It’s hard to imagine the modern world without the Internet. Thanks to various search engines on the Internet, you can find absolutely any information and spend your free time playing exciting games online. In addition, through the World Wide Web you can use services that make our lives easier, namely: food delivery, taxis, courier services and much more.
Today, the Internet has already become a part of the life of a modern person. Almost all business and entertainment are connected in one way or another with the Global Network. However, to ensure connection, several conditions must be met at once. The topic of our conversation today: "What is an Internet connection? Types of connection, their advantages and disadvantages."
Via cable
Currently, this type of connection is most widespread. To connect to cable Internet, you need to contact the provider that services your home. He will extend a wire into the apartment through which the signal will go. Usually twisted pair or optical fiber is used for this purpose. Let's consider the features of these options.
twisted pair
In this case, a copper cable is supplied to your apartment from a distribution cabinet installed in the entrance, which is then connected to a computer or router. According to this principle, connections are usually made in apartment buildings. In this case, it is enough to simply determine what type of connection is installed in your home. If a thin wire enters your apartment, and the connection speed is on average up to 100 Mbit/s, then most likely you are using twisted pair. If the speed is higher and the cable is thicker, you probably have a fiber-optic Internet connection. Connection types can also be determined by other characteristics.
Optics
If an optical connection is used, a cable is inserted into the apartment and connected to a special distribution cable installed in the house. This type of connection has one very important advantage. The speed in this case can reach 1 Gbit/s. Using an optical cable, you can connect to the World Wide Web and use TV and telephone services. In this case, there is no need to run three wires into the apartment at once: one cord will be responsible for all types of connections. Cable Internet can work with network protocols using two protocols: local and virtual.
The local network
The principle of a local protocol cable connection is that your provider assigns you a separate IP. The communication provider unites all PCs into one common network, where each address is controlled. This type of connection can also be subdivided based on the use of static or dynamic IP. The easiest way is to use a dynamic IP address. The settings are carried out directly by the Internet provider. The user does not need to adjust anything.
How do you know what type of connection you have? If you just connected a cable to your computer and the Internet started working, then you have a dynamic IP. When using a static IPOC, you will be prompted for additional login parameters. In terms of providing access to the Internet, the static option is more complex. The system will ask you to enter data before each session. You can request all the necessary information for connection from your provider.
For services that always request a static IP, this address is preferable. How can you determine in this case that the static option is being used? In most modern routers through which the Internet connection is made, connection types are detected automatically. If you have a cheap or old router, then your provider can provide you with all the necessary data. Our specialists will also help you understand your specific device model. Judging by the reviews, providers mostly connect their clients via a static IP address. Rostelecom is engaged in the widespread implementation of “statics”. This is due to the fact that such a connection facilitates the process of monitoring each specific user. As for the quality of the connection, everything is largely determined by the type of cable and user equipment.
Virtual network
VPN, or virtual private network, works on the principle of using encrypted protocols. Data exchange between the provider and the user's PC is encrypted, increasing security on the Internet. There are only two main types of VPN connections - PPTP and PPPoE. One of the most popular protocols is PPPoE. To connect to the Internet, you will need a username and password. The Windows operating system recognizes PPPoE as a high-speed connection with conditional dialing.
PPTP is not widely used because it requires the user to enter the ISP's server address. A special feature of PPTP is its encryption algorithm. Which wired Internet operators in our country use this protocol? The most popular provider that uses it is Beeline. Reviews about this type of connection are quite mixed. Many people are not satisfied with the changing speed of data flow, but for others it is not critical.
FTTB
At the time of writing this review, the most popular type of Internet connection is FTTB. When using this type of connection, wired Internet operators install a switch in the house that interacts with the provider's station using fiber optics. A twisted pair cable is pulled to the subscriber’s apartment, which is inserted into the router or directly into the PC. In terms of price/quality ratio, this type is optimal. Access speed can be up to 1 Gigabit per second.
