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






2. The resistor added at the end of a SCSI chain to dampen the voltage at the end of the chain.






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






4. 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






5. 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.






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






7. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






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






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






10. 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.






11. Another name for the primary volume.






12. 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.






13. 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






14. Temporary drop in AC power.






15. Standard computer case form factor for modern computers.






16. 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.






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






18. 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?






19. 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.






20. 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.






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






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






23. 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.






24. High-speed - 32-bit bus technology designed to support the acceleration of 3D computer graphics.






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






26. 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.






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






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






29. 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:






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






31. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






32. 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






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






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






35. This is how the BIOS communicates errors during POST






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






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






38. 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.






39. 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.






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






41. Used to repair and reinstall Windows






42. 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.






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. 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






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






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






47. 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






48. 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






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






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