The Internet has long become not only the norm, but even a necessity in our lives. A lot of things depend on the use of the World Wide Web. But it is impossible to connect to it by simply plugging the cord into an outlet. Let's look at what types of Internet connections exist.

Over time, outdated Internet technologies are replaced by more advanced ones

Cable connection

Twisted pair and optical cable

This is the most popular connection type. A cable is installed in your apartment or office through which the Internet signal is received. There are two connection options: twisted pair and optical cable.

In the first case, a high-bandwidth fiber optic cable is installed from the service provider to the house or distribution box, and a twisted pair cable is installed into the apartment itself, which is a copper wire with a specially crimped end that is plugged into a computer or router. The connection speed in this case most often does not exceed 100 Mbit/s.

In the second case, an optical cable is installed in the home and connected to a distribution device. Among its advantages are much higher speeds, up to 1 Gbit/sec. Using this cable you can simultaneously receive Internet, telephone and television services - that is, one cable instead of three. Cable connection has two options for organizing a network: local and virtual.

The local network

The essence of a local network is that your provider assigns you a separate IP address. All computers, by and large, form a large network that has access to the Internet through a provider. There is access with dynamic and static IP.

Dynamic IP

This is the easiest type of communication for you. All settings for each connection are assigned by the provider, and you do not need to configure anything additional. You simply plug the cable into your computer or router and start using the Internet.

Static IP

With this type, the user needs to enter into the settings of the network card or router the parameters that are issued by the provider and which are unchanged during each communication session. This is quite convenient for online services that ask you for a permanent IP address. You can find out the type of connection in the provider’s technical support, on the service provider’s website, or in the contract. When using a router, most models can detect the connection type automatically.

Virtual VPN

VPN stands for “virtual private network.” This technology encrypts data exchange between the subscriber's computer and the provider's server, significantly increasing security.

The most popular type of VPN connection. To use you only need to know your login and password. The Windows operating system treats this connection as a broadband dialing connection.

L2TP/PPTP

Less popular types of VPN connections. In addition to your login and password, you need to find out the server address provided by your telecom operator. The only difference between them is the encryption method, which is selected in the additional connection settings. The most famous provider working with this standard is Beeline.

Combined connection

Combines several types of connections for accessing the Internet and provider resources. VPN is used as the main connection type, dynamic or static IP - as an additional one. The difference between them is the manual entry of a local address or its automatic determination. This connection is considered the most complex and is therefore rarely used. You can find out the parameters from the technical support of a specific service provider.

Phone line

Despite the fact that cable connections have recently dominated, in many areas it is not economically feasible to run a separate Internet line. In this case, it helps to have a telephone line; you can only connect to the Internet through it. There are two types of connection: ADSL and Dial-Up.

ADSL

Modern standards provide access to the Internet at speeds of several tens of megabits, which is quite enough for most tasks. The bottom line is that with the help of a splitter the signal is divided into different frequencies: low - for voice communications, high - for the Internet. Accordingly, you can make calls and use the Internet at the same time.

A modem is used to organize communication. The connection diagram is quite simple: the telephone cable, which is brought into the room, is connected to the splitter, and the home telephone and ADSL modem are connected to it in the corresponding connectors.

Dial-Up

This type of connection has come to us since the nineties of the last century. It is very outdated, since when used, the telephone line remains busy, and the average speed is about 56 kilobits. By today's standards this is very little. However, in some areas this type of connection is sometimes used.

It works as follows: the modem is connected to the telephone line and to the computer, and the modem pool number is added to its settings. The modem calls this number, and after the connection is established, the subscription gives you access to the Internet.

TV cable DOCSIS

This type of connection provides Internet via television cable. Undoubtedly, it is much more convenient to pay for the Internet and TV to one company. The cable is inserted into an apartment or house, and with the help of a splitter the signal is distributed to television and Internet. The Internet signal is sent to a cable modem connected to a PC or router.

Modern standards allow Internet speeds of up to 300 Mbit/sec. Despite the relatively low popularity of the technology, telecommunications service provider AKADO connects subscribers in Moscow, St. Petersburg and Yekaterinburg using it.

