What is Skype?

The best file-sharing service :) But seriously, it's free software that provides text, voice, and video communication over the Internet between computers.

There are alternatives to Skype, such as Discord, Viber, etc. ICQ also introduced a calling function for live communication and message exchange.

Downloading and registering for Skype will take 10-15 minutes, but it will save you a lot of time when communicating.
