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. 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






3. 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?






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






5. 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.






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






7. 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.






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






9. Layer 7 of the OSI reference model. This layer provides services to application processes such as electronic mail - file transfer - and terminal emulation that are outside of the OSI model. The application layer identifies and establishes the availab






10. 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.






11. Another name for the primary volume.






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






13. 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.






14. 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






15. 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.






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






17. 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:






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






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






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






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






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






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






24. 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.






25. 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.






26. 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






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






28. 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.






29. POST means __________________.






30. 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






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






32. Temporary drop in AC power.






33. This is how the BIOS communicates errors during POST






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






36. The one bootable partition.






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






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






39. Standard computer case form factor for modern computers.






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






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






42. 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.






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






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






45. 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.






46. 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.






47. Network with each computer






48. 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.






49. Windows Vista technology that supports a hybrid drive.






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