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. 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.






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






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






5. 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.






6. Temporary drop in AC power.






7. 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.






8. 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.






9. This is how the BIOS communicates errors during POST






10. 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.






11. Physical connection between an interface processor or card - the data buses - and the power distribution buses inside a chassis.






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






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






14. 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.






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






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. 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






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






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






20. Windows Vista technology that supports a hybrid drive.






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






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






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






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






25. 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






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






27. Standard computer case form factor for modern computers.






28. 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.






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






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






31. 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.






32. 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.






33. 20-pin or 24-pin internal power supply connector.






34. 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.






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






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






37. 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.






38. POST means __________________.






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






40. __________________cards report computer errors and conflicts at POST.






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






42. 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.






43. 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






44. 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:






45. A feature of system BIOS and hard drives that automatically identifies and configures a new drive in CMOS setup.






46. 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.






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






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






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






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