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. 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.






2. 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?






3. 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.






4. 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






5. 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.






6. This is how the BIOS communicates errors during POST






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






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






9. Another name for the primary volume.






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






11. 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?






12. Temporary drop in AC power.






13. 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.






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






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






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






17. 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.






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






19. 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.






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






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






22. 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






23. 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.






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






25. __________________cards report computer errors and conflicts at POST.






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






27. Windows Vista technology that supports a hybrid drive.






28. 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






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






30. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






31. 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:






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






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






34. 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.






35. 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.






36. 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






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






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






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






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






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






42. 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.






43. 20-pin or 24-pin internal power supply connector.






44. 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






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






46. 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.






47. 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






48. 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.






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






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