Computer Interrupts Quiz

An interrupt is an event that temporarily suspends the execution of a main program to execute a special routine that services the interrupt. Once the interrupt processing is complete, the processor is returned back to the exact place in the main program where it left off.

An interrupt might occur when a timer interrupt service is executed while the processor is in a word processing application and performing a spell check. The activity of spell check is temporarily suspended until the interrupt is serviced.

The Pentium microprocessor can respond to 256 different types of interrupts.

<p>The two types of interrupts mentioned are external interrupts (hardware interrupts) and internal interrupts (software interrupts).</p> Signup and view all the answers
