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 process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






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






3. 20-pin or 24-pin internal power supply connector.






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






5. Generally the label for the first hard drive in a computer system. Drive A and Drive B are reserved for floppy drives. Drive B is rarely used on current computers.






6. 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.






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






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






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






10. 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.






11. 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.






12. 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






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






14. 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






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






17. 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.






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






19. Network with each computer






20. 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.






21. 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.






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






23. Another name for the primary volume.






24. Protocol suite to network Macintosh computers. It is comprised of a comprehensive set of protocols that span the seven layers of the OSI reference model.






25. Standard computer case form factor for modern computers.






26. 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






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






28. 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






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






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






31. 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.






32. 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.






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






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






36. A___________________can be used to test a USB port.






37. Windows Vista technology that supports a hybrid drive.






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






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






40. 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.






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






42. 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.






43. 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.






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






45. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






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






48. 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.






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






50. 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
