2. 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






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






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






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






7. 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. The latest SCSI standard - serial SCSI - also called serial attached SCSI - allows for more than 15 devices on a single SCSI chain - uses smaller - longer - round cables - and uses smaller hard drive form factors that can support larger capacities th






11. 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.






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






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

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






18. 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.






19. 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






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

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






25. 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






26. 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.






27. 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.






28. 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.






29. 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.






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






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






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






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






34. 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.






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






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






37. A___________________can be used to test a USB port.






38. 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:






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






40. 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?

43. 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.






44. 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
