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






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






3. 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.






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






5. 20-pin or 24-pin internal power supply connector.






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






7. Used to repair and reinstall Windows






8. 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






9. 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






10. 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






11. 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.






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. 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.






14. 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?






15. 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.






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






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






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






19. 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.






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






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






22. 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.






23. __________________cards report computer errors and conflicts at POST.






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






25. Temporary drop in AC power.






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






27. 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.






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






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






31. Five possible questions that should be asked of a user who is experiencing computer problems: What had just happened? What recent changes did the user make? When did the computer __________? What error message do you see?






32. 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






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






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






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






36. 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






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






38. A________________CD can be used to boot a system and repair or reinstall Windows.






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






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






41. POST means __________________.






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






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






45. 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






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






47. This is how the BIOS communicates errors during POST






48. A process (usually performed at the factory) that electronically creates the hard drive tracks and sectors and tests for bad spots on the disk surface.






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






50. 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.
