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






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






3. __________________cards report computer errors and conflicts at POST.






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






5. Windows Vista technology that supports a hybrid drive.






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






7. 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.






8. This is how the BIOS communicates errors during POST






9. 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.






10. 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.






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






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






13. 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






14. 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.






15. 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






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






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






18. 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.






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






20. 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.






21. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






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






23. 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.






24. 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.






25. Used to repair and reinstall Windows






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






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






28. An IDE cable that has 40 pins but uses 80 wires - 40 of which are ground wires designed to reduce crosstalk on the cable.






29. 20-pin or 24-pin internal power supply connector.






30. A set of tools - routines and protocols used to develop software applications that will be compatible with an operating system.






31. 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.






32. 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






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






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






35. Another name for the primary volume.






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






37. 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






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






39. Standard computer case form factor for modern computers.






40. A___________________can be used to test a USB port.






41. 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






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






43. 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






44. 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.






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






46. Network with each computer






47. 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.






48. 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.






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






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