Mobile Internet

The development of 3G and 4G standards allows you to use the Internet at a speed comparable to a home connection. In many Russian cities, the 4G standard is available with speeds of up to more than 100 megabits. Where it is not available, 3G operates at speeds of up to 40 megabits.

Recently, unlimited tariffs have been offered, albeit rather conditional ones. No wires are needed and you can connect relatively cheaply anywhere where coverage is available. You can use a USB modem, mobile router or smartphone/tablet as a modem. The firmware can also determine network parameters.

Satellite Internet

The most expensive, but at the same time the most ubiquitous. Allows you to access the Internet even far from communications, even in the middle of the taiga. The only condition is visibility of the satellite.

Everyone is familiar with satellite television. Antenna dishes can be seen in almost every home and in huge quantities. The same dish is used to access the Internet. There is one-way and two-way satellite Internet.

With one-way access, outgoing requests are transmitted over a terrestrial communication channel, for example, through a mobile network, and incoming data comes from a satellite. With two-way access, all exchange occurs via satellite channel. To do this you will need an antenna with a transmitting head.

Access speed reaches several tens of megabits. The main disadvantage is the huge price for a set of equipment and rather high tariffs.

WiMax and Wi-Fi

Almost everyone is familiar with Wi-Fi; almost everyone has a router at home, and many public places have free access points. WiMax allows you to cover those areas where it is difficult to provide a cable connection in every home. This is applicable in the private sector or cottage communities. To provide coverage, base stations are used to provide coverage within a radius of several kilometers.

To connect, you need to have a special receiver, and when moving away from the station, an amplifying antenna. The technology is not widely used, since it still requires a cable connection to the village. It is much more expedient to use the mobile Internet.

Conclusion

We have listed all possible types of Internet connection. If you live in a city, most likely your provider will connect you via cable. This is the cheapest type of connection in multi-storey buildings. Equipment setup will differ for different types of connections; you can read more about this issue in our article How to connect the Internet on a laptop. In addition, never hesitate to contact the service provider's technical support to find out your network access parameters.

The most common ways to connect to the Internet today are:

• Modem connection (Dial-up) – Dial-Up, ADSL
• Leased line connection (fiber optic, etc.)
• GPRS – access (via cell phone)
• Radio access
• Satellite Internet

They all differ from each other in operating principle and data transfer speed., reliability, complexity of setting up equipment and, of course, price. The main characteristic of any Internet connection - data transfer speed - is measured in the amount of information transmitted to the user per unit of time (in one second) and is usually measured in kilobytes/sec (KB/s) or kilobits/sec (kbps). For high-speed channels, speed is already measured in megabits or megabytes per second.
In principle, spending time on the Internet can be divided into two groups - those that require receiving a large amount of traffic and those that do not require it. For web surfing (viewing pages), the speed of a regular modem connection is sufficient. However, this speed will not allow you to comfortably download large files - movies, high-quality music, and so on. Therefore, to fully use the capabilities of the Internet, high-speed access is required.

Modem connection (dial-up)

The oldest and most widely used connection method, but currently being gradually replaced by others. Modem (dial-up) connection is now relatively popular only in cities where there is no wide choice of providers.
With this connection method, each time the user needs to access the Internet, he will have to dial up the telephone line to the provider’s modem pool using a modem. This leads to the first disadvantage of dial-up - the telephone line is busy while on the Internet. Next, the provider processes the user's account name (login) and password and verifies them. Then the subscriber is assigned a free IP, thanks to which he gains access to the Network.
The advantages of such an Internet connection are: ease of configuration and installation of equipment (only an analog modem is required), low price of equipment, and many tariff plans offered by providers.
There are many more disadvantages to a modem connection. As noted above– busy telephone line of the subscriber, low data transfer speed (usually 3-4 KB/s), and poor quality of connection and data transfer due to worn-out telephone lines.
With the speed provided by a modem connection, it is almost impossible to download large files from the Internet - videos, distributions of large programs, and so on.

