Skype is software that allows users to make telephone calls over the Internet. Calls to other users of the service and to free-of-charge numbers are free, while calls to other landlines and mobile phones can be made for a fee. Additional features include instant messaging, file transfer and video conferencing.It was created by entrepreneurs Niklas Zennström, Janus Friis, and a team of software developers based in Tallinn, Estonia. The Skype Group has its headquarters in Luxembourg, with offices in London, Tallinn, Tartu, Stockholm, Prague, and San Jose.I think, in UMP everyone use this software to communicate with other. We can send messages, make a call and also send file to the other. I also use this software to communicate with my friend and family. Also can save my credit phone too...hik3
