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 Control Message Protocol.






2. Aka uniqueness database file.






3. A metal plate behind the front of a CRT monitor that focuses the electron beams from the gun.






4. A service implemented on Windows Servers that hides the complexity of the network from end users in that it makes files that are distributed across multiple servers appear as if they are in one place.






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






6. A storage type in Windows that uses the partition table in the master boot record (MBR) to define disk partitions.






7. Not revealing information about someone that would be harmful to or embarrass him or her.






8. Aka liquid crystal display.






9. Aka floating-point unit.






10. Aka central processing unit.






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






12. A utility that provides remote terminal emulation for connecting to computers and network devices running server software that can respond - without needing to be concerned with the actual operating system running on either system.






13. 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.






14. A power management standard that includes all the power states of APM - plus two more. It also supports soft power.






15. A system by which the computer BIOS and operating system recognizes a device and the operating system automatically installs and configures a device driver.






16. Aka S-Video.






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






18. A memory error-checking method in which the parity bit is used to ensure that the total number of 1s in the data stream is odd.






19. A riser card standard that AMD - 3Com - and others introduced in 2000 to supersede AMR. It uses one PCI slot - provides accelerated audio and modem functions as well as networking - and supports multiple Ethernet NICs.






20. The practice of applying a digital signature to device driver code.






21. Aka video RAM.






22. A CPU technology that allows two threads to execute at the same time within a single execution core. This technology is considered to be partially parallel execution. Intel introduced it in the Pentium 4 Xeon CPU. Also known as simultaneous multithre






23. A group of networking standards created by the IEEE 802.3 subcommittee.






24. The delivery of electricity (as from a wall outlet) in which the flow of electrons reverses periodically and has alternating positive and negative values.






25. A version of the FAT file system for very small drives






26. A measurement of a body part - such as a fingerprint or retina scan.






27. Light waves in the infrared spectrum.






28. A video mode with a maximum graphics resolution of 1024






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






30. 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






31. Aka audio modem riser.






32. Aka Internet Message Access Protocol (IMAP).






33. Aka enhanced parallel port (EPP) mode.






34. A technology that makes 802.11n speeds possible - using multiple antennas to send and receive digital data in simultaneous radio streams that increases performance.






35. A Windows Advanced Options menu choice used to send debugging information about the Windows startup over a serial cable to another computer running a special program called a debugger.






36. A device used with a laptop. The port replicator remains on the desktop with external devices connected to ports on it. A laptop then needs only one connection to the port replicator to have access to the peripherals.






37. A process that places the logical structure of a file system on a partitioned volume.






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






39. A non-routable network protocol suite for use only in small networks.






40. In the laser printing process - the step in which the toner on the drum is transferred to the paper.






41. A TCP/IP protocol developed as a solution to the dwindling number of IP addresses on the Internet and that also serves to hide IP addresses on a private network from the Internet.






42. Aka floppy disk drive.






43. 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").






44. A variety of persuasion techniques used for many purposes






45. A circuit card in a PC that controls the output to the display device(s).






46. In Microsoft Windows - NTFS permissions are used to specify and control which users and groups can access certain files and folders and what each user or group can do with them.






47. An Advanced Options menu choice that simply causes Windows to restart normally (if it can).






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






49. A Windows server running the WINS service to maintain and resolve NetBIOS names.
