Suppose that you are designing a game system that responds to players' pressing buttonsand toggling joysticks. The prototype system is failing to react in time to these input events,causing noticeable annoyance to the gamers. You have calculated that you need to improveoverall system performance by 50%. This is to say that the entire system needs to be 50%faster than it is now. You know that these I/O events account for 75% of the systemworkload. You figure that a new I/O interface card should do the trick. If the system'sexisting I/O card runs at 10 kHz (pulses per second), what is the speed of the I/O card thatyou need to order from the supplier?
Suppose the daytime processing load consists of 60% CPU activity and 40% disk activity.Your customers are complaining that the system is slow. After doing some research, youhave learned that you can upgrade your disks for $8,000 to make them 2.5 times as fast asthey are currently. You have also learned that you can upgrade your CPU to make…
Since the CPU clock is written, it cannot be modified, and electricity cannot be changed either. To put it another way, what actually occurs?
We know the CPU is printed and the electricity speed cannot be modified, but what will happen to the real components of the computer if we try to modify the clock speed anyway?

- When does failover processing run? What methods do you know for it?arrow_forwardWhen the CPU clock speed is printed, there is no way to modify it since electricity cannot be altered. To put it another way, what takes place in practise?arrow_forwardThe connection between the CPU and memory should be made via an asynchronous or synchronous bus. Do you have a justification for your response?arrow_forward
- It is impossible to modify the speed of the CPU clock since it is printed and electricity cannot be altered. In other words, what's the truth behind it all?arrow_forwardThere is no way to alter the CPU's clock speed since it is printed and electricity is fixed. To put it another way, what is the truth?arrow_forwardYour computer is acting funny. Sometimes you get an error message on the screen. Other times data seems to be corrupted. Sometimes the computer just locks up. You suspect that it may be bad memory. How can you find out whether a memory problem or something else is causing your trouble?arrow_forward
- 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?arrow_forwardSince the CPU's clock speed is printed and electricity is immutable, it cannot be altered. To rephrase: what really occurs?arrow_forwardThere are numerous instructions that must flow through the CPU at the same time. In what ways does this method rely on certain components? In what ways do you see them having an impact?arrow_forward
- What would happen to the actual parts of the computer if we tried to change the CPU's clock speed, knowing that the CPU is printed and the electricity speed cannot be changed?arrow_forwardShould the bus between the CPU and RAM be synchronised or not? Which is better? Explain your pick.arrow_forwardMistakes are snafus. Why aren't there any interrupts in the hardware?arrow_forward
