Most bitcoin libraries and frameworks do not store transactions internally as byte-streams, as that would require complex parsing every time you needed to access a single field. For convenience and readability, bitcoin libraries store transactions internally in data structures (usually object-oriented structures).
The process of converting from the byte-stream representation of a transaction to a library's internal representation data structure is called _deserialization_ or _transaction parsing_. The process of converting back to a byte-stream for transmission over the network, for hashing or for storage on disk is called _serialization_. Most bitcoin libraries have built-in functions for transaction serialization and deserialization.

See if you can manually decode Alice's transaction from the serialized hexadecimal form, finding some of the elements we saw previously. The section containing the two outputs is highlighted in <<example_6_1>> to help you:

==== Transaction Inputs
Transaction inputs identify (by reference) which UTXO will be consumed and provide proof of ownership through an unlocking script.
((("transaction", "outputs and inputs", "input components")))((("outputs and inputs", "input components")))Transaction inputs identify (by reference) which UTXO will be consumed and provide proof of ownership through an unlocking script.
To build a transaction, a wallet selects from the UTXO it controls, UTXO with enough value to make the requested payment. Sometimes one UTXO is enough, other times more than one is needed. For each UTXO that will be consumed to make this payment, the wallet creates one input pointing to the UTXO and unlocks it with an unlocking script.
