is there a difference between a select statement inside a transaction and one that is outside of it

Question

Does the default READ COMMITTED isolation level somehow makes the select statement act different inside of a transaction than one that is not in a transaction?

I am

Answer 1

The READ COMMITTED isolation level is about the records that have been written. It has nothing to do with whether or not this select statement is in a transaction (except for those things written during that same transaction).