Using combined connection types
What types of Internet connections are there? A combined connection combines several types at once. In this case, the virtual network will have priority. Static and dynamic IP addresses can be used as additional resources. The difference between these types is the method of entering data about the provider’s server: manual or automatic. In reality, this type of connection is used quite rarely. It is often used in office networks with a multi-level structure.
Connection via telephone line
Surely many remember the times when Internet access was provided through a telephone. Today, fiber optic technologies dominate. However, to this day there are territories where, for a number of reasons, it is impossible to extend an expensive cable. In this case, having a home phone helps a lot. You can connect to the Internet via Dial-Up or ADSL. The latter allows you to work at low speeds of about 10 Megabits. This is enough to complete most tasks. To fully work with this technology, you will need a telephone cable and a modem. At the same time, if you want both your phone and the Network to work, you need to use a splitter. He is responsible for branching cables to the telephone and computer.
Internet access via Dial-Up connection can already be called a relic of the past. With this technology, the phone line will be busy if you are surfing the Internet. The connection speed will be only 56 Kbps. Today this is no longer enough. Despite all the shortcomings of this technology, there are simply no other options left in hard-to-reach areas. Judging by user reviews, when using this type of connection, even watching a video on YouTube becomes a problem.
Satellite Internet
Many people today are interested in how to connect the Internet via a satellite dish. Currently, this is one of the most expensive types of connection. However, you can install the plate almost anywhere. The main requirement is good visibility of the satellite. For most large operators this is not a problem.
A satellite dish is the optimal answer to the question: “Which Internet is better for a private home?” With the help of a satellite dish, you can easily access the Internet even in the wilderness, where there are no communications. Many people probably know on what principle satellite television works. The Internet through this device works according to the same scheme, the only difference is that a transmitter is additionally placed on the dish. This is necessary in order to ensure two-way exchange of information. Such a channel operates at a speed of several tens of megabits. The main disadvantage characteristic of this type of connection is the high price of equipment and maintenance. Tariffs for such Internet are simply exorbitant.
WiFi
Many people are probably familiar with Wi-Fi protocols and know first-hand what a wireless connection is. As a rule, Wi-Fi covers areas that are difficult to reach with cable connections. This type of connection is often used in cottage villages.
To provide Internet access, the provider installs base stations. They cover a network of approximately 5-10 square kilometers. To connect to the Internet, the user needs to use a receiver. If the client is located at a considerable distance from the station, he can use a special antenna that amplifies the signal.
A built-in Wi-Fi module is found on most modern electronic devices today. To connect them to the Network, you just need to select the correct position from the list and enter the password. This is why many clients today are trying to establish an Internet connection through a Wi-Fi router.
In addition, today some providers are trying to promote WiMAX technology. It is easily scalable and easy to deploy, but has not yet been widely adopted.
Conclusion
The Internet today has covered almost the entire globe. However, connecting it is not so easy. To gain access to the Network, you will have to use the services of one of the providers. Residents of large cities can choose from several connection options. In small towns or villages, as a rule, it is possible to connect to only one, maximum two providers. In this case, you can try to install the Internet via a satellite dish.
This review outlined the basic principles by which an Internet connection is made. Connection types were considered, indicating all the advantages and disadvantages. Which option to choose - decide for yourself. Don't just decide which type of connection suits you best. The financial component is also important.
To access the Internet, there are several ways to connect it, which differ from each other, in fact, in the connection technology itself, tariffs for use, as well as technical characteristics that determine the speed of information transfer, the stability of the connection itself, response time, and other subtleties . As you can see, the quality of the Internet depends not only on the hardware capabilities of the computer or mobile device used, as some believe. The providers of this service - special organizations, the so-called providers - are responsible for the quality of the Internet connection itself.
But, about everything in more detail - we will consider below the most common methods of connecting to the Internet, their features, advantages and disadvantages.
