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






2. 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.






3. __________________cards report computer errors and conflicts at POST.






4. 20-pin or 24-pin internal power supply connector.






5. 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.






6. Windows Vista technology that supports a hybrid drive.






7. 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.






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






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






10. 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.






11. Another name for the primary volume.






12. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






13. Temporary drop in AC power.






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






15. 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.






16. 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.






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






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






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






20. 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






21. 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.






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. 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.






24. Network with each computer






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. To power up a computer from the off position.






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






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






29. A self-monitoring technology whereby the BIOS monitors the health of the hard drive and warns of an impending failure.






30. 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.






31. 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.






32. 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.






33. Discovers the local address (MAC address) of a station on the network when the IP address is known. End stations as well as routers use ARP to discover local addresses:






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






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






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






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






38. 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.






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






40. 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






41. 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.






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






43. 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.






44. Used to repair and reinstall Windows






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






46. 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?






47. 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?






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






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






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