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






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






3. 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?






4. 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.






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






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






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






8. 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






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






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






11. 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.






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






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






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






15. 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.






16. 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.






17. 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.






18. The one bootable partition.






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






20. 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.






21. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






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






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






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






25. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






26. Windows Vista technology that supports a hybrid drive.






27. 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.






28. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






30. 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.






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






32. 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.






33. Expansion card that increases the number of controllers and ports available on a computer.






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






35. 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






36. 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






37. 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.






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






39. 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:






40. 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.






41. 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.






42. 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.






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






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






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






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






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






48. 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.






49. 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






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