What is the best way to connect to the internet. How to choose the right internet connection

The existing opinion that “the faster the connection speed, the better”, of course, has the right to exist, but, unfortunately, there is a lot of confusion in this matter, as a result of which, a simple user pays not for the real speed on the Web, but “for air ".

Imagine that you have bought a car that can travel at a speed of 500 km / h, and all the roads that you meet on the way have a limit of 60 km / h. The question arises, was it worth spending money on such a car? The same is true when working on the Internet. Access to any site or resource is limited by the bandwidth of the channel through which this resource is connected to the World Wide Web, i.e. in fact - the speed with which the site will be able to give data to users connected to it. It is clear that the resource owner calculates the average number of visitors and, accordingly, pays for the minimum speed of access to his site required in this case. In the course of work, when the load on the resource is maximum, the speed of access to the site is significantly reduced and no longer depends on what speed the user will have to connect to the Internet.

In order to comfortably “surf” the Web (that is, navigate through the pages of sites), it is enough to have a connection speed of 1 Mbps. And similar programs that allow you to make video and voice calls over the Internet require a minimum and even less - 512Kbps for their stable operation. Network Internet games do not depend directly on the very speed of your channel, such a parameter as “ping” is important for them - the time it takes for a data packet to reach the game server from your computer and vice versa. If this time is minimal and stable (10ms-100ms), then even at low channel speeds you can safely play advanced online games.

The exception in this case is video content services - online cinemas and TV broadcasting sites, the access speed to which for comfortable and high-quality viewing can be several Mbps (2-8 Mbps). Theoretically, an ADSL connection can provide you with such an opportunity, but in practice, this opportunity often remains unrealized due to the poor quality of subscriber lines or its long length.

Always carefully read the contract that the provider offers you. Quite often there you can see that the connection speed is registered with the prefix "to". This suggests that the selected channel speed is not strictly guaranteed, and accordingly, you will not be able to present any claims to the provider on your part. For example, you have issued a connection with your operator at a speed of 1 Mbps, and during work you found that the real average speed of your connection is two times lower - 512 Kbps. If in your case the contract with the provider indicates the speed value “up to 1 Mbps”, you will not be able to make any claims.

With all the variety of choices

As a rule, today in the arsenal of most providers there is not one, but several types of Internet connections at once, which he can offer his customers a choice:

• ADSL connection (Asymmetric Digital Subscriber Line)
  One of the most common and massive connections to the Web today. It is carried out through a telephone line that you already have in your house or apartment. That is, in this case, both the phone and the Internet connection work on the same phone pair, and you can make calls and talk on the phone at the same time as you work on the Internet. If the telephone is not installed in your house and you do not need it, then providers, as a rule, have the ability to organize a “leased line” to your home without connecting to a PBX.

  ADSL connection has become so widespread due to its simplicity and fairly high speed. The theoretical speed that can be achieved with such a connection is up to 24 Mbps when receiving information from the Network to the Subscriber, and 1 Mbps when transmitting from the Subscriber to the Network. These data directly depend on the quality and length of your telephone line and in practice turn out to be much less. As a rule, the average, real speed in the line with an ADSL connection to the Subscriber is 10-14 Mbps, and outgoing - 700-900 Kbps.

  Thus, when concluding an appropriate contract for such a connection, compare the speed indicated in the contract with the speed of such a connection in practice and specify whether it strictly guarantees it. Otherwise, it may make sense to choose a slower and cheaper rate than paying for something that you will never get in practice. The disadvantages of this type of connection include low reliability due to work on a copper pair, the advantages - mass availability and loyal tariffs.

• FTTH connection (Fiber To The X; optical fiber to the "X" point)
  It appeared relatively recently and is available mainly to residents of multi-storey buildings, since laying fiberglass to private households is still economically unprofitable due to the high cost of this type of work. Today it is the fastest and most reliable connection to the World Wide Web. The connection speed can reach several gigabytes per second (in practice, so far - 1 Gb / s).

