The Internet is an integral part of the life of a modern PC user. For some, this is a means of communication and a way of entertainment, and someone, using the global network, earns his living. In this article, we will talk about how to connect a computer to the Internet in different ways.

There are several ways to connect to the global network, it all depends on your capabilities and (or) needs.

• Cable connection. This is the most common and easiest option. The provider in this case provides the subscriber with a line - a cable brought into the room, which is connected to a PC or router. There are three types of such connections - normal, PPPoE and VPN.
• Wireless. Here, access to the network is carried out through a Wi-Fi router, to which the same provider cable is connected. Mobile 3G / 4G Internet can also be attributed to wireless methods.
• We will separately discuss the possibility of using a mobile phone as a modem or access point.

Method 1: Ethernet

This type of provision of Internet services does not provide for special access requirements - login and password. In this case, the cable is directly connected to the LAN connector on the computer or router.

In most cases, with such a connection, additional actions are not required, but there is one exception - when the provider provides the subscriber with a separate IP address and its own DNS server. These data must be registered in the network settings in Windows. The same will have to be done if there has been a change in provider, that is, find out which IP was provided by the previous one and given by the current provider.

1. First we need to get to the corresponding settings block. Right-click on the network icon in the notification area and go to "Network Control Center".

   

2. Next follow the link "Change adapter settings".

   

3. Here we right click on Ethernet and press the button "Properties".

   

4. Now you need to configure the TCP / IP version 4 protocol parameters. Select it in the list of components and go to the properties.

   

5. Checking IP and DNS data. If the provider provides a dynamic IP address, then all switches must be in the position "Automatically".

   

   If additional parameters are received from it, then we enter them in the appropriate fields and click OK. This completes the setup, you can use the network.

   

6. Ethernet has one feature - the connection is always active. In order to be able to disable it manually and do it quickly (by default, you will have to go to the network settings every time), let's create a shortcut on the desktop.

   

   Now, if the Internet is connected, then when we launch the shortcut, we will see a window "Status-Ethernet", where you can find some information and disconnect from the network. To reconnect, just run the shortcut again and everything will happen automatically.

   

Method 2: PPPOE

PPPOE is a high-speed connection, the only difference from the previous one is the need to independently create a connection with the given login and password provided by the provider. However, there is one more feature: PPPOE can compress and encrypt data. As already mentioned, access to the network also occurs using a cable connected to a PC or router.

PPPOE can be managed in the same way as Ethernet - using a shortcut.

Method 3: VPN

VPN is a virtual private network or simply a “tunnel” through which some providers distribute the Internet. This method is the most reliable in terms of security. In this case, manual creation of the connection and access data is also required.

This was an instruction for Windows 10, in the "seven" everything happens a little differently.

Method 3: WiFi

Connecting a computer to a Wi-Fi router is akin to a simple cable connection: everything happens as simply and quickly as possible. It just requires an adapter. In laptops, it is already built into the system, and for a PC, you will have to purchase a separate module. There are two types of such devices - internal, connected to the PCI-E connectors on the motherboard, and external, for the USB port.

It is worth noting here that inexpensive adapters may have problems with drivers on different operating systems, so carefully study the reviews about this device before buying.

After installing the module and detecting it by the operating system, a new network connection will appear in the notification area, with the help of which we will receive the Internet, just click on it and press "Connect".

Of course, the appropriate Wi-Fi network must be configured on the router. How to do this, you can read in the instructions that came with the router. Setting up modern devices, in most cases, will not cause difficulties.

Wi-Fi networks, for all their merits, can be very capricious. This is expressed in disconnections, lack of connection with devices and the Internet. The reasons are different - from problems with drivers to incorrect network settings.

Method 4: 3G/4G modem

All mobile Internet providers provide users with modems equipped with built-in memory with software written into it - drivers and a client application. This allows you to connect to the network without unnecessary gestures. When connecting such a modem to the USB port of a computer, you need to install the program and run it. If autostart of external devices is disabled in the operating system and the installer does not start automatically, then you need to go to the folder "A computer", find the disk with the corresponding icon, open it and run the installer manually.

