Diagram
A transaction is basically a series of inputs and a series of outputs.
In further detail; the transaction data tells you how to unlock existing packages of bitcoins (from previous transactions), and how to lock them up again in to new packages.
Notes
A raw transaction is sometimes called a “serialized transaction”, because it’s just a bunch of individual pieces of data zipped up in to one string of data.
