Subject : it-skills
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. 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






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






3. 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?






4. 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.






5. 20-pin or 24-pin internal power supply connector.






6. 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.






7. POST means __________________.






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






9. 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.






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






11. 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.






12. 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.






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






14. Temporary drop in AC power.






15. 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






16. 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






17. 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.






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






19. 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






20. 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.






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






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






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






24. 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






25. 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.






26. Standard computer case form factor for modern computers.






27. 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.






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






29. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






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






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






32. Windows Vista technology that supports a hybrid drive.






33. __________________cards report computer errors and conflicts at POST.






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






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






37. A transfer mode that uses the CPU to transfer data from the hard drive to memory. This mode is slower than DMA mode.






38. Network with each computer






39. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






41. 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?






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






43. 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.






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






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






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






47. 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.






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






49. 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:






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