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. 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.






2. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






3. The one bootable partition.






4. Windows Vista technology that supports a hybrid drive.






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






6. 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.






7. 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?






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. 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:






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






11. Fastener used to bundle cables inside and outside of a computer.






12. 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






13. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






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






15. 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.






16. This tool can be used to test a USB port.






17. A___________________can be used to test a USB port.






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






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






20. 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.






21. This is how the BIOS communicates errors during POST






22. 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






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






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






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






26. 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?






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






28. 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.






29. 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.






30. 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.






31. 20-pin or 24-pin internal power supply connector.






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






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






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






35. 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.






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






37. 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.






38. 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.






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






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






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






42. Standard computer case form factor for modern computers.






43. Temporary drop in AC power.






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






45. 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.






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






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






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






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






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