What's It Got Under the Hood? |  |
| Project Details |
|
We know that computers can do wonderful things. They can take us places we have never been (through the Internet), they can help us organize our lives, and they can help us to find and use information. Have you ever wondered how a computer is able to do all of that? To better understand computers it may be helpful for you to look inside and see what makes the computer work. This activity will help you to look under the hood of a computer and see what makes it run! |
| Do It |
|
This activity will require an old computer (it need not be in working condition) that you have permission to take apart. Be sure to check with the owner of the computer before you begin this process. Also, you will need some basic tools, like a screwdriver, a small pliers and a clean work surface. If a computer is not available for you to disassemble, try removing the cover from a working computer (NOTE: unplug the computer first and work with a helper) and finding the major parts. Record the make and model, type of processor, and the parts you are able to identify (see the checksheet in the DATA-BANK). Take a look at the schematic drawing of the inside of a computer-found in the DATA- BANK. Remember, your computer might be slightly different than the one pictured-but this drawing should give you an idea of what your computer will look like on the inside. The first step is to simply remove the screws that are holding the computer case together. After you have done that, the top of the case should slide off easily. Compare the inside of your computer to the drawing of the computer on the following page. What differences do you notice? Create your own drawing of the inside of your computer and label each of the parts. This will help you if you decide to reassemble your computer when you are done taking it apart. Carefully remove each of the components found inside your computer. Remember to be extra careful if you have plans to reassemble the computer. When you are done you should be left with a hollow shell where your computer used to be. |
| Review It |
|
Create a display of your disassembled computer. Label each part with its name and a basic description of the function of that part. Share this display with your project helper or with your 4-H club or class. Were you surprised at what you found inside the computer? What things did you not find that you thought that you would? |
| Pursue It |
|
Visit a computer repair shop and talk with a technician who works there. Ask the technician about the job and whether it is enjoyable. Spend time watching the technician work. Develop a worksheet page that would help other young people as they disassemble a computer. What do they need to be careful to do or not do as they work? Work with someone as they build a new computer. What are the advantages to building your own computer instead of buying one off the shelf? What special precautions do you need to take when doing this sort of work? |

 This drawing will help you to better understand what it is you find when you open up the box of a computer. Taking apart a computer can be a big job. Be sure that you have a good understanding of the parts of the computer before you begin your work. Information can be found at your local library or bookstore, as well as on the World Wide Web. Some helpful Web-based information can be found at:
