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. 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






2. 20-pin or 24-pin internal power supply connector.






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






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






5. 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






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






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






8. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






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






10. Another name for the primary volume.






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






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






13. This is how the BIOS communicates errors during POST






14. POST means __________________.






15. 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.






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






17. 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.






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






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. 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.






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






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. To power up a computer from the off position.






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






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






26. Network with each computer






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






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






29. 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.






30. 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.






31. 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






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






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






34. __________________cards report computer errors and conflicts at POST.






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






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






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






39. 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.






40. 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.
