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. 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






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






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






4. 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.






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






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






7. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






8. 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.






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






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






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






12. 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.






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






14. 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.






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






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






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






18. 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.






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






20. 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.






21. 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.






22. 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






23. Used to repair and reinstall Windows






24. 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?






25. 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.






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






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






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






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






30. __________________cards report computer errors and conflicts at POST.






31. 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






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






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






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






35. A___________________can be used to test a USB port.






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






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






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






39. Windows Vista technology that supports a hybrid drive.






40. Temporary drop in AC power.






41. 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.






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






43. 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






44. 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.






45. 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.






46. The process - you specify the size of the partition and what file system it will use.






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






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