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. 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?






2. 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






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






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






5. 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.






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






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






8. 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.






9. 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.






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






11. 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.






12. 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.






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






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






15. 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?






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






17. POST means __________________.






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






19. 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






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






21. 20-pin or 24-pin internal power supply connector.






22. Another name for the primary volume.






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






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






25. The one bootable partition.






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






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






28. 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.






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






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






31. 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.






32. 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






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






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






35. Standard computer case form factor for modern computers.






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






37. 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.






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






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






40. 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






41. 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.






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






43. 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.






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






45. 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.






46. 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.






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






48. Speed at which bits are transmitted - usually expressed in bits per second (bps).






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






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