To access the Internet, just press the button "Connection" in a programme.

If you do not want to constantly use the client application, then you can use the automatically created connection.

In the event that a new item does not appear in the list, you can create a connection manually.

Working with such a connection in Windows 10 is exactly the same as in the case of a VPN, that is, through the settings window.

In Windows 7, things are a little easier again. Open the list, click on the name, and then click the button "Connection".

Method 5: Mobile phone

If it is not possible to connect your PC to the Internet using the above methods, you can use your smartphone as a Wi-Fi access point or a regular USB modem. In the first case, a wireless adapter is required (see above), and in the second, a USB cable.

For normal operation of the access point, you need to make a number of settings in the phone menu or use a special program.

If the computer is not equipped with a wireless module, then there is only one option left - to use the phone as a normal modem.

Conclusion

As you can see, there are quite a few ways to access the global network from a computer and there is nothing complicated about it. It is enough to have one of the tools described above available, and also to perform if a few simple steps are required.

Types of the Internet - what are they?

Hello.

Are you going to change your provider or get another access point to the World Wide Web? Then you should know what types of the Internet there are, or rather, connections to it. The speed and convenience of work, as well as the amount you spend on connection and use, will depend on your choice.

The Internet has become so commonplace for a modern person that few people think about what kinds of it exist and how it improved to the result that we have now. Interesting to know? We read the article.

Wired connection

Let's start with the fact that you can connect to the global network using wires or without them. The first option, as a rule, implies a higher speed and stability of the connection. But, as you understand, it is suitable if you are going to use the Internet stationary. And there is? For you, I will talk about modern types of wired connections and what preceded them.

dial up

One of the most internet connections. Remember the times when users were on the Internet, and because of this, it was impossible for them to get through to a landline phone? They had a dial-up connection.

Physically, it looked like this: the subscriber had a modem that, when connected to the Internet, dialed the pool number and connected to the device at the provider's station.

The speed of such a connection was 56 kbps. Moreover, the tariff was determined not by the services provided, but by the time spent on the network.

It could even be half an hour.

xDSL (ADSL, VDSL, SHDSL)

First broadband internet. What does it mean? This type of connection is also implemented through a telephone line and a modem, or rather two. It is faster than its predecessor. Also, when a subscriber is surfing the Internet, he is also available by phone. This was made possible by separating frequencies for data transmission and conversations.

In the name of a family of technologies, the symbol "x" conventionally denotes the first letter of a particular subspecies. DSL from English stands for Digital Subscriber Line, which in translation is a digital subscriber line. Connection types differ in information encoding and data transfer rate. It is considered the most high-performance - up to 24 Mb / s.

As you understand, this connection no longer meets modern requirements, so now it is practically not found.

FTTx

This type of connection is the next stage in the development of broadband network after xDSL. It works according to the following scheme: in an apartment building or near private houses, a switch is installed, connected to the provider's station using a fiber optic wire; a twisted pair cable is connected to the client's house, inserted either directly into the computer or into the router.

Under the abbreviation FTTx, a family of Internet types is collected. It stands for "fiber to the x", which means fiber to the point "x". Instead of the last character, different letters can be specified:

• N (node) - network node.
• C / K (curb / kerb) - means: to the quarter, microdistrict.
• DP (distribution point) - distribution point.
• P (premises) - in general: before the premises. The most common option includes 2 subspecies: B (building) - the cable reaches the building boundary (foundation, basement, technical floor), H (home) - directly to the apartment or house.
• D/S (desktop/subscriber) - optical fiber is pulled into a media converter or terminal located near the subscriber's desktop.

E/Z (telecom enclosure/zone) - connection from the server room to the workplace.

The FTTx family is popular these days because it offers decent quality at an affordable price. Do you want to get high-speed Internet, television and telephone communications in one bottle? Choose this option. If all 8 cores in the cable are used and good equipment, your connection speed can be up to 1 Gbps.

Take a look at the alternative. With the help of fiber optics and twisted pair, a connection is made to the global network and through another technology - Ethernet, which also provides high-speed data transfer at speed. By the way, Ethernet subtypes have already been developed with indicators of 2.5, 5, 10 Gb / s and higher.

