What is the difference between detach/attach and backup/restore?

What is the difference between an attach and a restore of a database?

When using ATTACH, you must have *all* of the physical files - SQL Server will know if you don't have all of them! Lastly, files that are being ATTACHed, are those that were previously DETACHed. RESTORE is a bit different in that it is used on a "backup set" - a single file that contains both data and logs.

What is difference between restore with recovery and restore with Norecovery?

We see the use of No Recovery command when there is the requirement of multiple backup restoration. In that case, With Norecovery option is used in all instances except the last one. Since With Norecovery command enables 'restoring state' in a database, additional backups can be performed.
