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






2. This is how the BIOS communicates errors during POST






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






4. 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.






5. Temporary drop in AC power.






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






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






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






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






10. 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






11. 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






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






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






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






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






16. How do you change a computer's Boot Sequence?






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






18. Used to repair and reinstall Windows






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






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






21. 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






22. 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.






23. A___________________can be used to test a USB port.






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. 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.






26. 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:






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






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






29. 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.






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






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






32. 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.






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






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






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






36. Network with each computer






37. 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.






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






39. 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.






40. A hard drive whose disk controller is integrated into the drive - eliminating the need for a controller cable and thus increasing speed - as well as reducing price.






41. 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?






42. Another name for the primary volume.






43. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






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






45. 20-pin or 24-pin internal power supply connector.






46. 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.






47. 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






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






49. Standard computer case form factor for modern computers.






50. 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.
