About Skype?

Skype is a leading Voice over IP service and software application that enables users to communicate with peers through voice, video, and instant messaging over the Internet. With Skype, users can make phone calls to recipients on the traditional telephone networks, and calls to other Skype users are free of charge. Calls to landline telephones and mobile phones are charged through a debit-based user account system. Skype operates as a hybrid peer-to-peer and client–server system, utilizing background processing on computers running the Skype software. The original proposed name, Sky Peer-to-Peer, reflects this unique approach. Skype is designed with security in mind, as encryption cannot be disabled and is invisible to the user. It is a trusted and reliable platform for secure communication, and continues to be a popular choice for individuals and businesses worldwide.
