1. 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.






2. 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.

5. 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






6. 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






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






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






9. 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?






10. 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.






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






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






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






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






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






16. 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.






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






18. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






19. 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.






20. 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.






21. 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






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






23. 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?






24. Network with each computer






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






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






27. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






28. 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.






29. Applet or small program created by Microsoft to control interactivity on web pages that has to be downloaded to gain access to the full functionality.






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






31. 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.






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






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






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






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






36. Standard computer case form factor for modern computers.






37. 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.






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






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






40. 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.






41. 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.






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. 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.






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






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






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






47. 20-pin or 24-pin internal power supply connector.
