- 23. The most important part of any modern computer system; it controls the other parts of the computer.
- 24. The top-level folder, or directory, of a file system.
- 25. A printer that uses electrical charges and heat to fuse tiny plastic particles (called toner) to the paper.
- 27. An advanced system of cooling in which liquid coolant is in direct contact with the CPU. It offers a high level of heat transfer that quickly reduces the temperature of the CPU's surface.
- 28. An additional computer processor that provides graphics processing. It improves performance by relieving the CPU of this duty.
- 30. 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.
- 31. An industry professional who oversees the design and development of computer devices and other systems that use electricity and electronics.
- 33. A communication technology that uses light waves to transmit information through the air.
- 34. The use of user and file attributes that control which users can read, write, move, or delete each file.
- 37. 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.
- 41. The most common type of long-term storage that uses thick magnetic disks encased in a protective housing to store data.
- 42. An interface used to connect peripherals such as digital cameras and external hard drives to a computer. It is no longer commonly used.
- 44. A process that combines knowledge, experience, and intuition to quickly identify the cause of a problem.
- 45. A technician who repairs both software and hardware issues including but not limited to installing, troubleshooting, servicing, and repairing devices, as well as network equipment such as routers, switches, cables, and related network hardware.
- 46. A connector, typically white with three rows of eight pins, designed to connect digital monitors to a computer.
- 48. A connector now available on a wide variety of devices such as computers, monitors, TVs, Blu-Ray players, and more. HDMI is used to transfer high-definition signals. It supports both audio and video data.
- 49. A common interface used to connect peripherals, such as mice, keyboards, printers, and digital cameras to a computer.
- 50. A display device that allows a user to interact with a computer by touching, tapping, and swiping areas on the screen.
Down
- 1. 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.
- 2. A compact, portable storage device that uses special memory chips to store data.
- 3. When parts of a single file, program, or application are stored in different areas of a physical disk.
- 5. A circuit board that connects to a computer's motherboard, giving it additional power or functionality.
- 11. A short-range wireless communication technology used to connect peripherals such as wireless headphones, speakers, keyboards, mice, smart watches, printers, and game controllers to a computer, including smartphones.
- 13. Small computing devices such as tablets and smart phones that are much more portable than desktops and laptops.
- 14. supply A unit that supplies electricity to the motherboard and other computer components.
- 16. A storage device that uses light instead of magnetism to store information. This include CD-ROM, DVD, and Blu-ray devices.
- 17. A liquid-cooled system that places a water-cooled heat exchanger near a heat source. The exchanger removes the heat, reducing the air temperature.
- 19. The process of converting information so it cannot be understood without decrypting it using a key, especially to prevent unauthorized access.
- 21. The communication system that allows data to be transferred between the components inside a computer. The term bus comes from the Latin word omnibus that means for all.
- 22. A device that scans paper documents and converts them into digital files.
- 26. 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. A file is the smallest container that can be copied, deleted, or moved within a file system.
- 29. The methods and structures that an operating system uses to organize files on a storage device like a hard drive. File systems often use directory structures to keep track of files.
- 32. A computer component that attaches to a chip (such as a CPU) that disperses heat and prevents overheating.
- 35. An event in which two objects with different charge levels come together resulting in an electrostatic shock.
