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. 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






2. 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.






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






4. 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.






5. Windows Vista technology that supports a hybrid drive.






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






7. 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.






8. 20-pin or 24-pin internal power supply connector.






9. 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






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






11. 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?






12. 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.






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






14. A___________________can be used to test a USB port.






15. 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.






16. 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.






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






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






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






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






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






22. 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






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






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






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






26. 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.






27. 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.






28. 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.






29. 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.






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






31. This is how the BIOS communicates errors during POST






32. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






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. Standard that specifies full SATA cabling for external disks.






35. 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:






36. 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.






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






38. Another name for the primary volume.






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






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

43. 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.






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






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






46. A Data Link layer device that connects and passes frames between two network segments. The frames are filtered and forwarded using MAC addresses.






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






48. 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.






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