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___________________can be used to test a USB port.






2. A computer's ability to respond to a fault or catastrophe - such as a hardware failure or power outage - so that data is not lost.






3. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






4. Cable that contains four pairs of wires - with a maximum data rate of 1 Gbps.






5. The advantages of ______________: To reduce the likelihood that the events that causes PC failures will occur and to lessen the damage if they do.






6. Troubleshooting tool that allows the computer to boot from a disk when the hard drive will not boot.






7. Backs up user-selected files to tape. This backup does not reset the archive bit.






8. A transfer mode that uses the CPU to transfer data from the hard drive to memory. This mode is slower than DMA mode.






9. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






10. The ________________makes sure the computer meets the necessary system requirements and that all hardware is working properly before starting the remainder of the boot process.






11. You should write down or backup changes to CMOS/BIOS setup ____________________.






12. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






13. High-speed - 32-bit bus technology designed to support the acceleration of 3D computer graphics.






14. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






15. Formatting performed by means of the DOS or Windows Format program (for example - FORMAT C:/S creates the boot record - FAT - and root directory on drive C and makes the drive bootable). Also called OS formatting.






16. Five possible questions that should be asked of a user who is experiencing computer problems: What had just happened? What recent changes did the user make? When did the computer __________? What error message do you see?






17. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






18. The volume is assigned a drive letter (such as drive C: or drive D:) and is formatted using a file system. Also called simple volume.






19. Speed at which bits are transmitted - usually expressed in bits per second (bps).






20. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






21. The one bootable partition.






22. A single hard drive that works independently of other hard drives.






23. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






24. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






25. Layer 7 of the OSI reference model. This layer provides services to application processes such as electronic mail - file transfer - and terminal emulation that are outside of the OSI model. The application layer identifies and establishes the availab






26. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






27. When troubleshooting a failed boot - if you do not see any lights or hear any noises - what hardware system do you first assume is at fault?






28. The top or bottom surface of one platter on a hard drive. Each platter has two of these.






29. Network with each computer






30. Windows Vista technology that supports a hybrid drive.






31. A transfer mode used by devices - including the hard drive - to transfer data to memory without involving the CPU.






32. The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain.






33. Stripes data across three or more drives and uses parity checking - so that if one drive fails - the other drives can re-create the data stored on the failed drive. Data is not duplicated - and - therefore - THIS makes better use of volume capacity.






34. Involves restarting the computer by pressing the on/off switch. Stressful on computers.






35. Another name for the primary volume.






36. Is a type of drive imaging. It duplicates data on one drive to another drive and is used for fault tolerance.






37. Used to repair and reinstall Windows






38. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






39. A drive with no moving parts. Uses nonvolatile flash memory.






40. An ATAPI cabling method that uses a narrower and more reliable cable than the 80-conductor cable.






41. Expansion card that increases the number of controllers and ports available on a computer.






42. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






43. A nonprofit organization dedicated to creating trade and communications standards.






44. An IDE cable that has 40 pins but uses 80 wires - 40 of which are ground wires designed to reduce crosstalk on the cable.






45. The duplication of everything written to a hard drive.






46. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






47. Standard that specifies full SATA cabling for external disks.






48. The 12-bit wide - one-column file allocation table for a floppy disk - containing information about how each cluster or file allocation unit on the disk is currently used.






49. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






50. When two hard drives are configured as a single volume.
