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






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






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






4. 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






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






6. 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.






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






8. 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.






9. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






10. 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.






11. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






13. 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.






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






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






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






17. 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






18. 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?






19. Another name for the primary volume.






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






21. Temporary drop in AC power.






22. 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.






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






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






25. 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.






26. 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.






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






28. 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.






29. 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.






30. 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:






31. 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






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






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






34. Used to repair and reinstall Windows






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






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






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






38. 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.






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






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






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






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






43. 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.






44. 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.






45. 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






46. Windows Vista technology that supports a hybrid drive.






47. 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.






48. 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






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






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