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. 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.






2. 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






3. 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.






4. 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.






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






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






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






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






9. Windows Vista technology that supports a hybrid drive.






10. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






12. 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.






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






14. Temporary drop in AC power.






15. 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.






16. 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.






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






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. Used to repair and reinstall Windows






20. A method of data transfer between hard drive and memory that allows multiple data transfers on a single software interrupt.






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. 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.






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






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






25. 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.






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






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






28. 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






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






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






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






33. 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.






34. 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






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






36. POST means __________________.






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






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






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






40. 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:






41. 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.






42. 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.






43. 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.






44. 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.






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. 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.






47. 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.






48. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






49. This is how the BIOS communicates errors during POST






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