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






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






3. 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.






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






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






6. 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.






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






8. 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






9. 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.






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






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






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






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






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






15. 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.






16. 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






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






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






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






20. 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.






21. 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.






22. 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.






23. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






24. 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.






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






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






27. 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






28. Used to repair and reinstall Windows






29. A set of tools - routines and protocols used to develop software applications that will be compatible with an operating system.






30. 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.






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






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






33. 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.






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






35. 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.






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






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






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






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






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






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






42. 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.






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






44. 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.






45. The volume is assigned a drive letter (such as drive C: or drive D:) and is formatted using a file system. Also called simple volume.






46. The one bootable partition.






47. __________________cards report computer errors and conflicts at POST.






48. 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






49. A___________________can be used to test a USB port.






50. 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?
