What is the best internet connection? Available types of connections

Internet. How much he means today. Someone finds in it the means to earn money, someone finds salvation from loneliness. The Internet, these days, can be connected in several ways. Let's look at which methods are the most promising and convenient. So, which Internet is better to connect?

We connect the Internet: ways

  • The very first way to connect to the Internet was once a telephone modem. It is worth noting that this technology is outdated and cannot compete with the speed offered by a cable connection. But, again, once, this method of connecting to a virtual network was the only one.
  • The most common way to connect to the Internet - through the phone today - is ADSL technology. It is thanks to them that you can use the phone and the Internet at the same time. As a rule, the user connects a special ADSL modem, which is connected to the telephone network. The phone and modem are separated by a splitter, which allows you to use one telephone connection for two devices - a computer and a phone. This connection method for the first time allowed the creation of unlimited tariffs.
  • The next way to connect to the global network has replaced ADSL not so long ago. A wired internet connection allowed the user to completely separate the internet from the phone. Now, the phone is free from interference and load on the PBX, and the Internet flows through special wires that are brought to your apartment by a person representing the provider. Here is the best internet connection. What did this connection method give the user? The incomparably high speed of the Internet appeared precisely thanks to the wired Internet. The price of the internet has dropped significantly as more and more people have connected to the world wide web. A large number of providers appeared that provided Internet access, offering more and more favorable conditions to their customers. Today, it is the wired Internet connection that is the priority. This is the cheapest and most reliable way to connect to the global virtual space.

The latest connection technology is Wi-Fi technology. What does it offer the user? The main difference between Wi-Fi and, for example, wired Internet is freedom from unnecessary wires. In other words, your computer does not need any wire to connect to the Internet. You only need a Wi-Fi module that would be able to receive information from the Wi-Fi center. This technology was booming at a time when laptops were gaining popularity in the computer technology markets. The fact is that a laptop is primarily a mobile computer. Accordingly, it cannot be connected by any wires. The laptop must access the Internet through a Wi-Fi receiver, which has been implemented in recent years. However, it should be noted that Wi-Fi technologies cannot yet be compared in speed and reliability with wired Internet technologies, so Wi-Fi is convenient only in special cases.

The conclusion can be drawn as follows: today, the best connection to the Internet is a connection using fiber-optic communication lines. Here is the best internet connection.

To make secure purchases (transactions) on the Internet, you must be able to determine the "reliability" of sites. In real life, it is much easier to assess the "solidity" of a company or store than on the Internet. But how to determine the reliability of a particular site? How to correctly assess the level of trust in a particular Internet resource?

It's no secret that under the guise of a website of a real company (online store, etc.) the so-called "fake" (fake website-copy) can be hidden. In other words, Internet scammers copy the design, layout and content of the website of a real-life company (shop) and position it as real.

It is worth recognizing that for many people all sites are “one-stop-shop” and they can hardly distinguish a “one-day site” from a reliable Internet resource that has been successfully operating for many years. For this, it is important to be able to determine the "level of trust" to sites. This video tutorial will be dedicated to this topic. We will learn how to determine the "reliability" of any sites and learn how to distinguish a "fake" site from a real and reliable one. This is especially important when making any monetary transactions on the Internet.

I am sure that the knowledge from this lesson will help you protect yourself from various "divorces" and the so-called "scams". There are more and more scammers on the Internet who want to profit at your expense. Applying the recommendations from this video in practice, you will save not only your time, but also money.

The main topics of this video lesson:

  • How to distinguish a real offer from a scam?
  • Learning to determine the registration data of the site domain
  • What site data is most important for determining its "reliability"?
  • How to distinguish a real site from a fraudulent fake site?
  • Practical security tips or how to protect yourself from being scammed on the Internet?
  • We determine the level of trust (reliability) of a real site in practice

Video lesson number 3 - Determining the level of trust in sites

The connection between your computer and some site on the server you are browsing is not a straight line!

Therefore, when testing on the site, find the server from which testing gives the best result.

If there are communication problems, first of all check the contacts (network sockets, connectors, wires, routers, boards, etc.).
Windows network settings affect the speed of your Internet connection, but if you don't know what you're doing, don't do it!

Ping test.

Before testing the service to determine the quality of the network, the servers closest to you will be checked and the server with the minimum delay time in relation to your computer will be selected.

Rice. Screenshot of the test page to determine the characteristics of the network.

This test measures three indicators characterizing the quality of the network:

  1. packet loss- packet loss when receiving / transmitting from a server on the Internet and your computer. A good network is characterized by packet loss within 0%-1%.
  2. Ping- time spent on receiving packets from your computer to the Server on the Internet and back. Acceptable broadband connection quality should be less than 100 ms.
  3. Jitter- The result of calculating the difference when measuring successive pings. An ideal network is characterized by - 0 ms. In a real network, the ping difference is greater than zero.

