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. 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.






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






3. 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.






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






5. A________________CD can be used to boot a system and repair or reinstall Windows.






6. 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.






7. POST means __________________.






8. A___________________can be used to test a USB port.






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






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






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






12. 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:






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






14. 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






15. 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.






16. 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






17. 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?






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






19. The one bootable partition.






20. 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






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






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






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






24. Network with each computer






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






26. 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?






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






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






29. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






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






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






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






33. 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.






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






35. 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.






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






37. 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.






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






39. 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.






40. 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.






41. 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






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






43. 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.






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






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






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






47. Standard computer case form factor for modern computers.






48. Temporary drop in AC power.






49. 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.






50. 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.
