Skype is an application that mainly allows Internet telephony through VoIP (Voice over IP). The app also allows the sending of messages, images and files in different formats. The program is enabled for free for various devices such as computers, smartphones or tablets. Skype It is a subsidiary of Microsoft since 2011.
The app Skype was founded in Luxembourg in 2003 by Niklas Zennström and Janus Friis. Building on the experiences that the two founders gained with other developers on the Kazaa file-sharing platform, they set up Skype as a peer-to-peer network.
During a session, there is a direct connection between the communication participants and only the resources of the respective devices are used. In this way, Skype saves infrastructure costs. The concept of distributed computer systems also has an impact on users, since video conferences, messages and files do not have to be transmitted to a server, as is the case, for example, with Google Hangouts.
Skype was acquired by Ebay in 2005 before the company generated a lot of interest from Facebook, Google and Microsoft. Ebay had sold most of its shares to an investment company. In conclusion, Skype became a subsidiary of Microsoft. The purchase price was $ 8.5 billion.

Once the user has downloaded Skype, they can use various tools. The mediation and transport of the data is carried out by means of the connection between different IP addresses. Only when the user logs in can he communicate with another user through the Skype server.
