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






2. 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.






3. 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.






4. 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.






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






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






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






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






11. 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.






12. Network with each computer






13. 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






14. This is how the BIOS communicates errors during POST






15. 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.






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






17. 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.






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. 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.






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






21. 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.






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






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






24. 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






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. A___________________can be used to test a USB port.






27. A drive with no moving parts. Uses nonvolatile flash memory.






28. 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.






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






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






31. 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






32. 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.






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






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






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






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






37. Used to repair and reinstall Windows






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






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






40. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






41. 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.






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






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






44. Another name for the primary volume.






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






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. 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






48. 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.






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






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