In the article we will talk about how Skype is made, what it is, what is its popularity, what is this program used for.
Communication without borders
Skype is a communication program built on the principle of exchanging instant text messages, audio and video calls. In a short time from the beginning of its existence, it replaced almost all competitors, it is used around the world, and versions for various OS and mobile devices have been released.
With the help of this program, you can communicate with its other users for free. You can also make calls to mobile and landline phones, but in this case, however, you will need to replenish your account with money, since such calls are charged. But how is Skype made? What principles is his work based on? This we will understand.
Program code
Any computer program consists of the language code in which it is written. After the final compilation, it is translated into a sequence of zeros and ones that the processor processes - in the so-called binary code. But we will not go into detailed technical descriptions.
So how does our program work, in simple terms? First, the user needs to register and create an account, its name will subsequently be a unique indicator, a kind of "phone number", which everyone is used to. After that, you need to install the program on the computer.
When a call is made to another subscriber, information with the user's login is sent to the program server to check its existence, then it is established whether it is on the network, and if so, whether it can receive calls.
If the subscriber answers the call, the program captures the microphone or video camera for subsequent conversion of the image and sound to binary encoding, sending the called subscriber to the server and computer, where it is transcoded again into picture and sound. The same thing happens with text messaging. As you can see, explaining how Skype is made is not so difficult.
Paid Calls
If calls are made to mobile and landline phones, then the system first checks the user's balance, and if the amount is enough, the request again “flies” to the program server, where it is forwarded to the mobile or city operator and their automated telephone exchange via a digital channel.
The same thing happens if one or both subscribers use mobile Internet for calls. During the conversation, the state of balance is monitored - and at the time of complete debit of funds, communication ceases. This is precisely the general answer to the question of how Skype works.
Skype and the State Duma
Several years ago, a very amusing bill was submitted by mobile operators for consideration, its purpose was to prohibit or restrict the use of Skype on mobile phones, since when using it for calls, the connection turned out to be cheaper.
Fortunately, no such decision was made. Otherwise, postal services, too, would very likely begin to ask to ban email.
How to make Skype on a computer?
To have Skype on your computer, you need to:
- Make sure that your device has the necessary equipment, such as a microphone and / or camera (the latter are usually supplied with an audio device, especially on laptops).
- Do not forget about the power of "iron". Of course, this program is quite democratic in terms of requirements, but on a very old computer it will work slowly and slow down the entire system.
- Then you need to proceed to its official website and download the latest current version.
- Then create an account, and you can start communication.
So we figured out how Skype was made, and learned the basic principles of its work.