Required equipment

• Analog modem - from 300 (internal) to 1000 (good external) rub.
• Connection is free with most providers.

ADSL

ADSL (Asymmetric Digital Subscriber Line) technology is currently more promising than dial-up. This is a technology that allows you to provide high-speed broadband Internet access over regular analog telephone lines. The speed reaches 8 Mbit/s. In addition, this technology does not load the subscriber’s telephone line, thanks to the separation of signal ranges in the telephone line. The subscriber also does not need to call the provider. Disadvantages - quite high cost of traffic - 2-2.5 rubles / MByte.

Required equipment

• ADSL – modem (splitter is usually included) – from 600 to 2000 rubles.
• The right to connect for the population - up to 1000 rubles. (depending on the region).

GPRS connection

Due to the rapid development of cellular communications in Russia, almost every person has a cell phone. Why not use it to access the Internet? Almost all providers today offer the service of using a cell phone instead of a traditional modem. In this case, free channels of the cellular operator are used to access the network.
For the user, such an Internet connection is good because the phone supports GPRS The only additional equipment required is a device for connecting a mobile phone to a computer (USB cable, infrared port or Bluetooth). Another advantage is the mobility of this type of connection.
The data transfer speed depends on the cellular operator and the equipment used, but in general it is also low - only twice as high as a modem.
The defining disadvantage is primarily the high cost of traffic received by the user (5-7 rubles/MB).

Required equipment

• USB cable, infrared port, Bluetooth - about 400-500 rubles.

Leased line connection

The provider runs a dedicated line (twisted pair or fiber optic) to the subscriber's computer and issues a range of IP addresses for the subscriber to access the Internet.
At the same time, the user receives a free telephone line, constant connection to the Internet, high quality connection and data transfer, high speed (up to 100 Mbit/s).
However, the cost of installing and configuring such a connection directly depends on the distance of the computer to the connection point of the provider and, in any case, is quite large compared to other connection methods. And when moving the computer to another place, you will have to lay a cable to it again.

Required equipment

• In this case, the user only needs a network card from the equipment, and currently it is available on almost any motherboard.

Radio access

Wireless way to connect to the Internet. The provider and subscriber install all the necessary equipment (special radio modem, antenna), with the help of which information is exchanged between the user and the Internet.
The disadvantages of radio access are the need to purchase expensive equipment and high subscription fees to the provider. The quality of the connection and data transmission depends on the weather and visibility of the base transmitting station.
Its advantages include high connection speed (up to 2 Mbit/s) and subscriber mobility (that is, the ability to connect the subscriber device to another computer).

Required equipment

• Antenna - about 2000 rubles.
• Internal module (radio modem) – the price range is quite large

Separately, it is worth noting the Wi-Fi connection, which only requires a Wi-Fi module (costs up to 2000 rubles), but... in the regions there is practically no Wi-Fi coverage area.

Satellite connection

Satellite connection can be one-way (asynchronous) or two-way. The second one, due to the high cost of the equipment (the bill runs into tens of thousands), MirSovetov will not consider.
Most often, satellite Internet is called an asynchronous (or combined) access method - data reaches the user via a satellite dish, and requests (traffic) from the user are transmitted by any other connection - GPRS or via terrestrial channels (ADSL, dial-up). The main requirement for a request channel is connection reliability. In most cases, the best choice for this is an ADSL connection with free outgoing traffic.
Advantages of satellite Internet connection y - first of all, this is a very low cost of traffic - from 10 to 100 kopecks per 1 megabyte. The cost of a set of equipment and connection is currently affordable for almost everyone (especially compared to other access methods) and is approximately 200-300 US dollars.
Data transfer speeds vary significantly depending on provider and plan, selected by the user. Satellite Internet providers offer a very wide selection of tariff plans, including unlimited ones. A very nice bonus is also the possibility of free satellite television reception.
The disadvantage of a satellite Internet connection is the need the presence of a channel for outgoing traffic - a telephone line or a phone with GPRS support. However, now this is not such a big problem.

