A. A system with three I/O devices: Printer, Disk, and DSL. The devices have interrupt priority with DSL being the highest, then Disk, and lastly Printer. It takes 12 seconds to process any interrupt. A User Program starts executing at t = 0 second. If a Printer interrupt occurs at t=20, and a DSL interrupt occurs at t = 22, and a Disk interrupt occurs at t = 24, and another DSL occurs at t = 38, when will the ISR for each interrupt completes execution? You may draw a diagram and then fill out the table. Device Type Interrupt Printer ISR Execution Occurs (request) at t= Starts at t= 20 Execution Ends at t= Activ 26.0
