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






2. 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.






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






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






5. You should write down or backup changes to CMOS/BIOS setup ____________________.






6. 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.






7. 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.






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






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






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






11. 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.






12. 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.






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






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






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






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






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






18. 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.






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






20. 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?






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. 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






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






24. 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.






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






26. Temporary drop in AC power.






27. 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.






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






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






30. 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.






31. 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:






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. Backs up user-selected files to tape. This backup does not reset the archive bit.






34. 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






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






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






37. 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.






38. 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.






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






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






41. 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






42. 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.






43. Windows Vista technology that supports a hybrid drive.






44. 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.






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






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






47. Standard computer case form factor for modern computers.






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






49. 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.






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