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






2. 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.






3. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






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






5. 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






6. 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






7. Another name for the primary volume.






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






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






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






11. Windows Vista technology that supports a hybrid drive.






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






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






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






15. Network with each computer






16. POST means __________________.






17. 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?






18. 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.






19. 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.






20. 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.






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






22. 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.






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






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






25. 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






26. 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.






27. A drive that uses both solid state and magnetic technologies.






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






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






30. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






32. 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.






33. 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.






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






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






36. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






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. 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.






39. 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






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






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






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






43. 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.






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






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






46. __________________cards report computer errors and conflicts at POST.






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






48. 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






49. 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.






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