1. Satellite Internet
2. Mobile Internet
The name itself speaks for itself. This is the Internet, which you can use wherever you are within the coverage area of your provider (mobile operator). There are two connection options: via a mobile phone or via a special modem. The latter can be connected to a smartphone, tablet or laptop via USB ports (miniUSB) as a separate small device. Manufacturers often equip some models of computer and mobile equipment with such a modem.
Almost all modern mobile phones have Internet access. Somewhat outdated models are connected using slow and at the same time expensive GPRS technology. And for more modern mobile devices - smartphones and tablets - mobile operators offer high-speed connection technologies that can provide access to the Internet wherever this operator has coverage. These are technologies such as: CDMA, WiMAX, LTE, UMTS. If the gadget is not equipped with a built-in modem that can support these technologies, almost all mobile operators can offer their own branded plug-in modem.
The data transfer speeds of these technologies can vary greatly depending on the user's location. However, special Internet signal amplifiers are now being produced that can increase this speed significantly.
3. Telephone connection (dialup)
This is by far one of the most common methods of connecting to the Internet in Russia, but far from the best. Used if a landline telephone is installed in the apartment. By connecting a computer or laptop via a wired modem to a telephone line, you gain access to the Internet. The phone will naturally be busy at this time, and it will not be possible to use it until the end of the Internet session. And this is not the only drawback of a telephone connection - for example, this method of Internet connection is one of the most expensive, and perhaps the slowest.
4. Wi-Fi
Wi-Fi (Wireless Fidelity) is one of the modern types of wireless communications. Almost all smartphones, tablets and laptops have a built-in special module that allows you to access the Internet while within the range of Wi-Fi access points (usually a range of about 100 m). The Wi-Fi module can also be purchased separately and connected to a PC either as a separate built-in card or as an external device connected via USB.
So far, this type of connection is not in widespread demand among Russian users, despite the fact that many, by connecting an Internet network cable to a router, could freely move around the house with a laptop, tablet or smartphone and use the Internet. In Russia, Wi-Fi is more of an additional feature for the service business. Users can (as a rule, completely free) have access to the Internet in various public places - at airports, train stations, cafes, hotels, gas stations, etc.
Wi-Fi technology itself is quite fast, but due to the fact that access points are usually overloaded, the final speed sometimes leaves much to be desired.
5. ADSL
ADSL is a special type of Internet connection via a telephone line, and access to the Internet does not interfere with the operation of the phone. The quality of such a connection is an order of magnitude higher than with a regular telephone connection. It has a high information transfer speed and excellent stability.
6. Direct connection
This is the best way to connect to the Internet today. The user's computer is connected to the provider using a regular network cable. The advantages of this connection are its high speed, stability, reliability, and low cost. But this method, unfortunately, is available only in large populated areas - where the cable lines of local providers run.
Before you start setting up your router, it is advisable to find out the necessary information. We need to find out what Internet connection technology our Internet provider uses, we need to have the necessary parameters that will need to be set in the router settings (depending on connection technology). If, for example, the provider uses a connection using Dynamic IP technology, then you do not need any additional parameters. It’s enough to select Dynamic IP in the router settings, and the Internet will work.
You also need to find out whether the provider binds by MAC address. If it does, then after connecting the cable to the router, the Internet will not work even after correct configuration, because the provider does not have the MAC address of the router registered.
Now we will sort everything out in order.
The most important thing is to understand that the task of the router is to connect to the Internet and distribute it to your devices. It establishes a connection to your ISP in the same way as a computer. In order for the router setup to go smoothly and without problems, you need to correctly specify the connection type (WAN Connection Type) and set the necessary parameters.
What happens if you choose the wrong connection type?
This is the most common problem when setting up routers. The Internet will not work. The wireless network will appear, but after connecting to it, there will be no Internet on your devices. On computers, for example, the connection status will be “Without Internet access”. The Internet will also not work via cable from a router.
Everything is clear here, the router did not establish a connection with your provider because the parameters were set incorrectly.
