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. An action - such as the CTRL-ALT-DELETE key combination or the insertion of a smart card - that clears memory of certain types of viruses before a user logs on.






2. Erasable programmable read-only memory. A ROM chip that is erasable and reprogrammable through the use of specialized software.






3. Aka routing information protocol.






4. A network connection device that routes IP packets between networks.






5. In reference to the Windows operating systems - one that can utilize up to 4 GB of address space.






6. The top-level folder or directory in the file structure. This appears the same - regardless of the underlying file system.






7. The proportion between an image's width and height. Traditional CRT monitors have an aspect ratio of 4:3. Widescreen displays have an aspect ratio of 16:9.






8. The process that authenticates a user and verifies the user account's level of access to a resource.






9. A Windows server running the WINS service to maintain and resolve NetBIOS names.






10. A type of printer that uses a film coated with colored wax that melts onto paper. These printers are similar to dye-sublimation printers but differ in two major ways: the film contains wax rather than dye - and these printers do not require special p






11. Aka Integrated Drive Electronics.






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






13. An internal bus in a CPU that connects it to memory and video.






14. Aka channel service unit.






15. An Advanced Options menu choice that simply causes Windows to restart normally (if it can).






16. A T-1 multiplexer or a special LAN bridge that connects to the telephone company's channel service unit (CSU) - which encodes data for transmission over a T-carrier circuit.






17. The second version of the IEEE 1394 standard; it supports speeds up to 3.2 Gbps and distances of up to 100 meters.






18. Aka DDR3 SDRAM.






19. Fiber-optic cable in which multiple light waves can pass simultaneously. Usually larger in diameter than single-mode fiber; and each wave uses a certain portion of the fiber cable for transmission.






20. The protocol used to allow client computers to pick up e-mail from mail servers. The current version is POP3.






21. Digital versatile disc (DVD) discs that can be rewritten to - and data can also be overwritten. This standard is newer than DVD-RW. This term also refers to the drives that can write to these discs.






22. Two disk drives used for RAID 1 - in which data is written to both drives at the same time - a practice called mirroring.






23. A file system in which one of the basic structures is a table used for allocating space. This table is called the file allocation table (FAT).






24. A measurement of a body part - such as a fingerprint or retina scan.






25. A type of switched network used by phone companies.






26. A 3/32-inch audio connector.






27. An arrangement of pins on a processor in which the pins are offset in a way that allows for a higher pin density than PGA.






28. In a CPU - special memory that resides outside the CPU's core and is used to temporarily store instructions and data in order to increase the processing speed. Also called Level 2 (L2) cache and Level 3 (L3) cache - depending on the design of the CPU






29. 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






30. Both the connectors on the RDRAM memory modules and the motherboard sockets (or slots) that match them.






31. The moving of data from one storage device to another.






32. A KVM switch that uses software and special keyboard commands to switch among controlled computers. Also called anactive KVM switch.






33. A Windows sleep mode that uses hard drive space to save all the programs and data that are in memory at the time you choose this mode. The computer then completely shuts down and requires no power while it is hibernating.






34. Fiber-optic cable that allows only a single light wave to pass down the cable.






35. Aka Advanced Configuration and Power Interface.






36. A practice begun in Windows 2000 in which all of the operating system code is digitally signed to show that it has not been tampered with.






37. Radio frequency interference. Radio signals that occur in proximity to equipment that is sensitive to these types of signals.






38. A TPM is a special microchip - installed on a motherboard - that stores passwords - keys - and digital certificates. Various services - such as BitLocker can store such security data in this chip.






39. A menu that opens from the Start button on the taskbar.






40. An enhanced version of PPP - which adds the ability to secure the point-to-point connection with encryption.






41. Aka uninterruptible power supply.






42. Aka low-voltage differential.






43. Aka security auditing.






44. Aka Internet service provider.






45. The practice of forcing a CPU or other computer component to run at a higher clock rate than the manufacturer intended.






46. A parallel port mode in which the signals can be transmitted in both directions between the PC and parallel devices connected to the computer.






47. A technology for LCD displays in which transistors are positioned at each pixel.






48. In fiber-optics - a single light wave passing down a cable.






49. A protocol developed in the 1980s by IBM for managing names on a network. Also used by Microsoft in early networking. Replaced by DNS on TCP/IP networks.






50. A small cassette containing an ink reservoir used to provide the medium for certain printers. An ink cartridge will only fit a certain model printer.
