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






4. 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






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






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






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






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






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






10. 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.






11. 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

16. 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.






17. 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

22. 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






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






24. 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.






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

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






30. 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.






31. 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?






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






33. 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.






34. Used to repair and reinstall Windows






35. 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.






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






37. An interface standard - part of the IDE/ATA standards - that allows tape drives - CD-ROM drives - and other drives to be treated like an IDE hard drive by the system.






38. The one bootable partition.






39. Network with each computer






40. A Data Link layer device that connects and passes frames between two network segments. The frames are filtered and forwarded using MAC addresses.
