Skype is a tool owned by Microsoft where you can share messages, do a skype video/voice call and also share a computer screen while in the call.
The application is quite fast and has a very good UI and very user friendly as well.I have never faced any issues so far.
There is only one thing though, it sometimes slows down the pc. The application is heavily loaded and takes a lot of RAM memory, so for this make sure that you don’t keep the application on the startup of the pc, cause it will slow down the pc at startup.
overall great tool and great application, surely recommend to all the users.