YOUR GRADE and LINE QUALITY

Internet network quality classification:
  • A- Excellent. MOS is greater than 4.37. Ping below 50ms and 0% packet loss
  • B- Good. MOS from 4.28 to 4.37. Ping below 90ms and 0% packet loss. Network quality is not for all online games.
  • C - Satisfactory. MOS from 4.00 to 4.37. Ping below 150ms and 1% packet loss. Bad for online games and Internet telephony, for streaming video the quality of the Internet is acceptable.
  • D - Unsatisfactory. MOS from 2.50 to 3.99. Ping below 300ms and 3% packet loss. In such a network, all Internet applications will not work well.
  • F - Very bad. MOS is less than 2.50. Ping below 500ms and 20% packet loss. You should contact your ISP to correct the problem.

Note: MOS- Mean Opinion Score - an indicator of the quality of voice messages. In this case, it is determined by software methods and evaluated on a five-point scale. Best score - 5 points

We often turn to the Internet for help in searching for the goods we are interested in. And this is quite logical, because often it is online stores that offer us a lot of useful things, and are able to satisfy all our requests.

Increasingly, Russians make purchases in foreign online stores. At the time of the search, on the way of the buyer, both world-famous sales platforms and little-known sites often come across. They show great deals and the temptation of the buyer is growing.

When making a purchase in a domestic online store, we can choose cash on delivery and, if necessary, return the goods. In the case of foreign retailers, things are much more complicated, and buyers almost always expect a “pig in a poke”. Therefore, before placing an order, you need to make sure that a foreign online store is reliable.

How to evaluate the reliability of a foreign online store

It is not clear why, but for a long time the opinion has been established that in developed countries defective, faulty or counterfeit products are not sold. There is also an opinion that goods from abroad are necessarily of high quality. However, this opinion is not entirely correct, because even in developed countries, low-quality products can come across, and Chinese stores are "encrypted" under American and European ones. It is precisely such "honest" sellers that you should beware of.

First steps on an unknown site

1. First of all, when you go to the store website, familiarize yourself with its main subsections, carefully read the sections: “About us”, “Guarantees”, “Payment and delivery”. It is very good if the site has a section "Guarantees".

2. If, after reading all the information, you can evaluate it as plausible, then pay attention to whether there is technical support on the site. If there is one, then talk to the consultants and ask them everything in more detail: what delivery times they guarantee, how long they have been working in this area, and whether it is possible to exchange or return a purchase.

3. After that, it's time to move on to the next step: try to find real reviews about this store on the Internet. It is also not superfluous to check if the store is included in the lists of unreliable sellers. A single list does not currently exist, but many resources have lists of dishonest stores. Lists of unscrupulous traders are regularly updated.

Only an online store that has been operating for quite a long time can have a lot of reviews and a whole story. And if you see a young site, and it already has a lot of rave reviews, then this looks alarming.

How to check the reality of the origin of the site


In an attempt to sell their products, many sellers do their best to disguise their store as a European, American one. However, this information is easy to verify. To do this, you need to find the relevant data about the owner of the site and its location. To arrange such a check will cost you absolutely nothing.

To access the Internet, there are several ways to connect it, which differ from each other, in fact, by the connection technology itself, tariffs for use, as well as technical characteristics that determine the speed of information transfer, and the stability of the connection itself, and 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 quality of the Internet connection itself is the responsibility of the providers of this service - special organizations, the so-called providers.

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 that you can use wherever you are in the coverage area of ​​​​the provider (mobile operator). There are two connection options here: 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 via 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 Internet access wherever there is coverage of this operator. These are such technologies as: CDMA, WiMAX, LTE, UMTS. If the gadget is not equipped with a built-in modem capable of supporting these technologies, almost all mobile operators can offer their own branded plug-in modem.

The data transfer speed of these technologies can vary greatly in different user locations. However, now special Internet signal amplifiers are being produced that are capable of increasing this speed by several times.

3. Telephone connection (dialup)

This is by far one of the most common ways to connect to the Internet in Russia, but far from the best. It is used in the event that a landline telephone is connected to the apartment. By connecting a computer or laptop via a wired modem to a telephone line, you get access to the Internet. The phone at this time, of course, will be busy, and it will not be possible to use it until the end of the session on the Web. 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. WiFi

Wi-Fi (Wireless Fidelity) is one of the modern types of wireless communication. Almost all smartphones, tablets and laptops have a built-in special module that allows you to access the Internet while being in the coverage area of ​​Wi-Fi access points (usually the range is about 100 m). The Wi-Fi module can also be purchased separately and connected to a PC as a separate built-in board, or as an external device connected via USB.

So far, this type of connection is not in great demand among Russian users, despite the fact that many, by connecting a network Internet 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 rather an additional feature for the service business. Users can (as a rule, completely free of charge) have access to the Internet in various public places - at airports, train stations, cafes, hotels, gas stations, etc.

By itself, Wi-Fi technology 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 over a telephone line, while Internet access does not interfere with the phone's operation in any way. The quality of such a connection is an order of magnitude higher than with a conventional telephone connection. It has a high transmission rate 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 by a regular network cable. The advantages of this connection are its high speed, stability, reliability, and low cost. But this method is available, unfortunately, only in large settlements - where the cable lines of local providers pass.
