- 20. A cooling system composed of a liquid heat sink, internal liquid pump, a fan, and a radiator that all actively pump cooled liquid in and out with no help from an outside pumping system.
- 22. The top-level folder, or directory, of a file system.
- 24. A camera component that focuses the light that enters it into a point. Behind the point, the light spreads out again, eventually creating an upside-down image of the light that entered.
- 26. When parts of a single file, program, or application are stored in different areas of a physical disk.
- 31. A process that combines knowledge, experience, and intuition to quickly identify the cause of a problem.
- 33. A compact, portable storage device that uses special memory chips to store data.
- 35. A circuit board that connects to a computer's motherboard, giving it additional power or functionality.
- 37. A utility in which all fragmented files on a drive are found and reconsolidated into the same physical location on the disk.
- 41. An audible alarm that occurs when a computer encounters an issue before a power-on self test (POST) has completed when booting. The number and frequency of the beeps can be used to compare information found in the motherboard manual and identify the issue.
- 43. A common method of cooling that uses fans to move hot air out of a system.
- 44. Heat sinks and fans that keep computer components, especially the CPU, from overheating.
- 46. A connector, identified by its blue color and three rows of pins, that is used to connect older monitors to a computer.
- 47. A three step cycle (fetch, decode, and execute) that processors use to execute instructions.
- 51. A connector used to connect a computer to an HDMI monitor or TV.
- 52. A common interface used to connect peripherals, such as mice, keyboards, printers, and digital cameras to a computer.
- 53. A device, usually external to a computer, that is plugged into a computer's communication port or is connected wirelessly. Common peripherals are keyboards, mice, monitors, speakers, and printers.
- 56. A memory issue in which unintentional changes have been introduced to your original files resulting in missing files or data, scrambled documents, crashing programs, spontaneous reboots, registry errors, and missing systems.
Down
- 2. An HDD that can be connected as a peripheral to a computer.
- 3. A connector, typically white with three rows of eight pins, designed to connect digital monitors to a computer.
- 4. A storage device that uses light instead of magnetism to store information. This include CD-ROM, DVD, and Blu-ray devices.
- 6. A computer component that attaches to a chip (like a CPU) that disperses heat and prevents overheating.
- 7. An event in which two objects with different charge levels come together resulting in an electrostatic shock.
- 9. A device with similar capacity to an HDD that uses flash storage instead of magnetic disks to store data. SSDs are much faster and more durable than hard disk drives but usually are more expensive.
- 11. A camera component that sits between the lens and the sensor, allowing light to enter for a short time.
- 12. Small computing devices that are much more portable than desktops and laptops.
- 14. The process of dividing a single physical disk into multiple logical drives called volumes.
- 17. A connector used to connect a computer to a wired network.
- 21. A liquid-cooled system that places a water-cooled heat exchanger near a heat source. The exchanger then removes the heat, reducing the air temperature.
- 23. An advanced system of cooling where liquid coolant is in direct contact with the CPU offering a high heat transfer that quickly reduces the temperature of the CPU's surface.
- 25. A small computer that combines a display and keyboard and is designed to be easily carried.
- 27. A unit that supplies electricity to the motherboard and other computer components.
- 28. A communication technology that uses light waves to transmit information through the air.
- 29. An uncommon interface used to connect peripherals such as digital cameras and external hard drives to a computer.
- 30. The process of tracking changes to a file so that a file can be repaired or restored in case of file corruption or data loss.
- 32. A printer that uses electrical charges and heat to fuse tiny plastic particles (called toner) to the paper.
- 33. The smallest container within a computer's storage system that is used to store information such as data, settings, and commands used in a computer program.
- 34. A device that can be connected to a computer or network that scans paper documents and converts them into digital files.
- 36. A component, sometimes built into and sometimes plugged into the motherboard, that provides network connectivity.
- 38. System The methods and structures that an operating system uses to organize files on a storage device like a hard drive.
- 39. A family of processors most often used in smartphones due to its lower power requirements. This is accomplished by reducing the processors' instruction set.
- 40. A light sensitive surface used to capture the image focused by the lens.
- 42. Format The way a file is organized. File formats are indicated by an extension such as .jpg, .gif, .png., .mp3, .wav, .wma, .mp4, .avi, and .wmv.
- 45. An additional computer processor that provides graphics processing, providing better performance by relieving the CPU of this duty.
- 48. A large, flat computer component that connects the important components of the computer, such as the CPU, RAM, and the BIOS chip. It also has power and other communications connections.
- 49. The process of converting information so it cannot be understood without decrypting it using a key, especially to prevent unauthorized access.
- 50. Reencoding a file to consume less storage space.
- 54. The most important part of any modern computer system that controls the other parts of the computer.
