Another short paper in the Educause 7 Things series:
Skype is a voice over Internet protocol (VoIP) application that lets users make free phone calls between Skype-equipped computers and inexpensive calls between Skype computers and landline or cell phones. Skype functions on a P2P model rather than as a centralized application, and it offers features such as voicemail, call forwarding, conference calling, and video chat. In most circumstances, Skype provides access to voice and video communication for a fraction of what other options cost. It allows more frequent contact between colleagues, collaborators, and friends and permits connections with those not likely to be in conventional phone systems.
