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. Aka communication network riser.






2. A CPU containing four CPU cores.






3. A protocol used by e-mail clients for communicating with e-mail servers. This protocol is replacing the POP protocol. IMAP allows users to connect to e-mail servers and not only retrieve e-mail - which removes the messages from the server - as they c






4. One or more chips in a computer's chipset that controls communications between the CPU and RAM on the motherboard.






5. A protocol used to resolve an IP address to a MAC address.






6. A type of power supply that converts AC power to voltages needed for a device. AC adapters are generally used for portable PC systems and other devices.






7. Aka complementary metal-oxide semiconductor.






8. The act of discovering the cause of a problem and correcting it.






9. A type of thermal printer in which a heated print head burns dots into the surface of heat-sensitive paper.






10. A multi-GPU solution developed by NVIDIA.






11. A special disk used for recovering an OS failure in Windows 2000. It requires that you create the ERD while the system is healthy - and then use it - along with the Windows Setup CD - to repair Windows.






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






13. A computer's temporary working space - usually in DRAM chips.






14. Aka Digital Light Processing.






15. Aka power-on self-test.






16. 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.






17. DRAM that runs at the speed of the system bus (up to 100-133 MHz).






18. The circuit board in a computer to which all other components directly or indirectly connect. Also called a mainboard - system board - mobo - or planar board.






19. Aka External Serial ATA.






20. Aka microcode.






21. Memory chips that use a special Rambus channel that has a data transfer rate of 800 MHz. A double channel width results in a 1.6 GHz data transfer. RDRAM sticks use special RIMM slots.






22. In reference to a memory module - how much information the processor can access from or write to memory in a single cycle.






23. A file operation in which the file or folder remains in the source location - and a duplicate is created in the target (destination) location.






24. Audio connectors that use a 1/8" single pin plug.






25. The information transfer protocol of the World Wide Web (WWW). Included in HTTP are the commands Web browsers use to request Web pages from Web servers and then display them on the screen of the local computer.






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






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






28. The oldest of the Wi-Fi encryption standards. It uses 64- or 128-bit encryption that is easily broken. It does not encrypt the actual data in a packet - and it does not perform user authentication on a packet.






29. A device that converts digital signals from the broadband connection to voice for the analog phone and the analog voice signals to digital signals for the digital network.






30. Super XGA - a video graphics mode with a maximum resolution of 1280






31. Aka alternating current.






32. Aka external cache.






33. Pertaining to a DVD drive or disc that can store data in a single layer of pits on each data side.






34. Using the same cabling as 10BaseT - Fast Ethernet - or 100Base-T - operates at 100 Mbps and uses different network interface cards.






35. Aka Domain Name Service.






36. The sudden and uncontrolled movement of electricity from an object with a greater charge to one with a lesser charge. Also called static electricity.






37. A virus that is self-replicating.






38. A tool for migrating user data and settings from one Windows computer to a computer running Windows XP.






39. Aka DDR3 SDRAM.






40. A video mode that most often consists of a combination of 640






41. Aka demilitarized zone.






42. 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.






43. Memory that does not require power to keep stored data intact. Also called flash memory.






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






45. Aka Advanced Micro Devices.






46. A power supply that converts between alternating current and direct current.






47. A process applied to digitally signed code to unencrypt the signature data and use the information to verify the program code was not modified since the signature was added.






48. A very old expansion bus standard - seen in the early IBM PC.






49. Aka capture card.






50. A connector used to attach coaxial cables to computers and network equipment. Origin of the term may be "Bayonet-Neill-Concelman" or "British Naval Connector."
