Also referred to as: The heart of a Computer – allows the various parts of the computer to communicate with one another CPU (Microprocessor) Called the “Brains” of a computer – Controls all of the other parts of the Computer. The processing time of this chip is measured in megahertz. One megahertz = One million cycles per second. Expansion Cards A circuit board that can be placed in the PCI or AGP slots on the motherboard. Examples of these are: Video Card, Sound (Audio) card, NIC (network interface card), FireWire ports card. Heat Sink A metallic device mounted over the CPU to draw heat away from it to keep it from overheating. Most heat sinks have metallic prongs attached to them to further dissipate the heat away from the CPU. IDE Cable Integrated Device Electronics. This is a cable that looks like a wide ribbon. It connects the hard drive to the motherboard. RAM Random Access Memory. A board made up of small memory chips. The motherboard has expansion slots specifically for “RAM Banks” • Volatile memory – data is lost when main power to computer is turned off Peripheral Devices Devices that are outside of the computer, but are plugged into an available port on the computer. Common peripheral devices are: keyboard, mouse, speaker, printer Power Supply Converts external power – regulates and distributes appropriate power throughout the PC Hard Drive An input and output device that stores program and data files used by a PC Optical Drive Uses a light reader (laser) to record and store information, e.g., a DVD/CD-ROM R/W IT: Computer Maintenance: Inside a PC Plan Copyright © Texas Education Agency, 2011.

Determine who goes first (coin toss, draw straws, etc.) 4. First team captain selects a letter from one of the “Select” columns (A-H). 5. Teacher reads the question or definition corresponding to the letter on the Match Game Terms Sheet. Do not read the term in italics. 6. First team must give the answer that matches the question or definition. Captain gives the answer. 7. Teacher clicks on, and moves, the covering text box to the right or left side of the grid to reveal the answer. (Left side for first team; right side for second team). 8. If the answer revealed is not the same as that given by the first team captain, the teacher recovers the square with the text box and play goes to the second team. 9. If the answer is the same as that given by the first team captain, the first team has the opportunity to select a letter under the “Match” columns (I-P). Captain says the letter name. 10. Teacher moves the text box off of the square. If the same answer appears on the “Match Side,” the first team has won 1000 points and the teacher moves the blue text box with “1000 pts” to the left side on top of the red text box from the “Select” column. Play then goes to the second team. 11. If a different answer appears under the “Match” square, the teacher will recover both squares with their respective text boxes and play goes to the second team. The second team may select any letter under the “Select” column except the one just played by the previous team. 12. Play continues until a match has been made for every question. 13. Team with higher number of points wins. 14. No player may have notes or definitions in view. 15. No player may take notes of the terms as they are revealed.

And now, there is often more than one CPU inside a computer. Still, the look and function of these components don’t really differ that much from the personal computers years ago. But Bill Gates recently said, “You haven’t seen anything yet.” How will computers look and function in the coming years? There are promises of big changes. Assignment: 1. Working in a group and using the internet, research new developments in computers. To get started, use a search engine (such as Google or Yahoo) and search for “Computer Future,” “New Developments for Computers,” etc. Think of new words or phrases to get a variety of responses. 2. Find at least one big change in the way computers will look or function (you may use more than one change). 3. Answer the following questions: A. B. C. D. Where did you find the information? What is the change? Which of “today’s” components will change and how? What does the change mean to those who use computers? 4. Be prepared to present your findings to the class.
