1-How can the CPU recognize the device requesting an interrupt? 2-Since different devices are likely to require different interrupt service routines, how can the CPU obtain the starting address of the appropriate routine in each case? 3-Should any device be allowed to interrupt the CPU while another interrupt is being serviced? 4-How can the situation be handled when two or more interrupt requests occur simultaneously?