Required equipment

• Antenna 90 cm with bracket – about 2000 rubles.
• DVB card (satellite modem) SkyStar2 - 1800 rub.
• Converter – 700 rub.
• Cable – 100 rub. (10 m)
• Installation, configuration – 1700 rub.

It is worth noting that in large cities of Russia, due to growing competition among providers and the development of local networks, Internet access is becoming cheaper. Often you can install unlimited Internet access with decent speed and a subscription fee of 500-1000 rubles/month. In the provinces and small towns, this is much more complicated and prices are an order of magnitude higher. The best choice in this situation would be to use satellite Internet.
Finally, a little math. Let's calculate the approximate cost of downloading a certain amount of information from the Internet. When using modem (dial-up) Internet access with a time-based payment per hour, you can theoretically receive (download) 6 * 3600 = 21600 kilobytes, or 21 MB. In practice, this figure is in the region of 15-17 MB. Now let's count:
Modem (dial-up) access – 20 MB – 20 rubles (charge per hour).
ADSL access - 20 Megabytes - 40 rubles (Volgatelecom) (tens faster than modem access).
Satellite Internet – 20 MB – from 2 to 20 rubles depending on the download speed and time of day.
That's basically all, the choice is yours, enjoy your work on the Internet.

Currently, the main information space in which many events and operations take place is the Internet.

It is designed for searching information, communicating, working and spending free time. Nowadays it is available almost anywhere on the planet. The World Wide Web allows you to keep abreast of all events and news.

Few people now use communication via a telephone connection if they have the Internet at hand. You can communicate using various messaging programs.

Methods for connecting to the Internet

Today, the main types of Internet connections are

• wired,
• wireless and
• Wi-Fi.

They all have their positive and negative sides. In each situation, a certain type of connection is considered the most convenient. The choice of connection may depend on the user's activity, his needs and the purpose of the Internet. The location of the user (at home, on a trip, abroad) also matters, which influences the choice of connecting to the Internet.

Access the Internet using a cable (wired connection)

This method of accessing the Internet is perfect for those who like to download files and play games online. A wired connection has a high data transfer speed. It is important that this speed is equally fast for both receiving and transmitting information, which is not possible with other types of Internet connections.

Recently, optical fiber cables have begun to be used. It allows you to achieve the maximum speed by improving the quality of signal transmission.

A cable connection is most often used for desktop computer users who do not require constant movement, but can also be used for users of portable devices, laptops, and netbooks that have appropriate cable connectors.

This type of connection not only has high speed, but also the possibility of using unlimited tariffs. With this tariff, there is no limit on downloaded traffic, so you can use the Internet without restrictions and at maximum speed.

This type of wired connection is called by the abbreviation LAN. This is also the name of the connector in a PC to which you can connect a wire and provide wired access to the Internet.

Mobile Internet access (wireless network connection)

This type of Internet is very convenient for people who are constantly on the move. The main positive quality is the absence of a wire, which does not allow the user to move with his PC.

To access the Internet, you must have a special device inside your PC to work with a SIM card from mobile operators. And if you don’t have such a device, you need to have a special USB modem, which is produced by almost all mobile operators.

The connection to the Internet is carried out via mobile communications. To do this, you need to purchase an operator SIM card or the mentioned modem, and at the same time select the appropriate traffic size and tariff.

Tariffs can be either time-based (hourly, daily, monthly) or depending on the volume of information transmitted (for example, so many rubles for each megabyte of received or transmitted information). Time-based tariffs, as a rule, have a limit on the maximum amount of downloaded (transmitted) information. Once this limit is reached, the connection either stops altogether or continues at an extremely low speed.

It should be noted that recently operators have appeared that provide only Internet services, without telephony services. To communicate with such operators and to gain access to the Internet with their help, you also need data reception and transmission devices built into the PC or external USB modems, but SIM cards are no longer needed in this case.

The transmission speed of mobile networks depends on the capabilities of mobile operators. Today, standards such as 3G, 4G are used, and 5G standards are being developed. Each subsequent standard allows you to exchange data at ever-increasing speeds.

