Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The moving of data from one storage device to another.






2. A simple type of component video signal that sends three separate signals






3. A heat dissipation device - usually a passive metal object with a flat surface attached to a component - such as a chip.






4. A standard used in laptops that is based on PCI. The biggest difference is that Mini PCI is much smaller than PCI






5. The traditional transmission system for television video signals - which combines the color and brightness information with the synchronization data into one signal. The TV circuitry then separates the two signals from the composite signal.






6. The box that houses the main computer system.






7. A metal strip used to cover an empty slot in order to preserve the correct air flow and keep dust out.






8. A printer that creates printed output line by line.






9. An LCD display using an old technology that has a grid of horizontal and vertical wires with a transistor at the end of each wire. When two transistors (one at the x-axis and one at the y-axis) send voltage along their wires - the pixel at the inters






10. A technology for transferring serial data at high speeds. Also known as low-voltage differential signaling (LVDS).






11. A CPU containing four CPU cores.






12. Aka systray.






13. A local bus designed for video only - it provides a direct link between the processor and the video card - giving the video card direct access to main memory.






14. The code used to provide multiple language support to Windows.






15. An adapter used to connect a computer or other device to a network medium.






16. Aka central processing unit.






17. A unit of measurement of actual delivered power - calculated by the formula watts = volts






18. An area under the pinned items list on the Windows XP Start menu that contains shortcuts to recently run programs.






19. Aka Wireless Fidelity.






20. The wireless nodes (including the WAP) communicating together in infrastructure mode.






21. An early technology for increasing the performance of DRAM.






22. A network protocol suite originally developed for the Internet; it has been mostly adopted on private networks.






23. Aka emergency repair disk.






24. In a laptop - a compartment that holds a single media device that is switchable with another.






25. A network in which all of the computers essentially operate as both servers (providing access to shared resources) and clients (accessing those shared resources).






26. Showing consideration for others.






27. A program file or some special data file that is part of the operating system and is very important to proper operation of the OS.






28. An organization that creates standards for laptop computer peripheral devices.






29. A technology used by hard drives to speed up data transfers by using DMA channels.






30. A firewall consisting of software that you can install on any computer - as opposed to the software built into a hardware firewall. Also called personal firewalls because they are designed to be installed on individual desktop computers.






31. Aka Simple Mail Transfer Protocol.






32. A laptop in which the display is an integrated digitizer.






33. The use of words - often technical and uncommon - that both parties understand in the same way.






34. Aka digital video interface.






35. The worldwide network that carries traditional voice traffic.






36. The filename for the System Configuration Utility - which allows you to test various scenarios for Windows startup for troubleshooting purposes.






37. Aka continuity RIMM.






38. A type of DSL service in which the download speed is higher than the upload speed.






39. Aka PCIe.






40. A magnetic mass storage device primarily used for backing up data from computers.






41. A special-purpose computer designed for a certain task and installed within a device.






42. A portion of a computer's chipset that controls communications between the CPU and such I/O busses as USB - IDE - PS2 - SATA - and others.






43. A wireless mode requiring a wireless access point (WAP).






44. Aka Windows Internet Naming Service.






45. A data encryption technology used for securing data transmitted over the Internet.






46. The original version of the IEEE 1394 standard that supports speeds up to 400 Mbps.






47. An assigned channel over which a device can send a signal to the processor to get its attention.






48. The primary control device for a computer system. The CPU is simply a chip containing a set of components that manages all the activities. Also called a processor.






49. A communications network made up of personal computing devices - such as computers - telephones - and personal digital assistants.






50. A DVI mode that supports digital video signals and is partially compatible with HDMI. Aka also digital video interface and High-Definition Multimedia Interface.
