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. Network with each computer






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






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






4. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






5. 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






6. 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






7. 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.






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






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






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






11. 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.






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






13. 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.






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






15. The one bootable partition.






16. 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.






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






19. POST means __________________.






20. 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






21. Used to repair and reinstall Windows






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






23. 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:






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






25. 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.






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






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






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






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






30. Windows Vista technology that supports a hybrid drive.






31. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






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






33. Speed at which bits are transmitted - usually expressed in bits per second (bps).






34. 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.






35. 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?






36. 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






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






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






39. 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.






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






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






42. 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.






43. 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






44. Temporary drop in AC power.






45. 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






46. 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.






47. 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.






48. 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.






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






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