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. 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.






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






3. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






5. 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.






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






7. 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.






8. 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






9. 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.






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






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






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






13. 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.






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






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






16. 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






17. Issues dial - hang up - reset - and other instructions to the modem. It is based on the Hayes command set.






18. 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.






19. 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.






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






22. 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.






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






24. 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.






25. Standard computer case form factor for modern computers.






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






27. 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.






28. The one bootable partition.






29. 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.






30. Windows Vista technology that supports a hybrid drive.






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






32. POST means __________________.






33. A___________________can be used to test a USB port.






34. 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






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






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






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






38. 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.






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






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






41. 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.






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






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






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






45. This is how the BIOS communicates errors during POST






46. Temporary drop in AC power.






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






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






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






50. 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.
