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. 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.






2. 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.






3. 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






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






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






6. 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.






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






8. 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.






9. 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.






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






11. __________________cards report computer errors and conflicts at POST.






12. 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.






13. 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.






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






15. 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






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






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






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






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






20. 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.






21. 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:






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






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






24. 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.






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






26. 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






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






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






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






30. 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






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






32. 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






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






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






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






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






37. 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.






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






39. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






41. 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.






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






43. 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.






44. 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
