Subject : it-skills
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. This tool can be used to test a USB port.






2. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






3. 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.






4. Another name for the primary volume.






5. This is how the BIOS communicates errors during POST






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






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






8. 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






9. 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?






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






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






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. 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






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






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






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






17. 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






18. 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?






19. 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.






20. 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.






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






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






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






24. 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.






25. 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.






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






27. The advantages of ______________: To reduce the likelihood that the events that causes PC failures will occur and to lessen the damage if they do.






28. 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.






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






30. 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.






31. A___________________can be used to test a USB port.






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






33. 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.






34. Temporary drop in AC power.






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






36. 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.






37. 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:






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






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






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






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






42. To power up a computer from the off position.






43. The one bootable partition.






44. 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.






45. Windows Vista technology that supports a hybrid drive.






46. 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.






47. 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.






48. 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.






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






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