Lab 3

Step 1: Identify the RAM in a computer

·      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.

·      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 theStart 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.

·      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.

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

è   1,99 GB of RAM

Step 2: Determine the size of the hard disk drive

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

·                19,5 GB

2.      What is the used space of your hard drive in GB?

·                8,06 GB

3.      What is the free space of your hard drive in GB?

·                11,4 GB

Step 4: Check for other storage devices

4.      How many drive letters are shown in the window that appears?

·           Five drive

Step 5: Reflection

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

è  RAM is the actual workarea. All the calculation are the calculation are done in CPU and result and data is stored first on RAM and yhen transferred to harddisk. So it is the most important one.

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

è  The size of hard disk and the space used is important only for those who were running out hard disk space and not or those who don’t have enough data to upload on their hard disk so the size of the hard disk and space used is important depending upon how an individual use the hardisk space
