Fixing A Computer :: essays research papers

Fixing A Computer   Ã‚  Ã‚  Ã‚  Ã‚  Fixing computers is easy. The paragraphs to follow contain information on labeling parts, problems, and repairing vs. fixing. In these paragraphs will also compare a computer to the human circulatory system.   Ã‚  Ã‚  Ã‚  Ã‚  The internal parts of computers are very easy to recognize, once they are labeled. We will start by opening the case into the computer. Before opening the case don’t forget to have the computer turned off and unplugged, we don’t want to fry the computer parts. Once inside, we have a look around, and see a lot of parts that are unrecognizable to us. We will start from a top to bottom process of labeling parts. First look towards the bottom the big green board that everything else lies on is called the motherboard. A motherboard acts like the arteries of a human taking the blood all over allowing the blood places to travel, except the motherboard does this with electrical signals. The motherboard has three cards on it; they are the graphics card, sound card, and modem. They act like the voice, the eyes and the mouth of a human. You can tell the difference between them by how they connect in the back of the computer. The graphics card has a prong plug i n, the sound card has a place where speaker plugs can go and modems have a place where you can put your phone line. Next to the left of the cards we see there is a little chip with a fan on top, this is the processor. The processor acts like the heart of a human sending blood all over the body, but instead of blood the processor sends electrical signals. Straight above the processor in the little slot is the hard drive. The hard drive acts kind of like the brain of the whole computer, by storing information on it and sending and receiving electrical signals. Finally we have the cd-rom. This is located above the hard drive. The cd-rom is the mouth of the human. But the cd-rom takes in data instead of food. Next on the motherboard is three little chips, sitting next to the processor, these are called Random Access Memory, or RAM. The ram acts like the quick storage in the brain it remembers the stuff that you are working on right then. There now that we know the computers insides, I will give examples of problems and explain how to fix them.
