Objectives
  • Determine the amount of RAM (in MB) installed in a PC.
  • Determine the size of the hard disk drive (in GB) installed in a PC.
  • Determine the used and available space on the hard disk drive (in GB).
  • Check other types of storage devices (floppy, CD-ROM, DVD).
Background / Preparation
The storage capacity of many PC components is measured in megabytes (MB) and gigabytes (GB). These components include RAM, hard disk drives, and optical media, such as CDs and DVDs. In this lab, you will determine the capacity and space available for various computer components.
The following resources are required:
  • Computer with Windows XP installed
Step 1: Identify the RAM in a computer
  1. 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.
  2. 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.
  3. 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.
  4. Check your computer and determine the amount of RAM available to the CPU. How much RAM is in your computer?jawaban:  956 MB atau 1GB.
Step 2: Determine the size of the hard disk drive
  1. 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.
  2. 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.
  3. Determine the size of the hard drive on your computer. What is the total size of the hard drive in GB?  The answer will vary depending on the hard drive installed in each computer. Jawaban: 34,1 GB
  4. 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
  1. In the Local Disk Properties dialog box, the used and free space is shown in both bytes and GB above the Capacity.
  2. What is the used space of your hard drive in GB? Jawaban : 17,1 GB
  3. What is the free space of your hard drive in GB? Jawaban : 17,0 GB
  4. The answer will vary depending on the space of each individual hard drive.
Step 4: Check for other storage devices
  1. Right-click the Start button and select Explore. Select My Computer in the left pane.
  2. How many drive letters are shown in the window that appears?  Jawaban: 3
  3. The answer depends on the hardware installed, but there will be at least one and most likely two (hard drive and CD/DVD drive). There could possibly be more if there is a floppy drive, a USB flash drive, or a network drive.
  4. Right-click on a drive icon other than C: and select Properties. The Removable Disk Properties window appears.
  5. Select the Hardware tab, which provides information on each device and whether it is working properly.
Step 5: Reflection
  1. Why is it important to know the amount of RAM in your computer? Jawaban: This will determine the type of OS that you are able to run as well as which application programs can be used. Generally the more RAM in a computer system the better
  2. Why is the size of a hard drive as well as the space being used important? Jawaban: The size of the hard drive gives an indication of the total number of files that can be stored on the drive. This includes the operating system, application programs as well as any data associated with these programs. Generally the larger the drive size the better.