Another family of modern broadband connections. Depending on the connection method and Internet speed, other letters are written instead of “x”. The abbreviation contains the phrase "passive optical network", which translates as "passive optical network". In fact, it looks like a tree-like fiber-cable architecture with passive fanouts at the nodes.

Simply put, one transceiver module is used for many subscribers

The cable is laid directly to the client's home and is included in the media converter, terminal or sfp module of the switch. Hence, all its resources are used by one person. Therefore, Internet failures due to network congestion are excluded.

By connecting xPON, you will be able to use gigabit internet and other Tripple Play services (cable TV and telephony).

Satellite Internet

This type of Internet is also becoming a thing of the past, because it requires high connection costs. Judge for yourself: the subscriber needs to have at least an expensive satellite dish and receiver, as well as pay a lot to the provider for the provision of services. Although in return you get unlimited in tandem with digital television.

The organization of satellite Internet is carried out in two ways:

• Unilateral (asymmetric). Data is received via satellite and transmitted via either 3G/4G or cable.
• Bilateral (symmetrical). Reception and transmission of information is carried out through a satellite channel.

Nowadays, you can consider the option of connecting via satellite if the Internet is required, for example, in a remote village or a house in the forest. That is, where there is no opportunity to spend and poorly catches mobile communications.

Wireless connection

With the regular release of new products among smartphones and tablets, wireless Internet has gained popularity. Compared to a fiber-optic wired connection, it eliminates being tied to one place, but, as a rule, is inferior in speed.

This type of Internet can be divided into two main categories: the one provided by mobile operators and home or public through a WiFi router.

Mobile connection

It all started with GSM technology, which was developed for telephone conversations. When it was necessary to transfer data, an add-on for this channel appeared - GPRS: information is collected in packets and sent via unoccupied voice channels at a speed of 171 Kbps.

Very slowly, right? The developers also understood this, as a result of which they came up with another add-on - EDGE, which allows you to exchange data with a maximum speed of 474 Kbps.

3G

The needs of users were constantly growing, because of this, EDGE resources became insufficient. Thus, a technology was born that remains popular today. It provides speeds up to 3.6 Mbps.

To connect, you need a modem that is inserted into a computer or distributes the Internet via. Many gadgets have a built-in device for 3G. Services are provided, as a rule, by the same mobile operators.

This technology combines 5 data transmission standards, but CDMA (Code Division Multiple Access) is the most widely used.

4G

An advanced technology that has not yet displaced the previous generation due to insufficient number of coverage points and high cost. In 4G, the data transfer rate has been increased to 100 Mbps when traveling with a gadget, and up to 1 Gbps for landline subscribers.

This became possible due to the fact that communication is not divided into voice and Internet - only the latter is valid. In this case, there are also several standards: WiMax and LTE.

WiFi

Many people use this term daily, but few people know what it really means. The abbreviation was formed from the English phrase "wireless fidelity", which translates as "wireless fidelity".

But now “Wi-Fi” is used as a separate, independent concept.

This is most likely not a species, but a subspecies of the connection. Since this is a connection to an access point, or a communication transfer.

Among the wireless types of Internet, Wi-Fi is the highest speed (up to 100 Mbps). It is based on radio signals: they are supplied by the provider, and you only need to have a receiver. It can be a router, a special module for a stationary computer, a smartphone, a tablet, etc.

That's all.

I wish you pleasant communication and fruitful work on the Internet, no matter which type of connection you choose.

To connect the Internet in the house, you can use various options: cable Internet, wireless or finally satellite. Cable, that is, wired Internet will be available in areas where communications are developed. Usually, a wired connection can be made to each apartment at the moment - as a rule, there are already several providers for each address. But in rural areas, in gardening partnerships and dacha cooperatives, this opportunity is still rare. Usually users opt for 3G connection, although the signal is not always stable. But in this case, a minimum of equipment is required: just a mobile phone (or a 3G USB router). By the way, you can choose a suitable smartphone at the best prices in Ukraine at http://technoportal.ua/mobile.html. Satellite Internet does not differ in quality from cable, but will cost a little more - although two-way satellite communication has become available at the moment, connection remains expensive due to expensive equipment. About what equipment is needed for satellite Internet communications and how much it will all cost, we already wrote in a previous article. Therefore, today we will talk about wired Internet: what equipment is needed and how to connect. And let's briefly recall other connection options.

