CIS 290 Week 4 Worksheets (Appendices F, G, & H)
Complete the following worksheets located in the appendices document on the student website:

  • Central Processing Unit Worksheet and Tech Paper (Appendix F)

  • Memory Worksheet and Tech Paper (Appendix G)

  • Hard Drive Worksheet and Tech Paper (Appendix H)


· Appendix F - Central Processing Unit Worksheet
·  
· The Central Processing Unit (CPU) is one of the most important parts of a computer system. It has a huge impact on the overall performance of any computer. If you have the opportunity, it is better to select the CPU before selecting the motherboard. Existing motherboards limit your choice of CPUs, forcing you to fit the CPU to the motherboard.
·  
· If the performance of the computer is crucial to the successful completion of a task, then choosing the CPU first is especially important; for example, if you are working on a computer that will be used for high-end graphics, the CPU’s speed needs to be greater than that used in a computer for general business applications.
· Research is important in determining the best CPU for your money. This can be done by checking your choices of CPUs against industry benchmarks.

  • Your employer has asked you to purchase and install faster CPUs into several of the company’s aging computers; however, you’ve only been given $180.00 per computer to work with. Using the computer featured in the Computer Hardware Simulator (CHS) as the one to upgrade, using the CHS motherboard to work with, search the Internet for two different CPUs that are compatible with the computer and enter information for each CPU into the chart below. Then choose which CPU and accompanying fan, if necessary, you would purchase and explain your decision.

· Appendix G - Memory Worksheet
·  
· Powerful Central Processing Units (CPUs) demand large amounts of data, and they need that data fast. Otherwise, the CPU performance is hindered by the lack of data storage support; therefore, computers have been designed to supply that data through tiering memory and caches, which use the hard drive in combination with RAM to deliver the massive amounts of data to the CPU. The speed of the RAM is crucial to the performance of data delivery, so you want the most RAM at the fastest speed possible so the CPU is not waiting for information.

  • Activity: Product Search


·  
· Without your knowledge, employees in your office have installed several new software programs on their computers. Everyone is now complaining that their computers are running slow. You have run some performance tests on the computers and have determined the problem is due to insufficient memory.
· As with other hardware components, it is important to know the computer’s memory requirements. For this activity, determine what types of memory are compatible with the office computers (they are exactly like the computer featured in the Computer Hardware Simulator (CHS). Then, search the Internet for two different types of memory and fill in information for each into the chart below. Make sure you install the maximum amount of memory possible and the fastest memory that the CHS motherboard supports. You want the best performance for these office computers, so memory price is not an issue.

· Appendix H - Hard Drive Worksheet
·  
· Hard drives are complex storage devices in a computer. When installing a hard drive, there are numerous interface standards to consider. You also must think about factors such as the computer’s application, the type of motherboard, speed and noise, GB barriers, subsystems, future storage needs, and archival issues. Refer to Ch. 8 of the text for a deeper understanding of these issues.
·  
· You can measure hard drive performance by looking at three different sources of information. The first is the data rate, which determines the number of bytes per second that the driver can deliver to the processor. The second is the seek time, which is the amount of time it takes when the processor requests information from the driver and the first byte of information is delivered to the processor. The third is the memory capacity of the hard drive.

·  
· For this assignment, you will be replacing the internal hard drive from the computer featured in the Computer Hardware Simulator (CHS).  The current internal hard drives are old and are starting to fail. You need to replace the current hard drives with similar drives or drives with more storage capacity. Search the Internet for three different types of hard drives that are compatible with the CHS computer, and enter your information for each drive into the chart below. After comparing the three drives, make a recommendation on which one you would purchase and justify your decision. You only have a budget of $45.00 to work with, so choose carefully.
