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 drive that uses both solid state and magnetic technologies.






2. 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.






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






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






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






7. 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.






8. In Windows XP - you should choose the _______________setting for updates.






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. 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






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






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






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






14. 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.






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






16. When troubleshooting a failed boot - if you do not see any lights or hear any noises - what hardware system do you first assume is at fault?






17. 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






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






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






20. Another name for the primary volume.






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






22. 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.






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






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






25. 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.






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






27. 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.






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






29. 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






30. 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.






31. 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.






32. 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.






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






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






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






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






37. 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.






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






39. This is how the BIOS communicates errors during POST






40. 20-pin or 24-pin internal power supply connector.






41. 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.






42. 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.






43. 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.






44. 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.






45. A___________________can be used to test a USB port.






46. Used to repair and reinstall Windows






47. 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?






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






49. POST means __________________.






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