In principle, wifi in an apartment is easy to equip, having cable internet connected to the apartment. Therefore, we will consider the option of connecting to a wired Internet connection with the further arrangement of wireless communications in an apartment or house.

Necessary equipment for cable internet

The provider that provides you with a connection has all the necessary equipment to conduct, configure and test the connection. Here you need a copper twisted pair cable to bring the Internet to your apartment (or a fiber optic cable). Modern technologies are developing rapidly, so GPON (gigabit passive optical network) can be implemented by your operator. The essence of its work lies in the fact that in addition to the cable, a small box appears in your apartment, which allows you to connect to the network at a speed of 1Gbps. This despite the fact that usually this speed does not exceed 100Mbps.

So, the provider extended a cable to you. This is a dedicated Internet line and, as a rule, the operator provides unlimited Internet use. It will be the best option for both home and office. An Ethernet cable from a provider or can go directly to your computer - then no additional devices and other equipment are needed. Or it can be connected first to a router that distributes wifi around the apartment, and only then connect to a PC and mobile devices via cable or wirelessly. For the second option, you will need to purchase a wifi router and, possibly, a LAN cable and crimp it on both sides.

Why is this option with cable internet the best? The speed here is usually high and stable, the provider will offer you unlimited for a relatively low fee. Thus, using a router, you can set up home wifi and connect any mobile devices, TV, etc. at the same time, watch online videos, connect Internet TV service and watch channels in HD quality.

Mobile Internet

We are talking not only about 3G, but also about GPRS, EDGE. This option will be optimal for those who do not have Internet communications nearby, and there are also no other options such as telephone and television cables. For this option, you will need a special 3G USB modem, or a smartphone in which this modem is built-in will be enough (in fact, this function is available in any smartphone). In the modem, as well as in the phone, there is a place to install a SIM card, which also needs to be purchased. First you need to choose a provider (study the offered tariffs, and also don't forget to look at the signal coverage of your locality on the provider's website). A mobile provider may have different equipment, so this is what determines the communication technology (GPRS, EDGE, 3G or HSDPA (4G)). So, for this type of Internet, you need a router or smartphone, as well as a SIM card from your operator, a USB cable (but you can also connect via infrared or Bluetooth).

But this type of connection has its drawbacks. The main disadvantage is the instability of the signal. The speed can be high, but drop sharply due to automatic transition to another transmission technology. Typically 20-40 Kbps in GPRS, 100-236 Kbps in EDGE, 144 Kbps - 3.6 Mbps in 3G. But even if you connected to 3G, there is no guarantee that this speed is 100% provided to you, because when the 3G signal is lost, you automatically switch to a lower EDGE speed. The same is the case with 4G, where the speed can exceed 100 Mbps (and if you are also a landline subscriber, then 1 Gbps). It must be remembered that the speeds promised by the provider are just declared data. In fact, the data transfer rate via mobile Internet is very unstable and depends on many factors.

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

It is designed to search for information, communicate, work and spend free time. Now almost anywhere in the world there is. The World Wide Web allows you to keep abreast of all events and news.

Few people now use communication through a telephone connection if the Internet is at hand. You can communicate using various or messaging programs.

Ways to connect to the Internet

Today, the main types of Internet connections are

• wired,
• wireless and
• WiFi.

All of them 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 activity of the user, his needs and the purpose of the Internet. The location of the user (at home, on a trip, abroad) also matters, which affects the choice of the possibility of connecting to the Internet.

Internet access via cable (wired connection)

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

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

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

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

This type of wired connection is called the abbreviation LAN. Also called a 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 in constant motion. The main positive quality is the absence of a wire, which does not allow the user to move along with his PC.

