== Hardware exceptions == {{Main|Interrupt}} There is no clear consensus as to the exact meaning of an exception with respect to hardware.<ref>{{cite web |last1=Hyde |first1=Randall |title=Art of Assembly: Chapter Seventeen |url=https://www.plantation-productions.com/Webster/www.artofasm.com/DOS/ch17/CH17-1.html#HEADING1-0 |website=www.plantation-productions.com |access-date=22 December 2021}}</ref> From the implementation point of view, it is handled identically to an [[interrupt]]: the processor halts execution of the current program, looks up the [[interrupt handler]] in the [[interrupt vector table]] for that exception or interrupt condition, saves state, and switches control.