  Fiber-optic communication provides not only high-speed data transmission, but also a set of additional services, such as interactive TV, video on demand, and the like. In this case, the video can be transmitted in Full HD format. Unfortunately, due to the slow development of providers that can provide such video content, as well as the real bandwidth of Internet channels, the possibilities of this connection are still "idle" in most cases. But if the prices of your operator for an FTTH connection are low and you can afford it, then out of all the possible types of connections, you should choose this one.

• ETTH connection (Ethernet To The Home; translated as "Ethernet to the home")
  Great alternative to ADSL connection. Provides high speed (up to 100 Mbps) and good connection reliability. Just as in the case of an FTTH connection, it provides a large number of additional Internet services, including viewing videos in Full HD format (not to mention video calls on Skype). This technology is also available mainly for residents of "high-rise buildings".
• WiFi connection
  This is a wireless way to connect to the web. Basically, it is used by providers as free public access points and is practically not used as commercial access to the Internet. The reason is the dependence of this type of connection on the load, the more users - the lower the speed of Internet access. Theoretically, the data transfer rate in such a network can reach up to 108 Mbps, but in practice this speed does not exceed 4-6 Mbps, and it strongly depends on the number of simultaneously connected users.

  In addition, this technology is highly susceptible to interference on the air, since the frequency of such a network coincides with the frequency of operation of home and industrial microwave ovens. Additional interference in the working frequency channel is also introduced by the transceivers of Wi-Fi devices from other users. It is worth choosing this type of connection only if there are no other types of connections, i.e. as an alternative. Most often, this technology is used to connect household devices to a home network.

• Wi-Max connection (Worldwide Interoperability for Microwave Access)
  It is a modern development of Wi-Fi wireless technology, but with significantly improved performance. It is a wireless alternative to ADSL, but has a better and more reliable connection even over long distances. The data transfer rate in this case can reach 75 Mbps at distances up to 80 km. Due to the difficulties with the organization of infrastructure and the rapid development of fiber optic technology, it is mainly distributed only in large cities. This technology can be chosen as an alternative to an ADSL connection due to a higher quality of communication if the price for this type of service is comparable to the price of an ADSL connection.
• LTE connection (Long term evolution)
  “Long-term development” - this is how this type of connection sounds in translation. Today it has the highest data transfer rate of all available wireless networks. The bandwidth from the base station to the subscriber is up to 326 Mbps, and from the subscriber to the base - up to 172 Mbps. "4G" - this is how this new type of communication is called today. Communication networks of the 4th generation are just beginning to be built in Russia, but there is already a positive experience of their implementation and use. Thanks to the wireless method of data transmission and new technologies for transmitting and processing information, the connection in such a network has increased reliability and high data transfer speed, provides additional Internet services and mobility of the client terminal, that is, having such a connection, you can easily move around the city while working on the Internet at any point.

When choosing a connection to the Internet, you should always proceed from the realities of our life and clearly understand what you will pay your money for. It is hardly necessary to lay out a large amount of money just for the fact that a fiber optic connection at the local level will provide a seemingly gigantic speed of 1 Gbit / s, while the speed to the “outside” (outside the city, region or region), where we just work on the Web almost all the time, it is only a couple of megabytes.

The Skype program is not at all demanding on the speed of the Internet connection, however, to make sure that you will not have problems during calls, I recommend reading about Internet connection speed for Skype. But, as already mentioned, if you have the opportunity to use fiber - I recommend choosing this type of Internet connection and be sure that Skype will support all types of calls in the best quality.

