Skype is a software application that allows users to make voice calls over the Internet. Calls to other users within the Skype service are free, while calls to both traditional landline telephones and mobile phones can be made for a fee using a debit-based user account system. Skype has also become popular for its additional features which include instant messaging, file transfer, and video conferencing. The network is operated by Skype Limited, which has its headquarters in Luxembourg and is partly owned by eBay.
Unlike other VoIP services, the Skype company does not run servers, but makes use of background processing on computers running Skype software; the original name proposed—Sky peer-to-peer - reflects this.
