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






2. 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.






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






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






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






6. Stripes data across three or more drives and uses parity checking - so that if one drive fails - the other drives can re-create the data stored on the failed drive. Data is not duplicated - and - therefore - THIS makes better use of volume capacity.






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






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






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






10. 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






11. 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






12. 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:






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






14. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






15. 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.






16. The volume is assigned a drive letter (such as drive C: or drive D:) and is formatted using a file system. Also called simple volume.






17. 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?






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






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






20. 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.






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






22. 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.






23. A sealed - magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.






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






25. This is how the BIOS communicates errors during POST






26. 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.






27. Used to repair and reinstall Windows






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






29. 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.






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






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






32. 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.






33. 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.






34. 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.






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






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






37. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






38. 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.






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






40. 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






41. Network with each computer






42. 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.






43. 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






44. 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.






45. 20-pin or 24-pin internal power supply connector.






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






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






48. 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.






49. Temporary drop in AC power.






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