- 3. Records sound
- 5. The dissipation of large amounts of heat, which is created while a computer system is running. Heat is generated inside the computer tower by various hardware such as CPU, video card or even the hard drive.
- 7. Fans They cool the surrounding area by circulating fresh air through the case by drawing out hot air, drawing in cooler air, or both.
- 9. drive Storage device added to the computer by using a USB port.
- 11. fans Used in conjunction with heat sinks to prevent overheating of the components in central processing units.
- 13. One of the most essential parts of a computer system. It holds together many of the crucial components of a computer, including the central processing unit (CPU), memory and connectors for input and output devices.
- 14. tools, machinery, and other durable equipment.
- 15. code Groupings of 1's and 0's that makes information that a computer can understand.

- 4. Supply A hardware component that supplies power to an electrical device. It receives power from an electrical outlet and converts the current from AC (alternating current) to DC (direct current), which is what the computer requires.
- 6. Card Connects to the motherboard of a computer system and generates output images to display. Also referred to as graphics cards. They include a processing unit, memory, a cooling mechanism and connections to a display device.
- 8. Drive Fans Often used in systems with heat-production challenges from a lot of hard drive usage.
- 10. translates source code into machine code one line at a time
- 12. The logic circuitry that responds to and processes the basic instructions that drive a computer. Has generally replaced the term central processing unit (CPU).
- 19. This is the same RAM. It is volatile memory that stores information on an integrated circuit used by the operating system, software, and hardware. When power is turned off it will erase the contents it has gathered. You can add it in the PCI slots on the motherboard.\
- 21. Drive A type of computer disk drive that reads and writes data from disks through laser beaming technology. This type of drive allows a user to retrieve, edit and delete the content from disks such as CDs, DVDs and Blu-ray disks.