How can I find out the connection technology my provider uses?
In Russia, Ukraine, and probably in other CIS countries, providers most often use the following technologies: Dynamic IP, Static IP, PPPoE, PPTP, L2TP.
- Dynamic IP– the most normal technology :) . A lot of Internet providers use it. We just connect the cable to the router and the Internet is already working, you don’t need to configure anything. You just need to specify the Dynamic IP technology. But, as a rule, it is set by default in the router settings.
- Static IP- not a very popular technology. To set up such a connection on your router, you must know the IP address that your Internet provider should give you.
- PPPoE– a popular technology (in Russia), which requires the creation of a special high-speed connection. If your provider uses PPPoE technology, then you most likely have created such a connection on your computer. In the router settings, you will need to select PPPoE, specify the login and password that your provider gives you. You may also need to set a static IP address.
- PPTP And L2TP– similar protocols, when setting them up you also need to specify a name and login. And also, the server address and, if necessary, a static IP. If the Internet was previously connected to the computer, then there was a special connection on the computer that you launched.
I have already written a lot, but still haven’t answered the main question.
Before you start setting up your router, be sure to find out what technology your Internet service provider uses.
How to find out? Call your provider's support and ask. Go to the provider's website and find instructions for setting up the equipment there. Or look in the documents you received upon connection.
If you call support, ask also whether the provider binds by MAC address, and what MTU value is best specified in the router settings.
If you already know the connection technology, then you should also know the necessary parameters. If you have a Dynamic IP, then, as I wrote above, no parameters are needed, but if you have, for example, a Static IP, PPPoE, PPTP, or L2TP, then you must know the login, password, static IP (if necessary), server address . Or only certain parameters (it all depends on the connection).
As a rule, this information is specified in the Internet connection agreement.
Is there a binding by MAC address?
Many providers tie the Internet to the MAC address of a specific network device. Each computer network card, or router, has its own MAC address, and this address is registered with the provider.
If your Internet provider makes such a connection, then even after correctly configuring the router, the Internet will not work. Since most likely, the provider has registered the MAC address of your computer, not the router.
What to do in such a situation?
Find out if binding is done by MAC address. If not, then no additional settings need to be made. If there is a binding, then in the router settings, you need . It is necessary that the router has the same MAC as the computer to which the Internet is connected. In articles on setting up certain routers, I try to write how to do this.
There is another option: look at the MAC address of the router (usually it is located on a sticker on the router itself), call the support of your Internet provider and tell them the new MAC to which you need to connect the Internet.
The key to successfully setting up a Wi-Fi router:
- Correctly specify the connection type and correctly set the necessary parameters (these are settings on the “WAN”, “Internet”, “Internet” tabs - different on different routers), which are issued by the Internet provider.
- Clone the MAC address, or register the MAC address of the router if the provider does the binding.
These are the two basic rules. Pay special attention to these two points and you will succeed. The main thing is that the router will already distribute the Internet, and then you can set up a Wi-Fi network, set a password, and other functions according to the instructions for a specific manufacturer or model. You can find these instructions on our website or on the Internet.
Internet access methods
The following methods of accessing the Internet are currently known:
Dial-Up(when the user’s computer connects to the provider’s server using a telephone) – dial-up access over an analog telephone network, data transfer speeds up to 56 Kbps.
DSL (Digital Subscriber Line)- a family of digital subscriber lines designed to provide access via an analog telephone network using a cable modem. This technology (ADSL, VDSL, HDSL, ISDL, SDSL, SHDSL, RADSL, collectively called xDSL) provides high-speed connections up to 50 Mbit/s (actual speed up to 2 Mbit/s). The main advantage of xDSL technologies is the ability to significantly increase the speed of data transmission over telephone wires without upgrading the subscriber telephone line. The user gains access to the Internet while maintaining normal telephone communication;
ISDN - dial-up access over a digital telephone network. The main feature of using ISDN is the high speed of information transfer, compared to Dial-Up access. The data transfer rate is 64 Kbit/s when using one and 128 Kbit/s when using two communication channels;
Internet access via dedicated lines(analog and digital). Leased line access is a method of connecting to the Internet when the user’s computer is connected to the provider’s server using a cable (twisted pair) and this connection is permanent, i.e. non-switched, and this is the main difference from regular telephone communication. Data transfer speed up to 100 Mbit/s.
