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. 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






2. 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.






3. 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?






4. 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.






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






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






7. 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






8. 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






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






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






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






12. 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:






13. 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.






14. 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






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






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






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






19. 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.






20. POST means __________________.






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. Backs up user-selected files to tape. This backup does not reset the archive bit.






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






24. 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.






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






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






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






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






29. 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.






30. 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.






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






32. This is how the BIOS communicates errors during POST






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






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






35. 20-pin or 24-pin internal power supply connector.






36. 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?






37. Commonly called the host adapter. The host adapter is inserted into an expansion slot on the motherboard and is responsible for managing all devices on the SCSI bus. A host adapter can support both internal and external SCSI devices - using one conne






38. 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






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






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






41. 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.






42. 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.






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






44. 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.






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






46. 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.






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






48. 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.






49. __________________cards report computer errors and conflicts at POST.






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