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 password that locks your hard drive and is often stored in a TPM chip.






2. Aka World Wide Web.






3. Aka Sony/Philips Digital Interface.






4. 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






5. Software that takes a scanned image and interprets the patterns in the image into alphanumeric characters.






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






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






8. 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.






9. The location where a cable attaches to a computer. Alternatively - a connector on a motherboard for memory - CPUs - power - or other circuitry.






10. 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






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






12. In a laser printer - a metal drum with an electro-photosensitive coating to which a charge can be applied by a laser beam.






13. Program code that allows an operating system to control the use of a physical device.






14. 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.






15. Aka antistatic mat.






16. A CRT video setting - also known as the vertical refresh rate - that controls the rate per second at which an image appears on the tube.






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






18. Software created to perform malicious acts. Also called malicious software.






19. Aka arithmetic logic unit.






20. A term used for CPU packaging that indicates that a chip has columns and rows of pins.






21. An input device that uses a stylus. Available as an external device - it uses touch screen technology and is usually at least the size of a sheet of paper. Also called a digitizer.






22. An exact duplicate of an entire hard drive's contents - including the OS and all installed software.






23. The file system component in the FAT file system in which the OS creates a table that serves as a map of where files reside on disk. Also called the FAT table.






24. Aka motherboard.






25. A network connection over long distances - traditionally using phone lines or satellite communications.






26. Aka paging file.






27. A common connector used to connect a power supply to floppy drives.






28. Aka second-level domain.






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






30. The disruption of signal transmission caused by the radiation of electrical and magnetic fields. Electric motors are a common source of EMI.






31. Aka low-voltage differential signaling (LVDS).






32. A variation of the PGA CPU packaging that was used with Pentium CPUs.






33. A DVI mode that supports downward compatibility with analog displays.






34. Aka Automatic Private IP Address.






35. A magnetic storage device that contains a thin internal plastic disk - capable of receiving magnetic charges contained in the thin magnetic coating on the disk.






36. Aka dynamic RAM.






37. A pen-sized tool that has a plunger at one end. When pressed - the plunger causes small - hooked prongs to extend from the other end of the tool for retrieving dropped objects from inside a computer.






38. A dedicated computer that stores data and provides print services or other capabilities to network clients.






39. Data storage technology with no moving mechanical parts that uses large-capacity - nonvolatile memory - commonly calledflash memory or solid-state drives.






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






41. In a Wi-Fi network - the networking mode that allows peer-to-peer communications without the use of a centralized wireless hub - called a wireless access point (WAP).






42. A raised area on an optical disc that is alternated with depressed areas to be interpreted as data.






43. A setting on an LCD display that adjusts the viewable area of the display horizontally.






44. Software instructions stored in ROM chips. It exists on most PC components and on the motherboard.






45. A mode for parallel ports that allows access to special features in the PC called DMA channels. This mode is approximately ten times faster than regular bidirectional mode and is designed for printers and scanners.






46. Aka paging file.






47. A technology for transferring serial data at high speeds. Also known as low-voltage differential signaling (LVDS).






48. Aka distributed denial of service attack.






49. 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.






50. In a CPU - special memory that resides within the CPU's core and is used to temporarily store instructions and data in order to increase the processing speed. Also called L1 cache.
