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. 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?






2. 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






3. Windows Vista technology that supports a hybrid drive.






4. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






5. 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






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






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






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






9. A hard drive whose disk controller is integrated into the drive - eliminating the need for a controller cable and thus increasing speed - as well as reducing price.






10. A number from 0 to 15 assigned to each SCSI device attached to the daisy chain.






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






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






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






14. Another name for the primary volume.






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






16. 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.






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






18. 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.






19. A unit of measure that describes the size of a data file - the amount of space on a disk or other storage medium - or the amount of data being sent over a network. One byte consists of 8 bits of data.






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






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






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






23. 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?






24. 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.






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






26. 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.






27. The one bootable partition.






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






29. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.






30. 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.






31. How do you change a computer's Boot Sequence?






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






33. A___________________can be used to test a USB port.






34. A________________CD can be used to boot a system and repair or reinstall Windows.






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






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






37. This is how the BIOS communicates errors during POST






38. To power up a computer from the off position.






39. A drive with one - two - or more platters - or disks that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bot






40. Standard computer case form factor for modern computers.






41. 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.






42. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






43. 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.






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






45. 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.






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






47. 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.






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