However, a mobile connection ensures that the speed of receiving data from the network to the PC is much higher than the speed of transferring data from the PC to the network, which is not very convenient, for example, when using Skype.

Internet access via Wi-Fi

Actually, this is also a wireless connection, but such a connection does not require modems. You just need to purchase a router that is designed to distribute radio waves.

Nowadays, many public places have Wi-Fi routers installed, which allow you to use the Internet at any time. This method of connecting to the network is very convenient for users of tablets, mobile phones or laptops that have a built-in Wi-Fi connection module.

This connection method is becoming increasingly popular. They are starting to use it both at home and in offices. The convenience is that you do not need to lay wires to computers.

It should be noted that Wi-Fi Internet connections are especially common in developed countries. There, access to the Internet via Wi-Fi is available almost everywhere. Thus, users of mobile gadgets can stay connected all the time, without interruptions. In our country, this connection method is also developing, however, given the scale of our country, mobile Internet access using a SIM card is still more reliable and more widespread in our country, including in rural areas.

All of the above methods of accessing the Internet have their own advantages, which allow you to choose the most suitable type of connection for PC users. Combinations of these methods are also allowed. For example, when using a laptop in a stationary setting (at work or at home), it is convenient to use a wired connection.

And when using the same laptop on a mobile basis, it is good to have a USB modem for connecting to mobile operators. When using the same laptop in a cafe, you can use a Wi-Fi Internet connection. So it all depends not only on the preferences of PC users, but also on the capabilities provided for connecting to the Internet.

Previously, people lived without telephones, computers, televisions, and obtained information and new knowledge from books, newspapers, and magazines. Today everything is much simpler and more convenient. To read a new book, watch a movie, find out show business news or approved laws in the country, you only need to connect to the Internet on a PC, mobile gadget or other device that has such capabilities. Connecting to the Internet today for many people serves not only as a means of communication, but also as a place of work.

To successfully use Internet services, you need the following components:

• PC, tablet, laptop, netbook, smartphone, etc.;
• a modem, which converts signals into information and transmits information into signals by sending them over a telephone line;
• software. Modern PCs already have built-in programs in the operating system that allow you to connect to the Internet. This also includes drivers (software package), browser;
• a communication line that transmits information without conversion using a modem;
• provider - a service provider who charges for connection time, volume of information, a certain period.

Important! To connect a personal computer to the Network, you need these devices and a specialist who can adjust all the settings.

Ways to connect to the Internet

New technologies and developments in this area make it possible to connect from a conventional modem to high-speed technologies. Methods of connecting to the Internet depend on the requested services, quality, speed, payment, etc.

You can connect the World Wide Web to your computer or laptop using:

• cable;
• modem;
• Wi-Fi.

Wired connection

A wired connection (often called “twisted pair”) has a number of advantages, which are expressed as a connection for a large number of equipment. It is convenient to use in offices, organizations and large institutions running on PCs.

The speed of information movement directly via optical cable reaches 1 Gbit/sec, and via twisted pair cable - 100 Mbit/sec. It depends on the type of cable and network card that receives the signal.

Other advantages of wired Internet:

• the speed is several times higher than via Wi-Fi;
• there is no delay when exchanging files or playing games;
• The signal quality is not affected by external factors.

There is only one drawback here - the presence of cables and cords.

Note! As a rule, developers of modern equipment and the latest technologies take care of the client’s comfort. Mobile gadgets and PCs do not require special settings; they are already built-in during assembly.

USB connection – modem

Since cables can hinder movement and clutter small spaces, there is a device for accessing the Internet without cable. This is a modem. It is designed to convert Network signals into information that is understandable to the devices that receive them.

Types of modems for Internet access:

• external (ADSL);
• internal.

Advantages of the modem:

• availability. Can work with any computer, laptop, netbook;
• practicality. Does not occupy processor resources during operation;
• quality. Excellent technical characteristics allow you to work quickly and efficiently;
• low cost.

