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 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






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






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






4. Order of drives checked for an OS. Example: Floppy (1st) - CD-ROM (2nd) Hard Drive (3rd)






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






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






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






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






9. 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






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






11. 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:






12. 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?






13. 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.






14. Standard computer case form factor for modern computers.






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






16. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






17. 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






18. 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.






19. 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.






20. 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






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






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






24. The one bootable partition.






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






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






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






28. 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.






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






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






31. Used to repair and reinstall Windows






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






33. 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






34. 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.






35. 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






36. 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.






37. 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






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






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






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






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






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. 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.






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






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






46. Temporary drop in AC power.






47. __________________cards report computer errors and conflicts at POST.






48. 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.






49. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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