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






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






3. POST means __________________.






4. 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.






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






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






7. Standard computer case form factor for modern computers.






8. 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






9. Another name for the primary volume.






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






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






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






13. 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.






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






15. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






16. 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.






17. 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






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






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






20. This is how the BIOS communicates errors during POST






21. Temporary drop in AC power.






22. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






23. Network with each computer






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






25. 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.






26. 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.






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






28. A nonprofit organization dedicated to creating trade and communications standards.






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






30. 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?






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






32. 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.






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






34. 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.






35. 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






36. 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.






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






38. 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.






39. 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






40. 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.






41. Hardware or software systems that can use interfaces and data from earlier versions of the system or with other systems. Also known as backward-compatible or backwards compatible.






42. 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






43. Windows Vista technology that supports a hybrid drive.






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






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






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






47. 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.






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






49. Fastener used to bundle cables inside and outside of a computer.






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