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. A modified version of FAT12 and FAT16 used in Windows since Windows 95.






2. Aka external cache.






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






4. A device - usually resembling a power strip - that protects equipment from power surges.






5. The type of connector used in the ExpressCard interface.






6. Aka PCIe.






7. 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.






8. A process that runs "behind the scenes" with a low priority - does not require input - and rarely creates output.






9. A mark on a building created by a war driver to specify where a hotspot exists. People "in the know" look for these marks to identify hotspots for their use.






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






11. A DVD drive that cannot write to but can read DVD discs.






12. The signal in a television transmission that contains the color of the image.






13. The medium for a laser printer - which is normally packaged within a toner cartridge.






14. Also called mirroring - this RAID array type provides fault tolerance because all the data is written identically to the two drives in the mirrored set.






15. An area of the Windows taskbar used by programs and some hardware devices to display status icons. Also called thenotification area or system tray.






16. A subprotocol of TCP/IP used for connectionless communications in which each packet is sent without establishing a connection.






17. Digital versatile disc (DVD) discs that can be written to - but data cannot be overwritten. This standard is newer than DVD-R. This term also refers to the drives that can write to these discs.






18. Any type of computer that you can easily transport and that contains an all-in-one component layout.






19. An organization that creates specifications for infrared wireless communication.






20. The type of battery used in the first portable PCs - which was heavy and inefficient.






21. A virtual tunnel created between two endpoints over an untrusted network. The tunnel is created by encapsulating the packets within special packets for the tunnel. Other security methods are also usually applied to a VPN - such as encrypting the data






22. The amount of data that can travel over a network at a given time.






23. Aka double-data rate (DDR) SDRAM.






24. Aka virtual circuit.






25. One of the two main protocols of the TCP/IP protocol suite - TCP breaks the data into chunks - called datagrams. Each datagram also contains information - stored in a header - which is used by the TCP protocol on the receiving end to reassemble the c






26. A 4-pin connector that - in addition to a 20-pin connector - is part of motherboard power connector that follows the ATX 12V standard.






27. 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.






28. A common connector used to connect a power supply to internal peripherals.






29. An external serial bus standardized by the IEEE. Apple first developed it as FireWire. Other manufacturers call it i.link or Lynx. It can support up to 63 daisy-chained devices. Since the introduction of the faster update - IEEE 1394b - the original






30. The role of the first EIDE drive on a PATA channel.






31. Aka permanent virtual circuit.






32. In reference to IDE PATA drives - the master drive on the first channel.






33. Unsolicited e-mail.






34. A remote KVM switch that uses either Cat 5 or USB cabling. The distance it can be from the computers it controls is a function of the length limits of the cabling; it normally uses a proprietary protocol and special hardware.






35. Aka IEEE 1394.






36. Aka dynamic RAM.






37. An LCD display that accepts a digital signal. Early LCD displays accepted an analog signal and converted it to digital internally.






38. An operating system that runs on a network server and provides file sharing and access to other resources - account management - authentication - and authorization services.






39. Aka Media Access Control (MAC) address.






40. The digital versatile disc (DVD) encoding format used for data storage.






41. The high-definition optical disc formatting standard - promoted by Toshiba - that was defeated by the Blu-ray Disc standard as the widely accepted high-definition standard.






42. Aka pin grid array.






43. A measurement of the volume of electrons - also called current. It is calculated with the formula amps = watts / volts.






44. A shared folder on a distribution server containing the source files for a remote installation.






45. A standard for interconnecting electronic musical instruments to communicate with computers and among themselves.






46. Aka DDR2 SDRAM.






47. An Advanced Options menu choice that creates a log of the Windows startup in a file named NTBTLOG.TXT and saved in thesystemroot folder (normally C:Windows).






48. A cable medium that transmits light pulses rather than electrical signals - so it is not susceptible to electromagnetic interference (EMI).






49. A perpetrator of malicious software attacks against computers and networks. Also called a cracker.






50. Aka complementary metal-oxide semiconductor.
