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






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






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






4. 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.






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






6. 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.






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






8. 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






9. The 12-bit wide - one-column file allocation table for a floppy disk - containing information about how each cluster or file allocation unit on the disk is currently used.






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






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






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






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






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






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






16. The circuit board that controls a SCSI bus supporting as many as seven or fifteen separate devices. This device controls communication between the SCSI bus and the PC.






17. Used to repair and reinstall Windows






18. 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






19. 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






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






21. 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.






22. 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.






23. 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.






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






25. 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.






26. 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.






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






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






29. 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.






30. 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.






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






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






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






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






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






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






37. 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.






38. 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






39. 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






40. Temporary drop in AC power.






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






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. 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.






45. This is how the BIOS communicates errors during POST






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






47. A set of tools - routines and protocols used to develop software applications that will be compatible with an operating system.






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






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






50. Standard computer case form factor for modern computers.