To access the Internet, you need a special device inside the PC to work with the SIM card of mobile operators. And in the absence of 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 communication. To do this, you need to purchase an operator's SIM card or the mentioned modem, and at the same time select the appropriate traffic size and tariff.

Tariffs can be both time-based (hourly, daily, monthly) and depending on the volume of information transfer (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 (transferred) information. After this limit is reached, the connection is either disconnected altogether or continues at an extremely low speed.

It should be noted that recently there have been operators providing only Internet services, without providing telephony services. To communicate with such operators and to get access to the Internet with their help, you also need built-in data receiving and transmitting devices or external USB modems, but SIM cards are no longer needed in this case.

Transmission speed in mobile networks depends on the capabilities of mobile operators. To date, standards such as 3G, 4G are being applied, and 5G standards are being developed. Each subsequent standard allows you to exchange data at an increasing speed.

However, a mobile connection provides a much higher data transfer rate from the network to the PC than the data transfer rate 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 propagate radio waves.

Now in many public places Wi-Fi routers are 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 more and more popular. They are beginning to be used 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 connection is especially common in developed countries. There, access to the Internet using Wi-Fi is available almost everywhere. Thus, users of mobile gadgets can stay connected all the time, without interruptions. This connection method is also being developed in our country, however, given the size of our country, mobile access to the Internet using a SIM card is still more reliable and more common 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 appropriate type of connection for PC users. Combinations of these methods are also allowed. For example, when using a laptop in a stationary version (at work or at home), it is convenient to use a wired connection.

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

We will mention this type of connection purely out of respect for history: dial-up access was relevant at the end of the last millennium. To ensure communication, a telephone network and a modem were used, which was connected to the station's modem. The maximum possible speed was less than 58 Kbps, and the tariffs were extremely limited.

It is necessary to talk about xDSL mainly in a historical context, since at one time this technology was a breakthrough, but today it is of little relevance for residents of large cities. The maximum speed available to a leased line user is 24 Mbps. Compared to the dial-up access used before XDSL, the progress is clear. The advent of technology led to the transition from limit tariffs to unlimited ones.

FTTB (ETTH)

FTTB is the next technology after xDSL, which is currently the most widely used in the entire civilized world. The principle of operation is simple: a switch is located in the entrance, which is connected to the station of the Internet service provider. A twisted pair cable is connected to the apartment, which is connected to a PC or a special router. The main advantage is the favorable ratio between Internet speed and cost. The maximum possible speed is 1 Gbps.

The most progressive and modern method among the existing ones, involving the organization of a gigabit channel with Triple Play services. To ensure the connection, a special optical cable is carried out, which is connected to the appropriate equipment; converters, sfp module, optical terminals are used. In fact, xPON technology is gradually replacing FTTB, and the business Internet is often used by companies whose work involves the need to transfer large amounts of information.

Since almost every person today has a modern smartphone, mobile Internet is very widespread. It is pointless to discuss its advantages in detail because of their obviousness; the main plus is the ability to have an Internet connection literally “at hand”, the main disadvantage is limited limits. In recent years, the speed has grown significantly: if earlier GPRS and 3G were in use, today they have been replaced by 4G technology. The maximum speed of the latest LTE is 300 Mbps (theoretically); in fact, it is usually much lower. To organize the connection, USB modems and routers are installed.

Satellite Internet is another progressive branch, divided into two subtypes: one-way and two-way. The first - also called asymmetric - involves the use of communication with the satellite exclusively for receiving information, while conventional communication is used for transmission. The second - symmetrical - is more progressive, since it also allows the transfer of information, however, expensive equipment will be required to implement such a connection; the rates are also very serious. The only, albeit extremely significant, advantage is the ability to gain access anywhere in the world (up to the depths of the taiga).

The vast majority of modern devices - TVs, phones, smartphones - have a built-in Wi-Fi module that provides a stable connection to the Internet within a certain area. Large wireless networks are carried out mainly in large cities and in crowded places of a large number of people. The trend is towards WiMAX, which will replace conventional telecommunications due to ease of deployment and scalability.
