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






2. Another name for the primary volume.






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






4. 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.






5. 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?






6. 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






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






8. 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






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






10. 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.






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






12. 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.






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






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






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






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






17. 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.






18. 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?






19. 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.






20. 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






21. Standard computer case form factor for modern computers.






22. 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.






23. 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






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






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






26. 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.






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






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






29. 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.






30. Network with each computer






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






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






33. 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.






34. 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.






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






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






37. 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.






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






39. Temporary drop in AC power.






40. A___________________can be used to test a USB port.






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






42. 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






43. 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.






44. POST means __________________.






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






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






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






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






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






50. High-speed - 32-bit bus technology designed to support the acceleration of 3D computer graphics.
