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






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






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






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






5. 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.






6. 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.






7. 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.






8. 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.






9. Standard computer case form factor for modern computers.






10. 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.






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






13. A preventive maintenance plan tends to evolve from a history or pattern of __________malfunctions within an organization.






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






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






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






17. 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.






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






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






20. 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






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






22. This is how the BIOS communicates errors during POST






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






24. Used to repair and reinstall Windows






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






26. 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






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






28. 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






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






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






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






32. A file system designed to provide greater security and to support more storage capacity than the FAT32 file system.






33. __________________cards report computer errors and conflicts at POST.






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






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






36. 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.






37. 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






38. 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?






39. 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.






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






41. 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.






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






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






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






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






46. 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.






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






48. 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






49. 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






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