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. 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






3. 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.






4. 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.






5. 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






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






7. 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






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






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






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






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






12. 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.






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






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






15. 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.






16. This is how the BIOS communicates errors during POST






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






19. This tool can be used to test a USB port.






20. __________________cards report computer errors and conflicts at POST.






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






22. 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






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






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






25. Standard computer case form factor for modern computers.






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






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






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






29. 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.






30. 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






31. The process - you specify the size of the partition and what file system it will use.






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






33. 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.






34. A number assigned to a logical device (such as a tray in a CD changer) that is part of a physical SCSI device - which is assigned a SCSI ID.






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






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






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






38. Windows Vista technology that supports a hybrid drive.






39. 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






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






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






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






43. A___________________can be used to test a USB port.






44. 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






45. 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.






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






47. 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.






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






49. 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.






50. 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?
