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






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






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






6. Temporary drop in AC power.






7. An older IDE cabling method that uses a 40-pin flat data cable or an 80-conductor cable and a 40-pin IDE connector.






8. 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.






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






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






11. 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.






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






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






14. 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






15. 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.






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






17. Used to repair and reinstall Windows






18. 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.






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






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






21. 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






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






23. Network with each computer






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






25. 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.






26. This is how the BIOS communicates errors during POST






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






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






29. 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:






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






31. A method of data transfer between hard drive and memory that allows multiple data transfers on a single software interrupt.






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






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






34. Windows Vista technology that supports a hybrid drive.






35. 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.






36. Another name for the primary volume.






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






38. 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.






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






40. 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.






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






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






43. 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






44. 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.






45. 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.






46. 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.






47. 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.






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






49. Operating system feature that enables a computer to assign itself an address if it is unable to contact a DHCP server. The Internet Assigned Numbers Authority (IANA) has reserved private IP addresses in the range of 169.254.0.0 -169.254.255.255 for A






50. 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.
