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. 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.






2. 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






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






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

6. 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:






7. 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






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






9. Used to repair and reinstall Windows






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






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

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






14. 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






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






17. 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.






18. 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.






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






20. POST means __________________.






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






22. Fastener used to bundle cables inside and outside of a computer.






23. A set of tools - routines and protocols used to develop software applications that will be compatible with an operating system.






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






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






26. 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.






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






28. Temporary drop in AC power.






29. 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.






30. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






32. A drive with one - two - or more platters - or disks that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bot






33. 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.






34. 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.






35. The one bootable partition.






36. 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.






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






38. 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.






39. 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.






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






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






42. 20-pin or 24-pin internal power supply connector.






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






44. 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






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






46. Network with each computer






47. 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.






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