Internet access via local network (Fast Ethernet). The connection is made using a network card (10/100 Mbit/s) with data transfer speeds of up to 1 Gbit/s on the backbone sections and 100 Mbit/s for the end user. To connect the user's computer to the Internet, a separate cable (twisted pair) is supplied to the apartment, while the telephone line is always free.
Satellite Internet access or satellite Internet (DirecPC, Europe Online). There are two types of satellite Internet access - asymmetric and symmetric:
The exchange of data between the user’s computer and the satellite is two-way;
Requests from the user are transmitted to the satellite operator's server through any available terrestrial connection, and the server transmits data to the user from the satellite. The maximum data reception speed is up to 52.5 Mbit/s (real average speed is up to 3 Mbit/s).
Internet access using cable television channels, data reception speed from 2 to 56 Mb/sec. Cable Internet (“coax at a home”). Currently, two data transmission architectures are known: symmetric and asymmetric architectures. In addition, there are two connection methods: a) a cable modem is installed separately in each user’s apartment; b) the cable modem is installed in a house where several Internet service users live. To connect users to a common cable modem, a local network is used and Ethernet equipment is installed common to all.
Last mile wireless technologies:
RadioEthernet, Mobile GPRS Internet
WiFi (Wireless Fidelity - accurate data transmission without wires) is a technology for broadband access to the Internet. The information transfer speed for the end subscriber can reach 54 Mbit/s. Their range of action does not exceed 50 - 70 meters. Wireless access points are used within an apartment or in public places in large cities. Having a laptop or pocket personal computer with a Wi-Fi controller, visitors to a cafe or restaurant (within the Wi-Fi coverage area) can quickly connect to the Internet.
WiMAX (Worldwide Interoperability for Microwave Access), similar to WiFi - broadband Internet access technology. WiMAX, unlike traditional radio access technologies, also operates on a reflected signal, outside the line of sight of the base station. Experts believe that mobile WiMAX networks open up much more interesting prospects for users than fixed WiMAX intended for corporate customers. Information can be transmitted over distances of up to 50 km at speeds of up to 70 Mbit/s.
RadioEthernet is a broadband Internet access technology that provides data transfer speeds from 1 to 11 Mbit/s, which is shared among all active users. For the RadioEthernet channel to operate, direct visibility between the antennas of the subscriber points is required. Range up to 30 km.
MMDS (Multichannel Multipoint Distribution System). These systems are capable of serving an area within a radius of 50-60 km, while direct visibility of the operator’s transmitter is not necessary. The average guaranteed data transfer rate is 500 Kbps - 1 Mbps, but up to 56 Mbps per channel can be provided.
LMDS (Local Multipoint Distribution System) is a standard for cellular networks for wireless information transmission for fixed subscribers. The system is built on a cellular principle; one base station allows you to cover an area with a radius of several kilometers (up to 10 km) and connect several thousand subscribers. The BSs themselves are connected to each other by high-speed terrestrial communication channels or radio channels (RadioEthernet). Data transfer speed up to 45 Mbit/s.
Mobile GPRS – Internet. To use the Mobile Internet service using GPRS technology, you must have a telephone with a built-in GPRS modem and a computer. GPRS technology provides data transfer speeds of up to 114 Kbps. When using GPRS technology, it is not the time of connection to the Internet that is charged, but the total volume of information transmitted and received. You will be able to view HTML pages, download files, work with email and any other Internet resources.
