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






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






3. 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.






4. 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






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






6. 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.






7. 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?






8. 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.






9. Standard computer case form factor for modern computers.






10. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






12. 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.






13. 20-pin or 24-pin internal power supply connector.






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






15. 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.






16. 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.






17. 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






18. 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.






19. 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.






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






21. 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.






22. A number from 0 to 15 assigned to each SCSI device attached to the daisy chain.






23. 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

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






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






29. Network with each computer






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






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






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






33. 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.






34. 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






35. Temporary drop in AC power.






36. 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.






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






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






39. 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.






40. 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






41. A single hard drive that works independently of other hard drives.






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






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






44. POST means __________________.






45. 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.
