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






2. 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






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






4. A___________________can be used to test a USB port.






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






6. __________________cards report computer errors and conflicts at POST.






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






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






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. 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






11. 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.






12. 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.






13. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






14. 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.






15. 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






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






17. 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.






18. Standard computer case form factor for modern computers.






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






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






21. The one bootable partition.






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






23. 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.






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






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






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






27. 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.






28. 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






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






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






31. This is how the BIOS communicates errors during POST






32. 20-pin or 24-pin internal power supply connector.






33. 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.






34. 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.






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






36. 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.






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






38. Commonly called the host adapter. The host adapter is inserted into an expansion slot on the motherboard and is responsible for managing all devices on the SCSI bus. A host adapter can support both internal and external SCSI devices - using one conne






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






40. A standard for managing the interface between secondary storage devices and a computer system. A system can support up to six serial ATA and parallel ATA IDE devices or up to four parallel ATA IDE devices such as hard drives - CD-ROM drives - and DVD






41. 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?






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






43. 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






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






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






46. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






48. 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.






49. Most often called a hard drive - comes in two sizes for personal computers: the 2.5" size is used for laptop computers and the 3.5" size is used for desktops. In addition - a smaller 1.8" size (about the size of a credit card) hard drive is used in s






50. 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.
