Subject : it-skills
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. 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.






2. 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.






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






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






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






6. 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.






7. 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.






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






9. 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.






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






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






12. 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.






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






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






15. Network with each computer






16. 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.






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






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






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






20. A___________________can be used to test a USB port.






21. 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.






22. POST means __________________.






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






24. 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.






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






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






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






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






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






30. Temporary drop in AC power.






31. 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.






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






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






34. 20-pin or 24-pin internal power supply connector.






35. 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






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. 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






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






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.






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






42. 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.






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






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






45. 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






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






47. 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






48. This is how the BIOS communicates errors during POST
