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 portion of system memory used by a video adapter built into a motherboard.






2. A variety of persuasion techniques used for many purposes






3. A video signaling method in which analog video information is transmitted as two or more discrete signals. Two general types of component video are RGB Video and S-Video.






4. Aka hacker.






5. Aka secure socket layer.






6. A device found in laptops that monitors and regulates power usage. The features vary by manufacturer - but typically - they provide short-circuit protection - give "low battery" warnings - and can be configured to shut down the computer automatically






7. A version of the FAT file system used by hard drives and some flash drives (thumb drives - etc.) - using a 32-bit file allocation table.






8. A Windows command prompt utility that uses the WFP (Windows 2000 and Windows XP) or WRP (Windows Vista and Windows 7) service to scan and verify the versions of all protected system files after you restart your computer.






9. A RAM standard that replaces the original DDR2 standard and requires far less power - while providing almost twice the bandwidth. A stick of DDR3 SDRAM has 240 pins - but is keyed so it will not fit into a socket designed for DDR2. DDR3 SO-DIMMs have






10. Dual inline package. A very tiny slide that indicates two states. Motherboard and other circuit cards often have one or more groupings of DIP switches for configuring options.






11. A memory module (stick) that installs into matching DIMM sockets found on many motherboards. The word "dual" refers to the separate pins or connections on both sides of the module and socket.






12. Introduced in 1993 - the most common expansion bus architecture in PCs in the mid 1990s. It transfers data in parallel over a data bus that is either 32- or 64-bits wide.






13. In the laser printing process - the step in which the toner on the drum is transferred to the paper.






14. The amount of time it takes a packet to travel from one point to another.






15. A group of networking standards created by the IEEE 802.3 subcommittee.






16. A method for supporting up to 8.3 GB capacity hard drives. Both the BIOS and hard drive system must use LBA.






17. Aka digitizing tablet.






18. An LCD display setting that adjusts the viewable area of the display vertically.






19. Local area networking using radio waves - with the most common based on the IEEE 802.11 group of standards (802.11a - 802.11b - 802.11g - and 802.11n).






20. A device required at both ends of a T-carrier system connection.






21. A technology that makes 802.11n speeds possible - using multiple antennas to send and receive digital data in simultaneous radio streams that increases performance.






22. A remote KVM switch that captures the keyboard - video - and mouse signals - encodes them into IP packets - and sends them over an IP network.






23. A new level of an operating system with major changes to the core components.






24. A type of KVM switch that is controlled through a mechanical switch on the box.






25. In networking - the authorization to access a computer or resource on a computer. Specific permission levels include read - change - modify - etc.






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






27. In computer networking - a network located between a private network and the Internet with a firewall on both sides. A DMZ contains servers offering services to users on the Internet and inside the protected private network.






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






29. A cooling fan mounted directly on the case - as opposed to a power supply fan - which is inside the power supply.






30. The third version of the IEEE 1394 standard; it is a departure from the old standards in that it uses Category 5e twisted pair cable with RJ-45 connectors - combining Ethernet and FireWire.






31. Aka Automatic Private IP Address.






32. A Windows service designed to allow a user to invite someone to help troubleshoot a problem.






33. A card that fits into the PC Card interface - including both PC Card and CardBus cards. This type measures 85.6 millimeters long by 54 millimeters wide and measures 10.5 mm thick.






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






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






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






37. Aka virtual file allocation table.






38. Digital versatile disc (DVD) discs that can be written to once - but data cannot be overwritten. This term also refers to the drives that can write to these discs.






39. The Windows Vista and Windows 7 tool for gathering and viewing performance data involving memory - disks - processors - network - and other objectives.






40. A digital video interface that has several modes - including one that offers downward compatibility with analog displays. It requires a special connector - which comes in several variations to support the DVI modes.






41. The fine copper lines that are the electronic circuits through which power - data - and control signals travel on a circuit board.






42. The format in which IP addresses are usually shown - with decimal numbers separated by "dots" as in 192.168.100.2.






43. On a motherboard - the type and location of components - as well as the size of the board itself.






44. A rectangular connector with a locking clip on one side and a number designation that refers to the size rather than the number of wires.






45. Aka Hypertext Markup Language (HTML).






46. A wireless network standard that uses the 2.4 GHz band at a speed of up to 54 Mbps. It is downward-compatible with 802.11b.






47. A device used to scan smart cards.






48. Memory that can only be read and that contains program code. ROM is also called firmware.






49. In Windows - an Advanced Options menu choice that will start Windows without the Windows GUI (EXPLORER.EXE) and with only a simple Command Prompt window from which you can launch Windows administrative utilities.