Every day more and more devices are getting the opportunity to connect to the Internet. These are personal and mobile computers, servers and local networks, telephones, game consoles and music centers. Their access to the Web and services are provided by Internet service providers - organizations that provide Internet services.
Connecting to the Internet can be done in a variety of ways. The most common are:

1.Switched access via Dial-Up telephone line.
2. Access via digital subscriber line ADSL.
3. Access via a dedicated communication channel.
4.Wireless digital communication.
5.Wireless connection by mobile phone.
The conversion of information from digital form into electrical signals for transmission over communication lines and vice versa is carried out using a modem (short for the words "modulator-demodulator").
The choice of modem type is determined by the method of connecting to the network: analog - for a regular telephone connection, digital - for an ADSL connection, radio modem - for a wireless connection.
For personal computers, an internal modem is most often used, which is connected to a slot on the motherboard using a standard connector. Most modern laptops have a built-in modem.
An important characteristic of any computer network is the speed of information transfer, i.e. the amount of information that is transmitted per unit of time. The unit of transmission rate is 1 bit/s. The speed of information transfer in modern computer networks reaches hundreds of millions of bits per second. Therefore, derived units are used: kilobits per second or megabits per second.
With dial-up access over a telephone line, the modem, at the command of the computer, dials the provider's telephone number and, if the telephone line is not busy, establishes a connection with the provider's modem. Therefore, this connection method is called Dial-Up (on a call). The username and password are then checked. If the authorization is successful, the Internet connection is established. A temporary address is assigned to the computer for the duration of the session. During an Internet session, no one can reach the subscriber - the telephone line is busy.
The data transfer rate for analog modems reaches 56 kbps. The actual speed with dial-up access depends on many factors: the bandwidth of the external communication channel, the number of simultaneously connected users, the state of the telephone line.
The more users connect, the greater the bandwidth of the external channel should be. Therefore, the provider must have a multichannel telephone and a high-speed external communication channel, for example, with a speed of 30-60 Mbps and higher.
More promising is the ADSL technology (Asymmetric Digital Subscriber Line - asymmetric digital subscriber line), which allows you to transfer data over telephone networks at a speed of up to 8 Mbps to the subscriber and up to 1.5 Mbps from the subscriber (hence the name asymmetric).
The actual transmission speed depends on the length and quality of the line. Data exchange does not interfere with the telephone conversation due to the separation of signal frequency bands in the telephone line.
An ADSL connection requires a digital modem and a splitter.
Access via a dedicated channel is carried out by permanently connecting the user's computer to the provider's server. The provider conducts a dedicated line to the subscriber's computer and issues a permanent address. The user receives a constant connection to the Internet, high quality connection and data transfer, high speed (up to 100Mbps). Of the equipment, only a network card is needed.
The cost of laying a leased line depends on the distance to the connection point of the provider. For individual users, this method of access is justified only when the laying of the line itself does not require significant costs. The best option is to connect to home or city local networks, which provide general access to high-speed Internet connections. You can connect to such networks in various ways - in fact, these are ordinary local networks.
Recently, Internet connection via cable television networks has become widespread. There are two options. With an individual version, the cable modem is installed separately for each computer. With the collective option, one modem is installed in the house for several users. Then a local network is carried out and the necessary equipment is installed. Advantages: good speed, the ability to watch digital cable TV channels.
WiFi digital wireless communication allows you to access the Internet using a special adapter. It is built into most modern laptops.
There are several WiFi standards. They differ in data transfer speed, which can reach 50 Mbps. The actual data transfer rate is much lower, but this is enough for comfortable Internet browsing.
Using WiFi is possible if you are in the coverage area of ​​the receiving devices. Advantages: mobility, good speed, minimum equipment. Disadvantages: small radius of the coverage area of ​​one access point, the problem of line of sight, limiting the number of users in the WiFi coverage area.
Wireless connection to the Internet on a mobile phone is carried out using special mobile communication protocols.
One of the services of the most common communication networks at present is GPRS. The maximum data transfer rate according to the GPRS standard reaches 170 kbps. The real speed obsxyj does not exceed 30-40 kbps and depends on the workload and capabilities of the cellular operator's network, the distance to the antenna, and the characteristics of a particular mobile phone.
Sometimes GPRS networks are called second generation networks. Third-generation networks are also beginning to develop. For example, these include CDMA and EDGE mobile connection standards.

Nowadays, almost every resident of the country can afford the Internet. However, it can take a long time to connect to the Internet. In this article, we will provide instructions that will help you connect the Internet in just half an hour.

