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






2. 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:






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






4. 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






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






6. 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.






7. Windows Vista technology that supports a hybrid drive.






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






9. POST means __________________.






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






11. Another name for the primary volume.






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






13. 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.






14. 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






15. 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.






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






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






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






19. 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.






20. 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.






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






22. 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






23. Having the ability to connect and disconnect a drive while the system is running. Also called hot-plugging.






24. 4- - 6- - or 8-pin connector that supplies extra voltage to the motherboard from the power supply.






25. 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.






26. Temporary drop in AC power.






27. To power up a computer from the off position.






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






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. This is how the BIOS communicates errors during POST






31. 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.






32. 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.






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






34. 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.






35. 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.






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






37. 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.






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






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






40. 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?






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






42. 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.






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






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






45. Network with each computer






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






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






48. 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






49. 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.






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