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. 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.






2. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






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






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






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






6. 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






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






8. 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.






9. 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.






10. 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.






11. 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






12. 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.






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






14. 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






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






16. 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.






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






18. 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.






19. 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






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






21. 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.






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






23. 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.






24. 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.






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






26. 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.






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






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






29. 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






30. __________________cards report computer errors and conflicts at POST.






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






32. 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






33. 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.






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






35. Network with each computer






36. 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.






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






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






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






40. 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






41. 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.






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






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






44. 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






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






46. A________________CD can be used to boot a system and repair or reinstall Windows.






47. 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






48. A___________________can be used to test a USB port.






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






50. 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.
