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. 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






2. 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






3. Used to repair and reinstall Windows






4. 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.






5. Temporary drop in AC power.






6. 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.






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






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






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






10. 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.






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






12. 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.






13. Network with each computer






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






15. 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.






16. 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.






17. 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.






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






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






20. 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






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






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






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






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






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






26. Standard computer case form factor for modern computers.






27. 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.






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






29. In Windows XP - you should choose the _______________setting for updates.






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






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






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






33. 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.






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






35. 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.






36. 20-pin or 24-pin internal power supply connector.






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






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






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






41. Windows Vista technology that supports a hybrid drive.






42. Another name for the primary volume.






43. 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






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






46. 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.






47. 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






48. 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.






49. 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.






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