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 Internet service provider.






2. The type of connector used in the ExpressCard interface.






3. A marriage of SCSI and Serial ATA - this uses a serial interface to a SCSI bus.






4. The appropriate responses that you make during a conversation.






5. A magnetic mass storage device primarily used for backing up data from computers.






6. A set of skills - behaviors - and attitudes to use when listening to another person.






7. A method for supporting up to 8.3 GB capacity hard drives. Both the BIOS and hard drive system must use LBA.






8. The process that authenticates a user and verifies the user account's level of access to a resource.






9. A heat dissipation device - usually a passive metal object with a flat surface attached to a component - such as a chip.






10. The fine copper lines that are the electronic circuits through which power - data - and control signals travel on a circuit board.






11. A practice begun in Windows 2000 in which all of the operating system code is digitally signed to show that it has not been tampered with.






12. A drive that can write once to a special CD-R disc.






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






14. 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.






15. Aka thread.






16. Any video adapter or monitor that exceeds the VGA standard in resolution and color depth with a maximum resolution of 1600






17. A partition type on a basic disk that can have only one logical drive assigned to it encompassing the entire partition. This partition type is also the only type of partition on a basic disk that can be marked as active for booting up an operating sy






18. A version of the FAT file system used by hard drives and some flash drives (thumb drives - etc.) - using a 32-bit file allocation table.






19. A server containing source files for installing software onto client computers. The shared folder containing these files is a software distribution point.






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






21. Aka Voice over IP (VoIP).






22. 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.






23. Aka Fast Ethernet.






24. An obsolete video standard introduced with IBM PS/2 computers in the late 1980s. VGA had a maximum resolution of 720






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






26. An early technology for increasing the performance of DRAM.






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






28. Aka digitizing tablet.






29. A portion of a computer's chipset that controls communications between the CPU and such I/O busses as USB - IDE - PS2 - SATA - and others.






30. [1] On computer circuit boards - a very tiny slide that indicates two states.. [2] In a network - a network device - much like a hub - except that a switch takes an incoming signal and sends it to only the destination port - avoiding collisions and m






31. Aka Encrypting File System (EFS).






32. A unit of measurement of actual delivered power - calculated by the formula watts = volts






33. Aka Wireless Fidelity.






34. The protocol used by DHCP servers and clients. A DHCP server allocates IP addresses within the scope of addresses configured on the server by an administrator. DHCP clients request IP addresses and other IP configuration settings from DHCP Servers.






35. A protocol that transfers e-mail messages between mail servers. Clients also use this protocol to send e-mail to mail servers.






36. A command-line utility - installed with the TCP/IP protocol suite - that is used to troubleshoot DNS problems by querying DNS name servers and displaying the results of the queries.






37. A RAID array in which every time data is written to disk - a portion (block) is written to each disk in turn - creating a "stripe" of data across the member disks. RAID 0 uses the total disk space in the array for storage - without protecting the dat






38. An optical disc created and read by a mechanism using a laser.






39. The worldwide interconnection of networks that can be accessed with various Internet-based software. The World Wide Web is one of the many services of the Internet.






40. A measurement of the volume of electrons - also called current. It is calculated with the formula amps = watts / volts.






41. A disk that uses basic storage - which means that it uses the partition table in the master boot record (MBR) to define disk partitions.






42. This attack occurs when someone sends a large number of requests to a server - overwhelming the server so it stops functioning on the network.






43. A RAM standard that replaces the original DDR standard. Using far less power than DDR1 - a stick of DDR2 SDRAM has 240 pins.






44. [1] A device that is the central connecting point of a LAN. A hub is little more than a multiport repeater taking incoming signals on one port and repeating them to all other ports. Ethernet hubs have been largely replaced by Ethernet switches.. [2]






45. A technology for ROM that can be reprogrammed using special software.






46. An early method for addressing the disparity between the drive geometry supported by PC BIOSs and the physical geometry of drives.






47. A special substance - also called thermal paste or heat sink compound - that increases the heat conductivity between a fan or heat sink and a chip.






48. In the laser printing process - a blade that removes residual toner from the drum.






49. 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.






50. A set of wires used by data traveling into and out of a processor.
