Subject : it-skills
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. Another name for the primary volume.






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






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






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






5. 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.






6. 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.






7. 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.






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






9. 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.






10. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






11. Used to repair and reinstall Windows






12. 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.






13. Standard computer case form factor for modern computers.






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






15. 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






16. 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?






17. 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.






18. 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.






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






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






21. 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.






22. 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






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






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






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






26. A drive that uses both solid state and magnetic technologies.






27. 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.






28. Network with each computer






29. 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.






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






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






32. 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.






33. 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






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






35. This is how the BIOS communicates errors during POST






36. 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.






37. 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.






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






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






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






41. 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






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






43. Also known as redundant array of independent disks: Technology uses an array of hard drives used to provide fault tolerance and/or improvement in performance.






44. 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.






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






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






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






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






49. 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.






50. 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.