It would take a long time to list all the advantages of modems, but there is no need. A user who has tried the device at least once will never give it up.

Since a computer or laptop loses its functionality and usefulness without turning on the Internet, and there is no Internet cable in the room, a modem will help eliminate this problem. To connect the modem to a PC or other device, you need:

1. Purchase a modem that satisfies the traffic, price, subscription fee, etc.
2. Turn on the PC and wait for it to fully boot.
3. Connect the modem to the device and press the ON button.
4. Load the installation disk into the drive and configure the drivers. If this is not possible, then most likely the settings have already been entered into the device and will be automatically unpacked.
5. A browser shortcut should appear on your desktop. By clicking on it twice, you should enter the provider data that the system requests (this is your login and password).
6. Launch any browser, making sure that the connection was successful.

Note! To check the device, it is recommended to go to the task manager and run diagnostics. If the settings were correct, then by clicking “Poll”, the diagnosis will be successful. Otherwise, a triangle with a yellow exclamation mark will appear.

Tunnel connection

Among other convenient methods, many users highlight the “tunnel”. The L2TP tunnel protocol is easily processed by network devices, reduces processor load and has a high speed of information flow and exchange. L2TP is an analogue of the old PPTP protocols from Microsoft and Cisco.

How to turn on the Internet on a Windows computer:

1. Open “Start” with the right mouse button.
2. Find “Network connections” and click on them.
3. In the “Settings” section, select “Network and Sharing Center”.
4. Select “Create a new connection or network.”
5. In the network settings, click on “Desktop Connection” and press Enter or “Next”. “Use my Internet connection” should appear.
6. Enter the server address, thereby allowing other users to use the connection.
7. Enter your username and code, connect to the Network and go to the “Network Connections” section.
8. Find "Properties" and open security settings. In the “VPN Type” section, click L2TP with IPsec (L2TP/IPsec). It is not necessary to specify anything in the “Encryption” field.
9. Enter the key (password) provided by the provider and verify authenticity.
10. To finish work.

Connecting PPTP on Windows

Going to the “Windows” settings, “Internet Network” section, you should select adding a VPN connection. Then enter your password and username. Through “Properties”, right-click to specify the point-to-point tunnel protocol and confirm the actions.

PPPoE connection

To connect the Internet to Windows XP, you need:

1. Go to “Start” → “Control Panel” → “Network Connections”.
2. In the “Create a new connection” window, select the “New Connection Wizard” destination.
3. By selecting “Connect to the Internet”, activate the menu.
4. Select “Set up a connection manually” and “Via a high-speed connection...”.
5. Enter the name “NETBYNET”, in the next window - login and password.
6. Confirm the above actions.

Connect via Wi-Fi

If there is a configured router in the room, then this option for connecting to the Network is the simplest. In just a few minutes you can set up the Internet and use its services.

Note! For a high-quality wireless connection, you need desire and a working device ready to receive the signal.

What you need to do to gain access:

1. Click on the wireless transmission module on the device.
2. In the “Managements” section, select “Network Connections”.
3. Select a wireless connection and activate it.
4. Enter the password (if the system prompts).

If you have the opportunity and desire to connect the router to a laptop or computer, then the steps are as follows:

1. Turn off the router, connect the cable to the device through the desired connector.
2. In the Windows menu, find “Network and Sharing Center.”
3. Select a local network connection, get an IP automatically (you should copy the displayed numbers - this is Static IP).
4. Enter the numbers 192.168.1.1 into the address bar of your operating system browser. In the field that appears, enter the login - admin and the password that is located on the router. Select a dynamic IP and click “Next”.
5. Enter your Wi-Fi name and password.

How to connect the Internet to a computer

There are also many ways to connect a computer or laptop to the World Wide Web using various devices. Each one can safely be called comfortable, practical and lightweight. But each user will choose for himself exactly “the one” that will satisfy all his requirements.

How providers connect the Internet

Those wishing to set up the Internet need a personal computer, a program for viewing content - a browser and a provider that provides Internet services.

