Question 3: Task Manager

Using the Windows Task Manager, you can examine processes that are running, the number of threads a process has, system performance, and page faults.

Using Microsoft Windows operating system, follow these steps:

• Bring up the Task Manager by pressing ALT+CTRL+DELETE (if this step does not work, use the online help feature of the operating system to find out how to invoke the task manager). You should see a list of application and operating system processes currently running. Some of these names may appear cryptic; these typically make up a list of processes that are part of the operating system or automated environment.
• Start some application and you will see it added to the list of processes. You can also use the Task Manager to kill a process. This might be necessary if the process becomes "hung" or stalled, and will not respond when you try to close the application window. A stalled program is indicated by a "Not Responding" message after the process name in the Task Manager. Be careful, though: if you kill one of the operating system's processes, your computer may no longer function properly, although rebooting should correct the problem.

a. What is Page fault?

Here is what you need to do at first before answering the questions below:

If you are using Windows NT/2000/XP/7, follow these steps:

• Bring up the Task Manager window by pressing ALT+CTRL+DELETE and clicking the Task Manager button.
• Select the Applications tab. You should see a list of all applications currently running.
• Now select the Processes Tab. Then, on the View menu, click Select Columns, and check the Page Faults and Thread Count boxes. You can uncheck some of the other boxes if you wish. Then click OK.
• While keeping the Task Manager window visible (you may want to scroll down to the bottom if there is a long list of active processes), start up a new process, or make active a process that is already running. You should see the number of page faults and the CPU usage figures increase. Now click the Performance tab, and you will see graphs of processor and memory usage.

b. Run any browser on your computer (for instance, Mozilla Firefox) and Wordpad. Make the screenshot of your Task Manager, so I will be able to check if you really did it. Also answer these questions:

How many page faults (ошибки страниц) and threads (счетчик потоков) you can observe in your Task Manager for browser and Wordpad?
