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






2. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






3. A sealed - magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.






4. 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.






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






6. 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






7. 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.






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






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






10. 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.






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






12. 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






13. 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.






14. POST means __________________.






15. 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.






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






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






18. A___________________can be used to test a USB port.






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






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






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






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






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






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






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






26. 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.






27. 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.






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






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






30. Another name for the primary volume.






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






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






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






34. 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?






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






36. 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






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






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






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






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






41. 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.






42. 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.






43. 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






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






45. __________________cards report computer errors and conflicts at POST.






46. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






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






48. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






49. Standard computer case form factor for modern computers.






50. This is how the BIOS communicates errors during POST
