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. 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.






3. A nonprofit organization dedicated to creating trade and communications standards.






4. 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.






5. 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






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






7. 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.






8. 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.






9. Used to repair and reinstall Windows






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






11. 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






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






13. 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






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






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






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






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. 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.






19. 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:






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






21. 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.






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






23. 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.






24. 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?






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






26. 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






27. 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






28. To power up a computer from the off position.






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






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






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

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. 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.






35. 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.






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






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






38. 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






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






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






41. 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
