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. The duplication of everything written to a hard drive.






2. 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.






3. 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






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






5. 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.






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






7. 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.






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






9. 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






10. A drive that uses both solid state and magnetic technologies.






11. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






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






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






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






15. 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.






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






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. 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






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






20. 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:






21. 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.






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






23. 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.






24. Another name for the primary volume.






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






26. 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.






27. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






28. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






30. The overall structure an OS uses to name - store - and organize files on a drive. In it - a cluster is the smallest unit of space on a disk for storing a file and is made up of one or more sectors. A it tracks how these clusters are used for each fil






31. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.






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






33. Used to repair and reinstall Windows






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






35. Temporary drop in AC power.






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






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






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






40. 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.






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






42. You should write down or backup changes to CMOS/BIOS setup ____________________.






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






44. 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.






45. 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






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






47. 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.






48. 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?






49. __________________cards report computer errors and conflicts at POST.






50. Windows Vista technology that supports a hybrid drive.
