backup vs redo log files

Roger25Apr 9 2013 — edited Apr 18 2013

Hi,
Can anyone tell me what's the real difference between a backup file and a redo log file/archived redo log file and the scenarios (examples) when each of them can be used (for example, "......") ? Both are used for database/instance recovery. I have read the concepts of there 2 terms, but I need some additional information about the difference.

Thanks!