Mobile CDMA - Internet. The CDMA standard network provides landline and mobile communications, as well as high-speed mobile Internet. To use the Mobile Internet service using CDMA technology, you must have a telephone with a built-in CDMA modem or a CDMA modem and a computer. CDMA technology provides data transfer speeds of up to 153 Kbps or up to 2400 Kbps - using EV-DO Revision 0 technology. EV-DO Revision A technologies will allow subscribers to receive mobile Internet access at a speed of 3.1 Mbps.
In general, the Internet exchanges information between any two computers (PCs) connected to the network, which are often called Internet nodes or sites.(site – location).
There are two concepts used on the Internet: address And protocol.
Protocol– these are the rules of Interaction – the language of communication on the Internet. There are several layers of protocols that interact with each other. At the lower level, two main protocols are used: IP – internet protocol and TCP – transmission control protocol. They are united under the same name TCP/IP. All other protocols are based on TCP/IP.
When transmitting information, the TCP protocol breaks information into portions (packets) and numbers all portions. Further, with the IP protocol, all packets are transmitted gradually. After receiving all the parts (packets), TCP places them in the right order and assembles them into a single whole.
Hardware The component is represented by computers of different models and systems, communication lines. All components operate in a single network, both permanently and temporarily. Physical failure or temporary shutdown of individual sections of the Network does not affect the functioning of the entire Network.
Program component. Coordinated and joint operation of technically incompatible equipment is achieved thanks to programs running on PCs included in the Network. They allow you to transform data so that it can be transmitted over any communication channels and reproduced on any computer (PC). Programs have many functions: storing information, searching it, collecting and reproducing it, they ensure interoperability of all components of the Network.
Informational the component is represented by network documentation of the following types: text, graphic, sound, video (recordings) and can be distributed: text can come from some sources, sound from others, graphics from others. A certain information space is formed, consisting of hundreds of millions of interconnected documents. It looks like a spider's web.
The difference between the physical space of the Internet and the virtual information space of documents is manifested in different addressing systems. Every computer on the Internet has an address of four blocks, for example 193.29.137.31. This address is called an IP address. Computers on the Network on a permanent basis have a permanent IP address, on a variable basis - a temporary IP address for the duration of a given session, a dynamic IP address.
URLs (Uniform Resource Locator) are used for the information space. Each Internet user has his own unique URL, for example, the address of the “Teacher's Newspaper” http://www.ug.ru
Internet addressing
In order for the IP protocol to deliver packets to their destination, you must specify the address of the computer to which the data is intended. All computers connected to the Internet have unique addresses consisting of four integers, each of which does not exceed 256. When written, the numbers are separated from each other by dots, for example, 195.34.93.10 or 200.5.79.175. These are the addresses that are added to packets when sent over the network. While digital addresses are easy for computers to use, people find it easier to work with names. On the Internet, along with digital addresses, symbolic addressing is used. In this case, the conversion of a symbolic address to a digital one occurs automatically.
The postal address always contains the symbol @ , and the site address never contains this character. Attempting to send mail to an address ivan.cornpany.ru or go to the address [email protected] will cause an error.
Sign @ often called a "dog", although its correct name is "commercial at". Word at pronounced "et" and translated from English as the preposition "in". That is, the email address [email protected] means that the mailbox with the name myname located at the post office company.com. It can be difficult to master all the Internet addressing options at once. However, as you study the programs and surf the Internet, you will get used to the existing system and it will seem extremely simple to you. Plus, in most cases you won't have to manually enter addresses, you'll just click and load the page you want or select an email recipient.
Internet resources
On the Internet, the three components correspond to the following types of resources: hardware, software and information.
Hardware resources
Hardware resources are represented by backbone networks (Figure 12.9). By connecting to the Network, we actually use the hardware resources of the computer that provides this connection, the exploited physical resources of the communication lines. When overloaded, the data encoding time slows down, i.e. Each person makes the work of other Network participants more difficult.
Figure 12.9 Central European reference
Internet network
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 communication, 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.
