Lab 1.3.2 Determining Data Storage Capacity

Step 1: Identify the RAM in a computer

a. With Windows XP, there are two ways to view control panels: Classic View and Category View. The options available depend on which one of these two views you are using. If you see the Switch to Category View option on the left, you are currently in the classic view mode. If Switch to Classic View is displayed, you are currently in Category View mode. For this step, you want to use Classic View mode.

b. From the Start menu, select Control Panel. In the Control Panel, choose System to open the System Properties dialog box. Alternatively, you can get this information by clicking the Start button and right clicking the My Computer icon. Next, choose Properties from the drop-down menu. The computer operating system and service pack information are listed in the upper part of the dialog box. The computer processor type, speed, and memory are listed in the lower portion.

c. In this example, the computer processor is a Pentium 4 processor with a clock speed of 3.20 gigahertz (GHz). Clock speed is a measurement of the number of cycles per second that a processor is capable of doing. The number of cycles impacts the number of instructions per second that the CPU can process. A higher clock speed generally means that a processor is capable of executing more instructions per second. The computer has 448 MB of RAM available for the CPU.

d. Check your computer and determine the amount of RAM available to the CPU. How much RAM is in your computer?

(The computer has 965 MB of RAM available for CPU)

Step 2: Determine the size of the hard disk drive

a. Double-click the My Computer icon on your computer desktop. If you do not have a My Computer icon, click Start and choose My Computer.

b. Right-click the local disk drive under the Hard Disk Drives Section (which is usually the C drive), and select Properties. This opens the Local Disk Properties dialog box. The total capacity of the hard drive is shown above the Drive C icon.

c. Determine the size of the hard drive on your computer. What is the total size of the hard drive in GB?

(39.0 GB)

d. Keep the Local Disk Properties dialog box open for the next step.

Step 3: Determine the free space and used space on the hard drive

a. In the Local Disk Properties dialog box, the used and free space is shown in both bytes and GB
above the Capacity.

b. What is the used space of your hard drive in GB?          (21.3 GB)

c. What is the free space of your hard drive in GB?            (17.7 GB)

Step 4: Check for other storage devices

a. Right-click the Start button and select Explore.  Select My Computer in the left pane.

b. How many drive letters are shown in the window that appears?         (3)

c. Right-click on a drive icon other than C: and select Properties. The Removable Disk Properties window appears.

d. Select the Hardware tab, which provides information on each device and whether it is working properly.

Step 5: Reflection

a. Why is it important to know the amount of RAM in your computer?

b. Why is the size of a hard drive as well as the space being used important?

Lab 1.3.3 Determining the Screen Resolution of a Computer

Step 1: Determine the current screen resolution

a. To view the current screen resolution and color quality settings, right-click on any empty space on the desktop and select Properties from the context menu. In the Display Properties window, select the Settings tab. You can also access Display Properties by opening the Control Panel and clicking the Display icon.

b. Use the Display Properties Settings tab to record the current settings on your PC:
The screen resolution is (H by V)          (1280 by 800 pixel)
The horizontal resolution is:
The vertical resolution is:
The color quality value is:                        (Highest 32 bit)

Step 2: Determine the maximum resolution for the highest color quality

The slide bar under Screen resolution is used to configure the desired resolution.
a. Move the slide bar to see the range of screen resolutions that are available on your PC. (The range is determined by the operating system when it identifies the display card and the monitor.)

b. Use the Display Properties Settings tab to fill out the following table for the current settings on your

Step 3: Calculate the pixels for current and maximum resolution settings

The display on the screen consists of rows of pixels. The number of pixels in each row is the horizontal resolution. The number of rows is the vertical resolution. To determine the total number of pixels in a screen resolution, you multiply the horizontal resolution by the vertical resolution. For example, if the current resolution is 1280 x 1024, the total number of pixels is 1280 times 1024, or 1,310,720.

a. Calculate the total number of pixels for the lowest resolution:

b. Calculate the total number of pixels for the maximum resolution:

Step 4: Identify the type of graphics card installed

You can get detailed information about the graphics card (also called the display adapter) in the Display Properties screen.

a. In the Display Properties screen, click the Advanced button.

b. Select the Adapter tab.

c. Use the information found in the Adapter tab to complete the following table.

Step 5: Identify the type of monitor and available refresh rates

You can get detailed information about the monitor in the Display Properties screen. The screen refresh rate determines the number of times per second the screen is illuminated or redrawn. A refresh rate of 60 hertz means the screen is illuminated 60 times per second. Higher refresh rates provide less screen flicker, which reduces eye strain, but may adversely affect the monitor. You should set the refresh rate to the highest level the monitor can safel support.

a. Click on the Monitor tab to see the monitor type and current refresh rate.

b. Use the information found in the Monitor tab to complete the following table.

c. What can occur if you select a refresh rate that is higher than what the monitor can safely display?
