Flashcards in Chapter 10 Deck (19):
1

What is a bottleneck?

A component that limits overall performance.

2

What is a baseline?

The 'normal' score created by your design specifications to compare to.

3

What is the Windows Experience Index?

A tool that scores your performance on a scale from 1.0 to 7.9.

4

When your system does not have enough RAM to perform an operation, what is used?

Virtual Memory

5

Where is virtual memory stored?

Your hard drive.

6

When your RAM runs low, where does Window move the data to?

A paging (or page) file.

7

What is the downside to virtual memory?

It is greatly slower than RAM.

8

The default paging file size is how many times the size of your RAM?

1.5

9

What gives you a quick glance at performance and information about programs and processes.

Task Manager

10

There are two keyboard shortcuts to access command prompt, what are they?

Ctrl+Alt+Del - then click Task Manager. Ctrl+Shift+Esc

11

What are they six tabs in Task Manager:

  1. Applications
  2. Processes
  3. Services
  4. Performance
  5. Networking
  6. Users

12

What is the % Processor Time

This counter measures how busy the processor is.

13

The processor may jump to 100% usage, the processor should never stay above?

80%

14

If your processor cannot perform fast enough, what should you do?

Use a faster processor or add additional processors or move some of the services to other systems.

15

What is Page faults/sec?

Attempts to access a virtual memory page that is not available in its working set in RAM.

16

If your Page faults/sec is 20 or higher, what should you do?

Increase the memory.

17

What is Interrupts/sec?

The numbers of interrupts generated by hardware the processor was asked to respond to.

18

What is ACPI?

Advanced Configuration and Power Interface

19

When you reduce power comsumption, what also gets reduced?

Performance.
