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






2. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






3. 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.






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






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






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






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






9. Windows Vista technology that supports a hybrid drive.






10. POST means __________________.






11. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






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






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






14. Another name for the primary volume.






15. 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.






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






17. Temporary drop in AC power.






18. 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






19. 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.






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






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






22. 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.






23. The one bootable partition.






24. Network with each computer






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






26. 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.






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






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






29. 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?






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






31. 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.






32. 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:






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






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






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






37. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






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






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






40. 20-pin or 24-pin internal power supply connector.






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






42. 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.






43. __________________cards report computer errors and conflicts at POST.






44. 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.






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

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






48. 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.






49. 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






50. 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.
