Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 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.






2. 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.






3. 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:






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. 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.






6. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






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






8. 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






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






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






11. 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.






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






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






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






15. 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.






16. Another name for the primary volume.






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






18. 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.






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






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. 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






22. __________________cards report computer errors and conflicts at POST.






23. 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.






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






25. 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.






26. 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.






27. Speed at which bits are transmitted - usually expressed in bits per second (bps).






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






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






30. 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.






31. 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.






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






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






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






35. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






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






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






38. Windows Vista technology that supports a hybrid drive.






39. 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






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






41. Backs up user-selected files to tape. This backup does not reset the archive bit.






42. The one bootable partition.






43. Uses space from two or more physical disks to increase the disk space available for a single volume. THIS writes to the physical disks evenly across all disks so that no one disk receives all the activity - and therefore improves performance. Windows






44. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






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






46. 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.






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






48. 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.






49. Temporary drop in AC power.






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