Answer 24

allows you to view information about the use of hardware (CPU, memory, disk, and network) and software (file handles and modules) resources in real time.

Question 25

What is page Fault /Sec?

Answer 25

A page fault occurs when a process attempts to access a virtual memory page that is not available in its working set in RAM. If the pages/sec is 20 or higher, you should increase the memory.

Question 26

What is Interrupts/sec ?

Answer 26

The numbers of interrupts generated by hardware the processor was asked to respond to. A sustained value over 1,000 is usually an indication of a problem including poorly configured drivers, errors in drivers, excessive utilization of a device, or hardware failure.

Question 27

Answer 28

Offers full performance when you need it and saves power during periods of inactivity. This is the best power plan for most people.

Question 29

What is the Power Saver Power Plan?

Answer 29

Saves power by reducing system performance and screen brightness. This plan can help laptop users get the most from a single battery charge.

Question 30

What is the High Performance Power Plan

Answer 30

Maximizes screen brightness and might increase the computer’s performance in some circumstances. This plan uses a lot more energy and will reduce the amount of time that a laptop battery lasts between charges.
