like a language in that they communicate between devices during data transfer. They also recognize errors that occur during this transfer and help resolve them. An example of a widely used protocol is the Transmission Control Protocol, or TCP (from the English Transmission Control Protocol).

Application

Digital transmission is important because without it it would be impossible to use computers. Below are some interesting examples of the use of digital data transmission.

IP telephony

IP telephony, also known as voice over IP (VoIP) telephony, has recently gained popularity as an alternative form of telephone communication. The signal is transmitted over a digital channel, using the Internet instead of a telephone line, which allows you to transmit not only sound, but also other data, such as video. Examples of the largest providers of such services are Skype (Skype) and Google Talk. Recently, the LINE program created in Japan has been very popular. Most providers provide audio and video calling services between computers and smartphones connected to the Internet for free. Additional services, such as calls from a computer to a phone, are provided for an additional fee.

Working with a thin client

Digital data transfer helps companies not only simplify the storage and processing of data, but also work with computers within the organization. Sometimes companies use part of the computers for simple calculations or operations, such as Internet access, and the use of ordinary computers in this situation is not always advisable, since computer memory, power, and other parameters are not fully utilized. One solution to this situation is to connect such computers to a server that stores the data and runs the programs that these computers need to work. In this case, computers with simplified functionality are called thin clients. They should only be used for simple tasks, such as accessing a library catalog, or using simple programs such as cash register programs that write sales information to a database and also issue checks. Typically, a thin client user works with a monitor and keyboard. The information is not processed on the thin client, but sent to the server. The convenience of a thin client is that it gives the user remote access to the server through a monitor and keyboard, and does not require a powerful microprocessor, hard drive, or other hardware.

In some cases, special equipment is used, but often a tablet computer or a monitor and keyboard from a regular computer is enough. The only information processed by the thin client itself is the system interface; all other data is processed by the server. It is interesting to note that sometimes ordinary computers, on which, unlike a thin client, process data, are called thick clients.

Using thin clients is not only convenient, but also profitable. Installing a new thin client doesn't cost much as it doesn't require expensive software and hardware such as memory, hard drive, processor, software, and others. In addition, hard drives and processors stop working in very dusty, hot or cold rooms, as well as high humidity and other adverse conditions. When working with thin clients, favorable conditions are needed only in the server room, since thin clients do not have processors and hard drives, and monitors and input devices work fine in more difficult conditions.

The disadvantage of thin clients is that they do not work well if you need to frequently update the graphical interface, for example, for video and games. It is also problematic that if the server stops working, then all thin clients connected to it will also not work. Despite these shortcomings, companies are increasingly using thin clients.

Remote administration

Remote administration is similar to working with a thin client in that a computer that has access to the server (client) can store and process data, and use programs on the server. The difference is that the client in this case is usually "fat". In addition, thin clients are most often connected to a local network, while remote administration takes place via the Internet. Remote administration has many uses, such as allowing people to work remotely on a company server, or on their own home server. Companies that perform part of their work in remote offices or cooperate with third parties may provide access to information to such offices through remote administration. This is convenient if, for example, customer support work takes place in one of these offices, but all company personnel need access to the customer database. Remote administration is usually secure and it is not easy for outsiders to access servers, although there is sometimes a risk of unauthorized access.

Do you find it difficult to translate units of measurement from one language to another? Colleagues are ready to help you. Post a question to TCTerms and within a few minutes you will receive an answer.

Today, the Internet is needed in every home no less than water or electricity. And in every city there are a lot of companies or small firms that can provide people with access to the Internet.

The user can choose any package for using the Internet from a maximum of 100 Mbps to a low speed, for example, 512 kbps. How to choose the right speed and the right Internet provider for yourself?

Of course, the Internet speed must be chosen based on what you do online and how much you are willing to pay per month for Internet access. From my own experience, I want to say that the speed of 15 Mbps suits me quite well as a person who works on the network. Working on the Internet, I have 2 browsers turned on, and each has 20-30 tabs open, while problems arise more from the computer side (to work with a large number of tabs, you need a lot of RAM and a powerful processor) than from the Internet speed. The only moment when you have to wait a bit is the moment the browser is first launched, when all the tabs are loaded at the same time, but usually it takes no more than a minute.

1. What do internet speed values ​​mean

Many users confuse Internet speed values ​​​​thinking that 15Mb / s is 15 megabytes per second. In fact, 15Mb / s is 15 megabits per second, which is 8 times less than megabytes, and at the output we will get about 2 megabytes of download speed for files and pages. If you usually download movies for viewing with a size of 1500 Mb, then at a speed of 15 Mbps the movie will be downloaded in 12-13 minutes.

