Given the following set of events, show which routines the CPU is executing for times 0 to 100 ns. Each handler routine (with its interrupt request) takes 20 ns to complete. The priority of the interrupts ranges from IRQ6 as the highest priority interrupt to IRQ0 as the lowest priority interrupt. If an address bus needs to be able to address eight devices, how many conductors will be required? What if each of those devices also needs to be able to talk back to the I/O control device? Define the terms seek time, rotational delay, and transfer time. Explain their relationship. Suppose a disk drive has the following characteristics: 5 surfaces 1024 tracks per surface 256 sectors per track 512 bytes/sector Track-to-track seek time of 8 milliseconds Rotational speed of 7500 RPM. a. What is the capacity of the drive? b. What is the access time
