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






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






3. 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.






4. Performed from the operating system - such as by pressing the key combination Ctrl+Alt+Del or by choosing a Restart option from the Shut Down dialog box. Less stressful on the computer.






5. 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






6. 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.






7. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






9. 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.






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






11. Five possible questions that should be asked of a user who is experiencing computer problems: What had just happened? What recent changes did the user make? When did the computer __________? What error message do you see?






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






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






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






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






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






17. 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?






18. 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.






19. 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.






20. 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.






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






22. 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






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






24. 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.






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






26. This is how the BIOS communicates errors during POST






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






28. 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.






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






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






31. 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.






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






33. Used to repair and reinstall Windows






34. 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.






35. 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






36. 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






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






39. 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






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






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






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






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






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






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






46. 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.






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






48. 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.






49. The one bootable partition.






50. A computer's ability to respond to a fault or catastrophe - such as a hardware failure or power outage - so that data is not lost.
