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






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






3. 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.






4. 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:






5. 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.






6. 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.






7. 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.






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






9. 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






10. Windows Vista technology that supports a hybrid drive.






11. 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.






12. Network with each computer






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






14. 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.






15. 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.






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






17. The one bootable partition.






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






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






20. 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






21. POST means __________________.






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






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






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






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






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






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






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






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






30. 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






31. 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.






32. 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






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. Temporary drop in AC power.






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






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






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






38. Used to repair and reinstall Windows






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






40. 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






41. 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.






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






43. 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.






44. 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.






45. 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?






46. 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.






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






48. This is how the BIOS communicates errors during POST






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






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