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. Temporary drop in AC power.






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






3. 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.






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






5. 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.






6. 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.






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






8. 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.






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






10. 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.






11. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






12. 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.






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






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






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






16. This is how the BIOS communicates errors during POST






17. 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.






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






19. 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






20. Standard computer case form factor for modern computers.






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






22. 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.






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






24. Storage area used for handling data in transit. Buffers are used in internetworking to compensate for differences in processing speed between network devices. Bursts of data can be stored in buffers until they can be handled by slower processing devi






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






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






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






28. 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.






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






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






31. 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.






32. 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.






33. 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.






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






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






36. 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.






37. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






40. 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






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






42. __________________cards report computer errors and conflicts at POST.
