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. To power up a computer from the off position.






2. 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






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






4. 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.






5. 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.






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






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






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






9. Another name for the primary volume.






10. 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.






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






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






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






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






15. The term__________refers to the computer bringing itself up to a working state without the user having to do anything but press the on button.






16. 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.






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






18. 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.






19. 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.






20. This can be divided into one or more logical drives. Each logical drive is assigned a drive letter (such as drive G:) and is formatted using its own file system.






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






22. A table on a hard drive or floppy disk that tracks how space on a disk is used to store files.






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






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 drive with no moving parts. Uses nonvolatile flash memory.






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






27. 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.






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






29. 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?






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






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






32. 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.






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






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






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






36. 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.






37. This is how the BIOS communicates errors during POST






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






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






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






41. Temporary drop in AC power.






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






44. 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.






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






46. 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.






47. 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?






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






49. 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.






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