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. 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.






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






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






4. 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?






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






6. 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.






7. 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.






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






9. 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






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






11. 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.






12. 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.






13. Another name for the primary volume.






14. A drive with one - two - or more platters - or disks that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. The top and bot






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






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






17. 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.






18. Used to repair and reinstall Windows






19. 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.






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






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






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






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






24. 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.






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






26. 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






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






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






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






30. A___________________can be used to test a USB port.






31. Network with each computer






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






33. 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.






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. 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






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






37. 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.






38. 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.






39. The overall structure an OS uses to name - store - and organize files on a drive. In it - a cluster is the smallest unit of space on a disk for storing a file and is made up of one or more sectors. A it tracks how these clusters are used for each fil






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






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






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






43. 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.






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






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






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






48. 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.






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






50. 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.
