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. 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






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






3. 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






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






5. 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.






6. 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.






7. __________________cards report computer errors and conflicts at POST.






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






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






10. 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






11. 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:






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






13. POST means __________________.






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






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






16. 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.






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






18. Standard computer case form factor for modern computers.






19. 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.






20. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






23. 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






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






25. A___________________can be used to test a USB port.






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






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






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






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






30. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.






31. 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






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






33. 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.






34. Windows Vista technology that supports a hybrid drive.






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






36. 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.






37. 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.






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






39. 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.






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






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 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.






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






44. 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?






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






46. The duplication of everything written to a hard drive.






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






48. 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.






49. The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain.






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