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. Standard that specifies full SATA cabling for external disks.






2. POST means __________________.






3. Standard computer case form factor for modern computers.






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






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






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






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






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






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






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






11. 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.






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






13. 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.






14. __________________cards report computer errors and conflicts at POST.






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. 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






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






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






19. 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.






20. The one bootable partition.






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






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. 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.






24. 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.






25. 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.






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






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






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






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






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






33. Temporary drop in AC power.






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






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






36. 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






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






38. Another name for the primary volume.






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






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






41. Windows Vista technology that supports a hybrid drive.






42. 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.






43. 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.






44. Network with each computer






45. 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.






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






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






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






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






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