The provider allows each user to identify themselves using a login and password. Different providers serve different geographies and provide different amounts of traffic, speed, etc.

To find a provider, you should first use word of mouth. You should find out what providers are already in the house (if it is a high-rise building), what is the quality of communication, what tariffs are better and other little things. You can also search for them on the Internet in special forums. There, according to user reviews, you can learn a lot of useful things.

How to connect a new PC to the Internet

The Internet can be connected to a personal computer through:

• cable;
• router;
• modem;
• access point;
• phone via bluetooth, USB cable (but the computer gadget must have 3G or Wi-Fi).

Step-by-step instructions for connecting a PC to a Wi-Fi router via a network adapter:

1. On the desktop in the lower right corner, click on the “Antenna” icon. A window will appear showing available networks and connections to them.
2. Select the desired network and click on “Connect”.
3. If the Wi-Fi is protected from “foreign” users, a window will appear in which you need to enter a password - a code that protects the provider.
4. After confirming the password, click on OK and you can safely use Internet services.

Note! If the “Antenna” label is crossed out with a red cross, then the laptop or computer does not see the network. In this case, it is worth checking whether the traffic distributor is enabled. But if everything is turned on, and the device model is old, the gadget may not support the Wi-Fi function.

The most common and convenient ways to connect to the Global Network are listed above. In city apartments and multi-storey buildings, cable connection is considered the most practical (from a financial point of view). You can install Internet by calling your ISP or contacting support. Well, for those users whose conditions do not allow using this method (they live outside the city), all that remains is to configure the Network only through a modem with a SIM card from a cellular operator.

Dial-up connection via modem. Today, the cheapest way to connect to the Internet remains access to the provider’s computer via analog and analog-digital telephone lines via a modem. The oldest dial-up method of connecting to the Internet has disadvantages: low speed and a busy line. The upper speed limit is 56 Kbps.

A dial-up connection via ADSL (Asymmetric Digital Subscriber Line) allows you to transfer data at speeds of up to 9 Mbps in the forward direction and 1 Mbps in the reverse direction over regular telephone lines.

A dial-up connection via ISDN (Integrated Services Digital Network) allows you to connect to the Internet over networks in which the access line to providers can be completely digital. This allows you to transfer a digital signal from one computer to another without conversion. Due to this, information is transmitted at speeds of up to 384 Kbps.

Connection via dedicated lines. You get the opportunity to use the Internet 24 hours a day without paying for the services of the telephone company at a temporary tariff. In this case, a fiber-optic cable is laid to the user's premises. The speed and quality of transmission over the channel in this case is guaranteed.

Connection via frame relay. When the information load on lines is uneven, it is often more profitable to use a connection via frame relay networks (“variable structure”). The principle of operation of such networks is simple: the minimum guaranteed channel capacity is determined, and if necessary, the bandwidth is expanded to possible limits. Such “forced” transmission of information is allowed if the line is not busy with other users. The expediency of using such networks in a small office, where the likelihood of simultaneous access to the network by several services is low, is obvious. From a financial point of view, a frame relay network is quite profitable.

Connection via cable television networks. If this technology is implemented, we immediately get a TV, telephone and Internet. Transmission speeds enable high-quality Internet telephony, real-time video conferencing, and broadcasting television programs on the World Wide Web. Data transmission is carried out through an HFC (Hybrid Fiber Coaxial) cable - a combined opto-coaxial cable. In this case, the data transmission protocol will remain IP (Internet Protocol) or newer protocols.

Connection via radio modem. This method will allow you to get rid of the telephone company.

Is becoming widespread Connectionvia mobile communication devices.

Internet services

Internet services usually refer to the types of services that are provided by servers on the network. The following are the oldest services available since the birth of the network:

1. Usenet (newsgroups, newsgroups) is an outdated service that allows you to organize network discussions on certain topics.

2. FTP - file transfer service) allows you to transfer and receive files from FTP file servers connected to the Internet.

3. Telnet - a service for remote access to computers.

4. Electronic mail (e-mail) - message transmission service.
