Appendix A - Computer Research Worksheet
 
Moore’s Law states that the number of transistors on a computer chip doubles every two years. This means that the power, speed, and application of computers are ever increasing. Along with these changes in performance, software is also improving, constantly pushing a computer’s capabilities to the edge.
As a computer technician, you must constantly stay up-to-date with these changes in technology. This includes understanding the dynamics of hardware and software and how they interact with each other. To stay current, you must include research as a necessary part of your job. With rapid changes going on in the computer industry, a technician needs to build a trusted network of information resources that includes websites, periodicals, and industry professionals.
 
Computer benchmark tests and tools are other resources you can turn to for computer information. In a benchmark test, the performance of a software application is measured when one brand of a hardware component is placed inside a computer. By using the same application and computer for each test, different brands of a component can then be compared with one another, allowing you to choose the best brand for the job at the price you want to pay. Benchmarks are a good way to get you started with your research, and you will be using them throughout this course.
 
To help you get started, here are some helpful websites:
 
· www.pricewatch.com: This is a helpful site to check pricing; however, be sure to look at the condition of the product. It can be listed as new or refurbished.
· www.tomshardware.com and www.kingston.com: These are benchmark sites to check out product performance.
· www.pcworld.com: This is a popular site for information and product reviews.
· www.ifixit.com and www.macfixit.com: These are helpful sites for troubleshooting.
 
Keep in mind that these are just a few of the many sites available for computer technicians. As you continue gaining experience, you develop your own network of trusted information resources.
 
Activity: Information Research

Appendix E - Power Supply Worksheet
 
When determining the type of power supply unit (PSU) needed to run your computer and all of its components, there are certain factors to keep in mind:
 
· Maximum Output – This is the number of watts the power supply is capable of delivering. The higher the wattage, the more power available. By determining the amount of wattage you need to run a computer, you could avoid spending more money than necessary on the power supply.
 
· Efficiency Rating – This determines how much energy your power supply uses to deliver the necessary wattage to run your computer. Most power supplies have an efficiency rating of 70% or higher at full load.
 
· Cooling – The more wattage there is, the more heat produced. The power supply should have at least one 80 mm fan to cool the system. Power supplies with over 400 watts should have two 80 mm fans or one 120 mm fan to effectively cool the machine.
 
· Power Connectors – Make sure the power supply comes with enough power connectors to run your computer. Refer to Ch. 4 of your text.
 
Activity One, Part A: Determining Wattage
 
Using the chart you created in Week Two’s Comparing Computers Worksheet, determine how much power you would need to run your dream computer. In the chart below, list the make and model of your computer’s components and research online to determine how much wattage is required to run them.

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.
·  

  • Activity: CPU Product Search

  •  

  • 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.

· 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.
·  

  • Activity: Product Search


·  
· 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.
