Skype’s Underlying Peer-to-Peer Technology

So how exactly does Skype Download free enable low cost video calls between individuals across the world?

Unlike traditional phone services that route calls through central infrastructure and Private Branch Exchanges (PBXs), Skype is built using a decentralized peer-to-peer (P2P) networking model. This means Skype users connect directly to each other.
