All ways to connect to the Internet. Advantages and disadvantages
The World Wide Web is fairly short termhas evolved to the present scale. Almost everyone can afford to connect to the "web". Ways to connect to the Internet are diverse. If you read this article, then at least one of them is already familiar to you. Just over ten years ago, people could afford only 2 types of connection. Now you can count as many as eight (!). What are their differences, it is easy to disassemble, but extremely useful.
Let's start with the most "ancient". Legendary Dial-Up connection via a special modem. Today, this type can be found in places where, in addition to telephone communication, there are simply no other options to go online. The principle is simple. You need a modem and a telephone cable. The speed of this type of connection is incredibly low. While you are on the Internet, you can not get through to you. The telephone line is completely busy with data transmission. As a result, you pay both for using the telephone line, and for the Internet. Cases of communications failures and errors of connection to the Internet are quite frequent. In addition to the low cost of the modem and the simplicity of the connection, there are no obvious pluses anymore. Something to download from the Web, first, very long, and secondly - expensive.
Ways to connect to the Internet are being improvedevery day. The next step in the development already stands out in the background of Dial-Up. Meet the ADSL! It's all the same: a modem and a landline phone. But it also requires a special network card from the computer. The card costs "kopecks", modem about $ 15. High and stable speed, free phone line (even with a blocker) are the main advantages of this connection. The only drawback is the high cost of the provider's services. But there is an opportunity to use the Internet without any restrictions on traffic.
Increasingly popular is the connectioncomputer to the Internet through the phone. You can connect them together either through a straight cord (USB), or via Bluetooth and even an infrared port. High mobility and excellent speed made this connection at least convenient and interesting. But mobile operators in any way do not want to reduce the price for this kind of communication. The disadvantage is expensive.
Today you can often find a connection toInternet via cable TV. We need a special modem and the availability of cable television. Find out if you use cable network services, it is not difficult. Press the remote on the channels. If there are more than twenty, then all you have to do is solve the issue with the Internet provider.
The disadvantage is only in the price of the modem, but not infrequentlyransom is offered in installments. The subscription fee of this connection is low, the speed is excellent. Internet connection errors due to the fact that something is not connected there, just can not be. Include and work!
Have you met the word "vydelenka"? Most Internet users prefer this kind of connection. It is provided, thanks to a special network cable (twisted pair or "optics", ie fiber). This wire connects your computer to the equipment of the provider (source). Maximum stability of the connection is guaranteed. High speed also ceases to be an unfulfilled dream. Tangible flaws are not revealed. Inserted the cord into the computer - and there is an automatic connection to the Internet.
Often there is a situation when the providerthere is no way to conduct a cable to your home. But the ways to connect to the Internet are not limited to the above. The case comes wireless communication. On sale there are long-range antennas. They are capable of receiving / transmitting a signal for a distance of up to 5 km. You only need to point it at the access point. Disadvantages: the high cost of equipment, the maximum possible direct visibility between the antenna and the access point is required, the quality of the connection depends on the weather conditions, although the signal is not completely blocked due to this.
It is easy to afford to use freelyInternet, buying GSM or CDMA. It looks like a small "flash drive". Operators of mobile networks offer Internet connection services, and now even sell special modems separately. Inexpensive and very convenient!
There are also methods of accessing the network through satellites. Let not the most affordable, but extremely promising ways to connect to the Internet. Thus, you can get to the Network absolutely from anywhere in the world, but the prices for equipment are not decreasing yet and not everyone can provide such a service. Automatic connection to the Internet though from the wild desert, though from an uninhabited island.
