((("transactions","transmitting")))((("transmitting transactions")))Because the transaction contains all the information necessary to process, it does not matter how or where it is transmitted to the bitcoin network. The bitcoin network is a peer-to-peer network, with each bitcoin client participating by connecting to several other bitcoin clients. The purpose of the bitcoin network is to propagate transactions and blocks to all participants.

===== How it propagates
((("transactions","propagating")))Alice's wallet application can send the new transaction to any of the other bitcoin clients it is connected to over any Internet connection: wired, WiFi, or mobile. Her bitcoin wallet does not have to be connected to Bob's bitcoin wallet directly and she does not have to use the Internet connection offered by the cafe, though both those options are possible, too. Any bitcoin network node (other client) that receives a valid transaction it has not seen before will immediately forward it to other nodes to which it is connected. Thus, the transaction rapidly propagates out across the peer-to-peer network, reaching a large percentage of the nodes within a few seconds.
