If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?
When a signal is received, the CPU suspends its current activity to process the request. The technique used in this instance is: A' Signal of Interrupt Spooling B C' Interrupt Handling D Polling.
Whenever the CPU receives a signal, it stops whatever it is doing to deal with the incoming request. So, here's how the mechanism operates: Spooling with B as the interrupt signal C as the interrupt handler D as the polling method A'.
As soon as an interrupt occurs, the CPU suspends the current process. This is interrupt service. Why is the present procedure suspended? Why not simply finish the present task and deal with the interruption later?

When an interrupt is received, the CPU immediately suspends the current process and begins responding to the interrupt. Is there a good reason to stop a running process? Because finishing the process of executing it and dealing with interrupts are mutually exclusive.
As soon as an interrupt occurs, the CPU suspends the current process and deals with the interruption. Interrupt service is the technical term for this. Why is the current procedure being halted? How about we just complete this process and deal with the interruption afterward?
When an interrupt occurs, the CPU immediately suspends the current process and deals with the issue. This is known as interrupt service in the technical jargon. What's the reason for the present process being halted?? Consider finishing the job now and dealing with the interruption afterwards.
When an interrupt occurs, the CPU pauses what it is doing and returns to work on serving the next process. Is a postponement of the execution required? Instead, how about simply carrying out the operation and leaving the rest to us?
The CPU suspends its present operation upon receiving a signal in order to reply to the request. How the mechanism operates: A' Interrupt signal Spooling with B' Interrupt handling C' Polling
When a CPU delivers an interrupt, it must stop whatever it is doing to reply to the signal. I'm curious about the reasons for stopping the procedure in order to complete the assignment. Let's start with the interrupting process and then go on to the executing process. explain?
Similar to Figure 5-24 on page 380, if the new requests come in for cylinders 5, 41, 20, 33, 8, and 13 while the seek to cylinder 11 is in progress, what are the total cylinders the disk arm should move to fulfill all the requests based on the SSF (Shortest Seek First) algorithm?
