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






2. 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.






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






4. Standard that specifies full SATA cabling for external disks.






5. 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.






6. 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.






7. 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.






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






10. 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.






11. 20-pin or 24-pin internal power supply connector.






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






13. A sealed - magnetic coil device that moves across the surface of a disk either reading data from or writing data to the disk.






14. 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.






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






16. 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






17. The overall structure an OS uses to name - store - and organize files on a drive. In it - a cluster is the smallest unit of space on a disk for storing a file and is made up of one or more sectors. A it tracks how these clusters are used for each fil






18. POST means __________________.






19. Set of conductors - bundled and sheathed together - made of insulated copper or optical fiber that transport signals and power between electrical devices.






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






21. 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.






22. 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.






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






24. 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






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






26. 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.






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






28. 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






29. A drive with no moving parts. Uses nonvolatile flash memory.






30. 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.






31. 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.






32. 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.






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






34. 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






35. 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.






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






37. 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.






38. 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:






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






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






41. 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.






42. Network with each computer






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






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






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






46. 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






47. 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.






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






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






50. 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?
