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






2. Another name for the primary volume.






3. 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.






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






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






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






7. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






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






9. The one bootable partition.






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






11. A___________________can be used to test a USB port.






12. 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?






13. POST means __________________.






14. 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






15. 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.






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






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






19. 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.






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






21. Method for encrypting data on a network. Uses a private key for writing messages and a public key to decode the messages. Only the private key needs to be kept secret. Public keys can be distributed openly.






22. 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.






23. 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.






24. 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.






25. 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.






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






27. 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.






28. 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.






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






30. 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.






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






32. An interface standard - part of the IDE/ATA standards - that allows tape drives - CD-ROM drives - and other drives to be treated like an IDE hard drive by the system.






33. 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.






34. 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






35. 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.






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






37. Windows Vista technology that supports a hybrid drive.






38. 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.






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






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






41. Memory that does not lose its data when the power is turned off.






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






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






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






45. 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






46. 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






47. Used to repair and reinstall Windows






48. 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






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






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.
