Comptia A + Certification

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






2. Aka Dynamic Host Configuration Protocol.






3. Wide-ultra-extended graphics array






4. 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.






5. 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.






6. In an operating system GUI - a tiny graphic representing an application - folder - disk - menu item - or other entity.






7. Aka fast page mode.






8. A drive interface for EIDE drives that transfers data serially at speeds between 150 MBps and 300 MBps and 6 Gbps - depending on the version of the standard.






9. A feature of HDMI that prevents people from illegally copying HD DVDs. Aka also High-Definition Multimedia Interface (HDMI).






10. An underlying protocol that supports Microsoft Remote Desktop.






11. Authentication is validation of a user account and password that occurs before the security components of Windows will give the user access to the computer.






12. Aka floppy disk drive.






13. A wireless network standard that uses the 5 GHz band.






14. Local area networking using radio waves that includes several implementations based on the IEEE 802.11 group of standards.






15. Aka Serial Attached SCSI.






16. Unsolicited messages sent over an instant messaging service - such as Windows Messenger.






17. Aka High-Definition Multimedia Interface.






18. A pointing device - often built into a laptop - which is a smooth rectangular panel over which you move your finger to move the pointer on the display.






19. 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.






20. A WAN connection that uses an analog modem rather than a network card and uses standard phone cables rather than network cables.






21. A plug designed for testing a specific port type (e.g. - serial - parallel - or USB). The plug does not connect to a cable but reroutes the sending pins to the receiving pins. Using special software on the computer - a loopback test is performed in w






22. Aka RAID 5.






23. Specialized hardware used to create and manage a RAID array.






24. The component that provides power for all components on the motherboard and internal to the PC case. Also called a power supply unit (PSU).






25. A communication service provided over a telecommunications network or computer network. A VC logically resembles a circuit while passing over a complex routed or switched network - such as the phone company's frame relay network.






26. A multi-GPU solution developed by NVIDIA.






27. Data communications over the cellular telecommunications networks.






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






29. Aka Enhanced IDE.






30. An early international standard for sending voice and data over digital telephone wires. ISDN uses existing telephone circuits or higher-speed conditioned lines to get speeds of either 64 Kbps or 128 Kbps. ISDN lines also have the ability to carry vo






31. Aka Advanced Technology Attachment.






32. A method of memory error-checking that is more sophisticated than parity checking. Like parity checking - it adds an extra bit per byte. In addition - software in the system memory controller uses an algorithm to both detect and correct errors.






33. A riser card standard that AMD - 3Com - and others introduced in 2000 to supersede AMR. It uses one PCI slot - provides accelerated audio and modem functions as well as networking - and supports multiple Ethernet NICs.






34. Laser discs sold at retail stores that contain music (audio CDs) or software (data CDs).






35. The BIOS configuration settings - also called system settings - accessed via a special BIOS-based menu during system startup.






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






37. The role of the second EIDE drive on a PATA channel.






38. A small expansion card introduced in the late 1990s that plugs into a special slot on a motherboard and uses the CPU to perform modem functions and sound functions. It is not plug and play compatible.






39. Digital versatile disc (DVD) discs that can be written to - and data can also be overwritten. This term also refers to the drives that can write to these discs.






40. A term applied to a CPU - motherboard - or other components that conform to the newer 64-bit architecture. Also referred to as 64-bit.






41. Aka optical character recognition.






42. A program that causes a modem to dial phone numbers surreptitiously.






43. A solid-state storage standard for high-capacity (2 - 4 - and 8 GB) memory cards that are tiny






44. 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).






45. The hardware architecture - including the CPU - BIOS - and chipset.






46. Used to represent the luminance signal in S-Video.






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






48. The worldwide network that carries traditional voice traffic.






49. 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.






50. A generic reference to a PC's serial communications port - in which the x represents the port number.
