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






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






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






4. Temporary drop in AC power.






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






6. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






7. __________________cards report computer errors and conflicts at POST.






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






9. 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






10. 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.






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






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






13. 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.






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






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






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






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






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






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






20. 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.






21. Formatting performed by means of the DOS or Windows Format program (for example - FORMAT C:/S creates the boot record - FAT - and root directory on drive C and makes the drive bootable). Also called OS formatting.






22. This is how the BIOS communicates errors during POST






23. 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.






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






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






26. 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.






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






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






29. 20-pin or 24-pin internal power supply connector.






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






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






32. 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






33. 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.






34. 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.






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






36. A___________________can be used to test a USB port.






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






38. Another name for the primary volume.






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






40. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






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






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






43. 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.






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






45. 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.






46. Network with each computer






47. 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?






48. 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:






49. Windows Vista technology that supports a hybrid drive.






50. A fast interface between a host adapter and the CPU that can daisy chain as many as 7 or 15 devices on a single bus.