We watch a lot or a little of your Internet speed

• The speed is 512 kbps 512 / 8 = 64 kbps(this speed is not enough for watching online video);
• The speed is 4 Mbps 4 / 8 = 0.5 MB/s or 512 kB/s(this speed is enough to watch online video in quality up to 480p);
• The speed is 6 Mbps 6 / 8 = 0.75 Mbps(this speed is enough to watch online video in quality up to 720p);
• The speed is 16 Mbps 16 / 8 = 2 Mbps(this speed is enough to watch online video in quality up to 2K);
• The speed is 30 Mbps 30 / 8 = 3.75 Mbps(this speed is enough to watch online video in quality up to 4K);
• The speed is 60 Mbps 60 / 8 = 7.5 Mbps
• The speed is 70 Mbps 60 / 8 = 8.75 Mbps(this speed is enough to watch online video in any quality);
• The speed is 100 Mbps 100 / 8 = 12.5 Mbps(this speed is enough to watch online video in any quality).

Many connecting the Internet are worried about the possibility of watching online video, let's see what kind of traffic movies with different quality need.

2. Internet speed required to watch online video

And here you will find out a lot or a little of your speed for watching online videos with different quality formats.

Broadcast type	Video bitrate	Audio bitrate (stereo)	Traffic Mb/s (megabytes per second)
Ultra HD 4K	25-40 Mbps	384 kbps	from 2.6
1440p (2K)	10 Mbps	384 kbps	1,2935
1080p	8000 kbps	384 kbps	1,0435
720p	5000 kbps	384 kbps	0,6685
480p	2500 kbps	128 kbps	0,3285
360p	1000 kbps	128 kbps	0,141

We see that all the most popular formats are reproduced without problems with an Internet speed of 15 Mbps. But to watch video in 2160p (4K) format, you need at least 50-60 Mbps. but there is one BUT. I don’t think that many servers will be able to distribute video of this quality while maintaining such a speed, so if you connect the Internet at 100 Mbps, you won’t be able to watch online video in 4K.

3. Internet speed for online games

When connecting home Internet, every gamer wants to be 100% sure that his Internet speed will be enough to play his favorite game. But as it turns out, online games are not at all demanding on the speed of the Internet. Consider what speed popular online games require:

1. DOTA 2 - 512 kbps
2. World of Warcraft - 512 kbps
3. GTA online - 512 kbps.
4. World of Tanks (WoT) - 256-512 kbps.
5. Panzar - 512 kbps
6. Counter Strike - 256-512 kbps

Important! The quality of your game online is more dependent not on the speed of the Internet, but on the quality of the channel itself. For example, if you (or your provider) receive Internet via satellite, then no matter what package you use, the ping in the game will be much higher than that of a wired channel with a lower speed.

4. Why do you need Internet more than 30 Mbps.

In exceptional cases, I might recommend using a faster connection of 50 Mbps or more. Not many providers in Kyiv will be able to provide such a speed in full, Kyivstar is not the first year on this market and it inspires confidence, the more important is the stability of the connection, and I want to believe that they are on top here. A high Internet connection speed may be necessary when working with large amounts of data (downloading and uploading them from the network). Perhaps you are a fan of watching movies in excellent quality, or you download large games every day, or upload videos or work files of large volumes to the Internet. To check the connection speed, you can use various online services, and to optimize the work you need to run.

By the way, speeds of 3 Mbps and below usually make surfing the net a little unpleasant, not all online video sites work well, and downloading files is generally not happy.

Be that as it may, there are plenty to choose from in the Internet services market today. Sometimes, in addition to global providers, the Internet is offered by local firms, and often the level of their service is also on top. I am served by such a small company. The cost of services in such firms is, of course, much lower than that of large companies, but as a rule, the coverage of such firms is quite insignificant, usually within a district or two.

Hello, dear readers of the site site!

You must have been interested baud rate over the network (including the Internet), write speed to a flash drive (or hard drive). Today we will deal with the speed of information transfer in computer technology and find out how many megabytes in a megabit!

You will need information from the previous lesson, if you have not read it yet, then be sure to start with it.

Let me remind you that in the last IT lesson we dealt with bits, bytes and multiple prefixes K, M, G, T and found out how many bytes are in a kilobyte (here's lesson 15).

Remembered? Then let's start!

Baud Rate - Units

The minimum unit of measurement for data transfer rate is bits per second, (which is not surprising, because a bit is the smallest unit for measuring the amount of information).

Bits per second or bps(in English bits per second or bps) is the basic unit used to measure the rate of information transfer in computing.

Since not only bits, but also bytes are used to measure the amount of information, the speed can also be measured in bytes per second. Let me remind you that one byte contains eight bits (1 Byte = 8 bits).

Bytes per second or Byte/s(in English byte per second or Byte/s) is also a unit that measures the speed of information transfer (1 Byte / s = 8 bit / s).

* I ask you to immediately pay attention that when reducing bits are written in small letters b» ( bps), a bytes capitalized " B» (M b/s).
