1. 20-pin or 24-pin internal power supply connector.






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






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. 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.






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






6. 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






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






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






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






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






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






12. 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.






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






14. 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






15. 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.






16. Network with each computer






17. 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.






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






19. POST means __________________.






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






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






22. 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.






23. 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.






24. 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.






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






26. 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






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






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






29. 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.






30. 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.






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






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






33. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






34. 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.






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






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






37. 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.






38. 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






39. Data storage area that provides high-speed access for the system.






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






41. A transfer mode used by devices - including the hard drive - to transfer data to memory without involving the CPU.






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






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