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 disc drive that uses laser technology to read and/or write to special discs.






2. Aka wireless access point.






3. In reference to parallel ports - a mode in which the parallel device connected to the parallel port can receive data but cannot send data. CMOS settings (system settings) may refer to this mode as "Transfer only."






4. Aka IEEE 1394.






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






6. In the laser printing process - this is the step in which the cover on the printer's toner cartridge is opened and the toner particles are attracted to the relatively less negatively charged areas of the drum.






7. In networks - when data can travel in either direction - but only in one direction at a time.






8. A wireless mode requiring a wireless access point (WAP).






9. Aka Domain Name Service.






10. In a low-profile PC case - a card that plugs into a motherboard to allow other cards to be inserted at a right angle to the riser card and parallel to the motherboard. Also - a single expansion card containing multiple functions - such as modem - sou






11. Aka uniqueness database file.






12. Aka Advanced Configuration and Power Interface.






13. A WAN connection that uses existing copper telephone wire for the communication circuit. To accomplish this - a DSL modem splits the existing phone line into two bands; voice transmission uses the frequencies below 4000 Hz - whereas data transmission






14. A generic term for a collection of information on known malware (not just viruses).






15. A subprotocol of TCP/IP used for connectionless communications in which each packet is sent without establishing a connection.






16. A laptop in which the display is an integrated digitizer.






17. When a mount point exists between a partition or volume to a folder on another volume - the drive path is the path (including a drive letter) to that partition or volume.






18. The redirection of incoming traffic to the requesting internal hosts that initiated the communication with an external host.






19. A power management standard - introduced by Intel in 1992 - that defines four power-usage operating levels.






20. A standards organization - of which the T10 SCSI committee maintains the SCSI standard.






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






22. The traditional transmission system for television video signals - which combines the color and brightness information with the synchronization data into one signal. The TV circuitry then separates the two signals from the composite signal.






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






24. A grouping of wires built into a PC that - based on certain protocols - transfers data - control signals - and power to printed circuit boards (adapter cards) that are plugged into connectors in the expansion bus. Technicians often use the termsexpan






25. Aka communication network riser.






26. 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.






27. A security account that exists in a local security accounts database.






28. A cooling fan located on a CPU.






29. Aka Wireless Fidelity.






30. Erasable programmable read-only memory. A ROM chip that is erasable and reprogrammable through the use of specialized software.






31. Aka Advanced Technology Attachment.






32. A password that meets certain criteria in order to be difficult to crack. One definition of a strong password is one that contains at least eight characters - includes a combination of letters - numbers - and other symbols ( _ - - - $ - and so on) an






33. A blanket term used for DVD discs regardless of the type of data they contain.






34. Aka MSCONFIG.






35. A scaled-down laptop in the ultra-portable category - designed for Internet access. Aka also ultra-portable and mini-notebook.






36. Aka Hypertext Markup Language (HTML).






37. An expansion bus architecture that uses serial communications rather than the parallel communications of PCI. Also called PCI Express and PCI-E.






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






39. A utility in Windows NT for gathering and viewing performance data involving memory - disks - processors - network - and other objectives.






40. A server running the Dynamic Host Configuration Protocol (DHCP) service. This server allocates IP addresses to DHCP client computers.






41. 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.






42. The high-definition optical disc formatting standard developed by the Blu-ray Disc Association whose members include Sony - 20th Century Fox - Dell - Hewlett-Packard - and many other industry leaders.






43. Programmable ROM. A ROM chip that can have programs added to it.






44. The displayable number of pixels - expressed as x and y numbers - such as 1024






45. The generic term for a pointing stick.






46. Aka Point-to-Point Tunneling Protocol.






47. A version of Windows XP that includes Windows Media Center - which supports advanced multimedia functions.






48. A wireless network standard that defines speeds of up to 600 Mbps. It is downward-compatible with 802.11a - 802.11b - and 802.11g.






49. The original digital discs created in 1995 for storing video.






50. In a laser printer - a wire that stretches across the printer's drum - not touching it - but positioned very close to the drum's surface so it can pass high voltage to the drum.
