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






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






5. 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.






6. 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.






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






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






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






10. 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.

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






15. 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.






16. The one bootable partition.






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

21. POST means __________________.






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






24. Fastener used to bundle cables inside and outside of a computer.






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






26. Troubleshooting tool that allows the computer to boot from a disk when the hard drive will not boot.






27. Network with each computer






28. 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.






29. Four Main Parts of the boot process: 1. BIOS checks hardware through POST. 2. The ___________ searches for and loads an OS. 3. The OS configures the system and completes its own loading. 4. The user executes application software.






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






31. 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?






32. 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:






33. The process - you specify the size of the partition and what file system it will use.






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






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






36. 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?






37. Used to repair and reinstall Windows






38. 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.






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






40. 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






41. 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.






42. This is how the BIOS communicates errors during POST






43. 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






44. 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






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






46. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A
