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






2. 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.






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






4. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






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






6. 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.






7. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






8. 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






9. Data storage area that provides high-speed access for the system.






10. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






11. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






12. List managed by a network administrator that itemizes what a user is permitted to access and the type of access granted.






13. 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.






14. A method of data transfer between hard drive and memory that allows multiple data transfers on a single software interrupt.






15. The first sector of a floppy disk or logical drive in a partition; it contains information about the disk or logical drive. On a hard drive - if the THING is in the active partition - then it is used to boot the OS. Also called boot sector.






16. The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. This device controls communication between the SCSI bus and the PC.






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






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






19. Windows Vista technology that supports a hybrid drive.






20. A sealed - magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.






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






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






23. 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






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






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






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






27. 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.






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






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






30. 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






31. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






32. Standard computer case form factor for modern computers.






33. Used to repair and reinstall Windows






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






35. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






37. In Windows XP - you should choose the _______________setting for updates.






38. 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?






39. 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.






40. Protocol suite to network Macintosh computers. It is comprised of a comprehensive set of protocols that span the seven layers of the OSI reference model.






41. One or more sectors that constitute the smallest unit of space on a disk for storing data (also referred to as a file allocation unit). Files are written to a disk as groups of whole clusters.






42. 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?






43. Another name for the primary volume.






44. The one bootable partition.






45. 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.






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






47. 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.






48. A___________________can be used to test a USB port.






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






50. A fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus.
