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






2. An assigned channel over which a device can send a signal to the processor to get its attention.






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






4. A connector that is slightly larger than an RJ-11 connector and contains eight wires. RJ-45 connectors most commonly attach twisted-pair cables to Ethernet network cards.






5. In the laser printing process - a wire that passes a small positive charge to paper as it travels through the printer. This positive charge attracts the negatively charged toner particles on the drum to the paper.






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






7. In Windows - an Advanced Option that is only available in Windows Servers in the role of domain controllers - although it appears on the menu in non-domain controllers.






8. A device that sits at the connection between networks and routes packets based on their logical destination addresses.






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






10. A device installed at the end of a SCSI chain to absorb signals so they do not bounce back along the cable.






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






12. This attack occurs when a massive number (up to hundreds of thousands) of computers send DoS attacks to a server - making it unavailable.






13. 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.






14. In Disk Management - the status given to a dynamic disk that has not had its configuration information (stored on the disk) imported into Windows. This status occurs when a dynamic disk is moved to a different Windows computer or when a dynamic disk






15. Aka pointing stick.






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






17. An encryption technology introduced in Windows Vista Enterprise and Ultimate editions - Windows Server 2008 - and also in Windows 7 Ultimate and Enterprise editions. It encrypts the entire boot volume.






18. Aka routing information protocol.






19. A device that uses a measurement of a body part - such as a fingerprint or retina scan.






20. 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.






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






22. A connection point on a device or computer - sometimes called a socket.






23. A tool for testing if a cable can connect properly end-to-end and to determine if a cable has a short. These tools are available for a variety of cable types.






24. A T-1 multiplexer or a special LAN bridge that connects to the telephone company's channel service unit (CSU) - which encodes data for transmission over a T-carrier circuit.






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






26. An organization that creates standards for laptop computer peripheral devices.






27. A measurement of the pressure of electrons - the electromotive force. It is calculated by the formula volts = watts / amps.






28. A socket for a PGA CPU that has a retention lever as well as contacts to match the number of pins on the CPU. The lever is used to attach the CPU to the socket in a manner that does not require force to insert or to remove the CPU.






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






30. Aka lit pixel.






31. Aka low-voltage differential (LVD).






32. Memory chips that provide much slower access than SRAM chips but that can store several megabytes of data on a single chip (or hundreds of megabytes - or even gigabytes - when they are packaged together on a "stick").






33. The first physical sector on a floppy disk or the first sector on a hard drive partition. The boot record contains information about the OS. The boot record on a primary active partition is used to start the operating system. Also called the boot sec






34. In the laser printing process - the stage in which the printer's high-voltage power supply (HVPS) conducts electricity to the primary corona wire so it can pass the voltage on to the printer's electro-photosensitive drum.






35. In reference to the Windows operating systems - one that can utilize more than 4 GB of address space. Depending on the version - 64-bit Windows can address a maximum of from 8 to 192 GB.






36. Aka uniqueness database file.






37. Aka emergency repair disk.






38. In an IP configuration - the address of the local router that acts as a gateway from the local network to other IP networks.






39. Aka access control entry.






40. A pointing device built into some laptop keyboards. It appears to be a very tiny joystick-type button that barely protrudes above the level of the keys.






41. 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.






42. An organization that created several PC standards - including the VGA connector.






43. 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.






44. The box that houses the main computer system.






45. Aka musical instrument digital interface.






46. The traditional wired telephone network.






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






48. In the laser printing process - the step in which the laser beam creates a negative of the image that will eventually appear on the printout. Each place that the laser beam touches loses most of its charge - creating an image - whereas the rest of th






49. A pixel that is permanently turned on - causing the pixel to show constantly as red - green - or blue. Also called a stuck pixel.






50. The smallest laptop type - weighing less than 3 pounds. Aka also netbook and mini-notebook.
