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. Standard that specifies full SATA cabling for external disks.






2. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






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






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






5. 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.






6. Memory that does not lose its data when the power is turned off.






7. 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?






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






9. A Data Link layer device that connects and passes frames between two network segments. The frames are filtered and forwarded using MAC addresses.






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






11. Uses space from two or more physical disks to increase the disk space available for a single volume. THIS writes to the physical disks evenly across all disks so that no one disk receives all the activity - and therefore improves performance. Windows






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






13. Network with each computer






14. The overall structure an OS uses to name - store - and organize files on a drive. In it - a cluster is the smallest unit of space on a disk for storing a file and is made up of one or more sectors. A it tracks how these clusters are used for each fil

19. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi






20. Media through which data is transferred from one part of a computer to another. The bus can be compared to a highway on which data travels within a computer.






21. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






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






23. An interface standard - part of the IDE/ATA standards - that allows tape drives - CD-ROM drives - and other drives to be treated like an IDE hard drive by the system.






24. A drive that uses both solid state and magnetic technologies.






25. Command used to check the integrity of files and folders on a hard drive by scanning the disk surface for physical errors.






26. 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?






27. 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.

29. Temporary drop in AC power.






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






31. The one bootable partition.






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






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