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






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






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






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






5. 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.






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






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






8. 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.






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






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






11. 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.






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






13. Used to repair and reinstall Windows






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






15. 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.






16. 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






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






18. 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.






19. List managed by a network administrator that itemizes what a user is permitted to access and the type of access granted.






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






21. 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.






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






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






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






25. 20-pin or 24-pin internal power supply connector.






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






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






28. 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






29. The duplication of everything written to a hard drive.






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






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






32. Temporary drop in AC power.






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






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






35. Standard computer case form factor for modern computers.






36. The one bootable partition.






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






38. 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






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






40. 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.






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






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






43. This is how the BIOS communicates errors during POST






44. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






46. 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.






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






49. 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.






50. 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?
