What is a previous transaction?

0

I'm new in the bitcoin field and I need to understand about transactions. When Bob is sending bitcoins to Alice, Bob will create a tx, he will add Alice's address, sign it and broadcast it in the network. But what is the previous transaction in this case? Is it a different tx from the one between Bob and Alice?

It's the transaction (or transactions) that bob got his bitcoins from.

What if that previous transaction is old? Does this matter? – anapaso – 2013-04-01T20:51:26.487

@user2016355 If the previous transaction is old, then the bitcoin network will give the new transaction special treatment. – Nick ODell – 2013-04-01T21:12:45.937

Thanks Nick. Is it possible to explain more? is there any link that I can read on the internet for that special treatment? – anapaso – 2013-04-01T21:19:42.223
