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. Network with each computer






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






3. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






4. 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.






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






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






7. Windows Vista technology that supports a hybrid drive.






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. 20-pin or 24-pin internal power supply connector.






10. 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?






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






12. 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.






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






14. 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?






15. 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:






16. POST means __________________.






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






18. 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.






19. This is how the BIOS communicates errors during POST






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






22. 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






23. Another name for the primary volume.






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






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






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






27. 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.






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






29. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






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






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






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






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






34. Four Main Parts of the boot process: 1. BIOS checks hardware through POST. 2. The ___________ searches for and loads an OS. 3. The OS configures the system and completes its own loading. 4. The user executes application software.






35. 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.






36. Standard computer case form factor for modern computers.






37. __________________cards report computer errors and conflicts at POST.






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






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






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






41. Temporary drop in AC power.






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






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






44. 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.






45. 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






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






47. 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.
