Answers and Explanations
| 1. | B, D. The System Monitor can be used to track the performance of key system resources for both evaluation and troubleshooting purposes. If system performance is suspect but there is no clear indication of what might be slowing it down, the System Monitor can be used to determine which resource is operating at capacity and thereby limiting the performance of the system. Task Manager also has the facilities to provide real-time display of different system resources. |
| 2. | C. You should run the Defrag utility to optimize the storage patterns on the drive and thus improve read/write times and virtual memory performance. |
| 3. | A, B. The Windows 2000/XP Windows Disk Cleanup utility can be used to identify certain types of temporary files that are not required for operation of the system. The temporary files that you can normally afford to remove from the system to gain needed disk space include Windows, Internet, and multimedia temp files. Use the DEFRAG utility to realign files on the drive that may have become fragmented after being moved back and forth between the drive and the system. |
| 4. | D. You can increase the performance of Windows 2000/XP by manipulating the size and placement of its virtual memory swap file. Page file manipulation in Windows 2000/XP can be done in the Control Panel’s System icon. |
| 5. | B. To turn on Automatic Updates in Windows XP, access the System icon in the Control Panel and click the Automatic Updates tab. In Windows 2000, you can double-click the Automatic Updates icon in the Control Panel. In either operating system, Automatic Updates can be configured to download and install updates on a specified schedule or to notify the user when high-priority updates become available. You can click the Automatic (recommended) option button and then enter day and time settings for Windows to install the updates under the Automatically Download Recommended Updates for My Computer and Install Them option. |
| 6. | A. The Windows Update service is offered through the Internet and enables the system to periodically check the Microsoft Updates site for enhancements. When the system connects with the site, the service compares the current status of the local Windows installation to the latest information on the site. It then provides a list of available updates for the computer. Users can select which updates are applicable to their use. Users can also access the Windows Update service at any time through the Start menu or through the Internet Explorer Tools menu. |
