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






2. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






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






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






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






6. The process - you specify the size of the partition and what file system it will use.






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






8. Standard computer case form factor for modern computers.






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






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






11. 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.






12. 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.






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






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






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. 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






17. 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






18. Another name for the primary volume.






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






20. 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.






21. Network with each computer






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






23. POST means __________________.






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






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






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






27. 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?






28. 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.






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






30. 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.






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






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






33. Used to repair and reinstall Windows






34. 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






35. __________________cards report computer errors and conflicts at POST.






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






37. 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.






38. 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






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






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






41. 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:






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






43. Commonly called the host adapter. The host adapter is inserted into an expansion slot on the motherboard and is responsible for managing all devices on the SCSI bus. A host adapter can support both internal and external SCSI devices - using one conne






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






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






46. This is how the BIOS communicates errors during POST






47. Windows Vista technology that supports a hybrid drive.






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






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






50. 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.
