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






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






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






4. 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?






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






6. Network with each computer






7. 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.






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






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






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






11. A drive with one - two - or more platters - or disks that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bot






12. Temporary drop in AC power.






13. 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.






14. Standard computer case form factor for modern computers.






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






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






17. 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.






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






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






20. 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.






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






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






23. 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.






24. 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.






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






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






28. 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.






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






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






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






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






33. 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






34. __________________cards report computer errors and conflicts at POST.






35. 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?






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






37. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






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






39. 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.






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






41. POST means __________________.






42. This is how the BIOS communicates errors during POST






43. 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.






44. 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






45. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






46. 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.






47. 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.