LAN connection

To connect to the Internet through local network, you need to have at least two computers, one of which will be the main server. You also need to create one workgroup. To do this, follow these steps:

1. Go to the control panel, go to system settings and click "Security".
2. Next, select "System", and in the new menu - "Advanced system settings".
3. Next, select the computer name and click the "Edit in a new dialog" button. Create a working group (you can choose any name).
4. Click OK. After that, you will need to restart your computer.
5. Now you need to set up a permanent IP address for both computers. To do this, you need to go to the control panel, go to the "Network" tab and select the "Network and Sharing Center" item.
6. Select "Change adapter settings", then "Network card" and right-click to select "Properties".
7. Now you need to set the visibility of the computer. To do this, go to the Internet menu, select "Network and Sharing Center".
8. Next, select the "Change advanced sharing settings" tab. In the profiles that open, you must select "Network discovery", as well as "File and Printer Sharing". Plus select "Sharing".
9. In order for network users to have access to all files and records, also check the box next to "Turn off password protected sharing."

Thus, we have considered how you can create a local network of two computers. Next, we will figure out in what ways you can still connect your computer to the Internet.

Leased line connection

In order to make such a connection, you will need to conclude a service agreement with the provider. As a rule, the company's specialist himself configures the connection. However, you can do it yourself using the instructions specified in the contract.

Connecting with a wi-fi router

If you have a wi-fi receiver, then using it and a network cable you can connect to the Internet and transmit a wireless signal to all devices equipped with a wi-fi module that is within the range of the signal.

Connecting with a USB tethering

In order to connect to the Internet using a USB modem, you must first purchase a modem with a SIM card from a mobile operator. This modem can be used both with a wi-fi router and with a computer. In the first case, you will be able to distribute a signal to all devices, while modern modems from mobile operators are capable of distributing not only 3g Internet, but also fourth-generation Internet, the so-called LTE.

You will need

• - computer - PC, netbook, laptop;
• – Wi-Fi router;
• – mobile phone supporting GPRS/EDGE/3G/4G networks;
• – USB modem.

Instruction

The most convenient and common way to connect to the Internet y is to use a USB modem. Purchase a device from any cellular service provider in your area and plug it into your computer's USB port. The driver installation and connection setup program will launch on its own, and after a short time, a message will appear in the taskbar stating that the device is installed and ready for use.

If autorun does not happen, open the media (My Computer folder, virtual CD-ROM denoting the modem), find and run the AutoRun.exe file yourself. Follow the prompts of the installer during the installation process.

Connection to the Internet using a mobile phone is somewhat more difficult. In order for a cell phone to be used as a modem, it must support packet data in the GPRS/EDGE/3G/4G format. This information is provided in the user guide for your phone. If support is available, enable it. To do this, dial a specific number on the phone, depending on the network operator, and press the call key. Save the settings that come in response.

Connect your phone to your computer using a cable, Bluetooth, or infrared. Insert a disc into the drive software and wait for it to start automatically. If the launch does not happen, do it manually by running the Setup.exe file, having previously opened the disk in Explorer. Follow all instructions of the installation wizard, which should install the driver for the cable, modem and create a connection.

If for some reason the automatic installation did not happen, open the "Phone and Modem" service in the "Taskbar". In the "Modem" option, start the manual modem installation process by pressing the "Add" button. The value of the APN access point, which you will need during the operation, can be found in the user manual or by going to the website of the telecom operator.

When the modem is installed, go to the "Control Panel" and open the "Network Connections" or "Network and Sharing Center" service - depending on which version of Windows you have installed. Run the New Connection Wizard and use it to create a connection to the Internet y, by double-clicking on it, you can access the the Internet. In case of problems, contact the mobile operator through its website or help phone. Support service or dispatcher will answer all your questions.

Connection to the Internet using a Wi-Fi router is as easy as using a USB modem. Purchase a router with a SIM card from a provider (cellular operator), insert the latter into the slot of the device and connect it to a computer via a USB port. The program will automatically establish a connection and make its settings.
