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. The duplication of everything written to a hard drive.






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






3. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






5. 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.






6. 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.






7. When troubleshooting a failed boot - if you do not see any lights or hear any noises - what hardware system do you first assume is at fault?






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






9. Another name for the primary volume.






10. 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.






11. 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.






12. 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






13. The one bootable partition.






14. 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






15. Temporary drop in AC power.






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






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






18. 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.






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






20. 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.






21. Used to repair and reinstall Windows






22. 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.






23. 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.






24. 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.






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






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






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






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






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






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






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






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






33. 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.






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






35. 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.






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






37. A___________________can be used to test a USB port.






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






39. 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.






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






41. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






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






44. 20-pin or 24-pin internal power supply connector.






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






46. A transfer mode used by devices - including the hard drive - to transfer data to memory without involving the CPU.






47. 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.






48. 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.






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






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