Difference between before and after trigger

If we want to update a field, for example case.status, which trigger is used? before or after insert? My understanding is that, "after insert" will be used since we are updating a field after the record is inserted.

Is that correct? Please help.

    Hi Chaitra,

    A trigger is the piece of code that executed before and after a record is Inserted/Updated/Deleted from the force.com database.

    Before Trigger: Before triggers are used to perform the logic on the same object and specifically we cannot use the DML operation (Insert, update, delete) on these triggers. These triggers fired before the data saved into the database.

    After Trigger: After triggers are used to perform the logic on the related objects and these triggers are used access the fields values that are created by system (Ex: CreatedBy, LasteModifiedBy , Record Id etc..).
