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. Another name for the primary volume.






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






3. 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.






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. The one bootable partition.






6. This is how the BIOS communicates errors during POST






7. 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.






8. 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.






9. One or more sectors that constitute the smallest unit of space on a disk for storing data (also referred to as a file allocation unit). Files are written to a disk as groups of whole clusters.






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






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






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






13. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






14. 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:






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






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






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






18. POST means __________________.






19. 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.






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






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






22. 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.






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






24. 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






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. Standard that specifies full SATA cabling for external disks.






27. 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.






28. 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.






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






30. 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






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






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






33. 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.






34. 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






35. Standard computer case form factor for modern computers.






36. 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






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






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






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






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






41. 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.






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






43. 20-pin or 24-pin internal power supply connector.






44. 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.






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






46. 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






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






48. 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






49. Temporary drop in AC power.






50. 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.
