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?






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. 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.






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

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






13. 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.






14. 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.






15. 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.






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. 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






18. Windows Vista technology that supports a hybrid drive.






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. Standard computer case form factor for modern computers.






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






22. Network with each computer






23. 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






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






25. This is how the BIOS communicates errors during POST






26. 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






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






28. 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.






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






30. 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:






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






32. 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.






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






34. 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.






35. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






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






37. 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.






38. 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.






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






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






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






42. 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.






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






44. A drive with no moving parts. Uses nonvolatile flash memory.






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