Subjects : it-skills, literacy
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. Software that provides street maps and written directions to locations.






2. A special shelf inside a computer case that is designed to hold storage devices.






3. A pen-shaped device used to tap or write on tough-sensitive screens.






4. A hardware device that uses lasers or light to read from - and maybe even write to - CDs - DVDs - or Blu-ray discs.






5. 'A method of data collision detection in which a node connected to the network listens (that is - has carrier sense) to determine that no other nodes are currently transmitting data signals; short for Carrier Sense Multiple Access with Collision Dete






6. 'A special signal sent to all network nodes - alerting them that a data collision has occurred.'






7. A wide area network (WAN) that links users in a specific geographic area (such as within a city or county).






8. 'In Windows 7 - a folder that is used to display files from different locations as if they were all saved in a single folder - regardless of where they are actually stored in the file hierarchy.'






9. A series of instructions to be followed by a computer to accomplish a task.






10. A device that routes packets of data between two or more networks.






11. A device that amplifies your wireless signal to get it out to parts of your home that are experiencing poor connectivity.






12. One billion hertz






13. A network used to connect wireless devices (such as Bluetooth-enabled devices) in close proximity to each other.






14. Manipulating or organizing data into information.






15. A drive that uses the same kind if memory that flash drives use - but can reach data in only a tenth of the time a flash drive requires.






16. The language computers use to process data into information - consisting of only the values 0 and 1.






17. 'The process of identifying a computer user - based on a login or username and password. The computer system determines whether the computer user is authorized and what level of access is to be granted on the network.'






18. The application of computer systems and techniques to gather potential legal evidence; a law enforcement specialty used to fight high-tech crime.






19. Cables made of copper wires that are twisted around each other and are surrounded by a plastic jacket (such as traditional home phone wire).






20. A self-regulatory body established in 1994 by the Entertainment Software Association that rates computer and video games according to the age appropriateness of content.






21. A nonimpact printer known for quick and quiet production and high quality printouts.






22. 'A complete processing section from a CPU - embedded into one physical chip.'






23. The most popular transmission media option for Ethernet networks. UTP cable is composed of four pairs of wires that are twisted around each other to reduce electrical interference.






24. A UTP cable type that provides more than 1 GB of throughput.






25. A printer that sprays ink or uses laser beams to make marks on the paper. The most common nonimpact printers are inkjet and laser printers.






26. A wide area network (WAN) that links users in a specific geographic area (such as within a city or county).






27. A set of memory chips - located on the motherboard - which stores data and instructions that cannot be changed or erased; it holds all the instructions the computer needs to start up.






28. A computing device that runs a full-featured operating system but weighs two punds or less.






29. Portable - nonvolatile memory.






30. A specially designed computer that can perform comples calculations extremely rapidly; used in situations in which complex models requiring intensive mathmatical calcualtions are needed (such as weather forecasting or atomic energy research).






31. 'A small program that performs many of the general housekeeping tasks for the computer - such as system maintenance and file compression.'






32. Documentation for a software product that is built directly into the software.






33. See local bus.






34. Twisted pair cable that contains a layer of foil shielding to reduce interference.






35. Programs designed to provide users with entertainment. Computer games make up the vast majority of entertainment software.






36. 'A group of two or more computers (or nodes) that are configured to share information and resources such as printers - files - and databases.'






37. 'A specialized logic chip that is dedicated to quickly displaying and calculating visual data such as shadows - textures - and luminosity.'






38. The process of starting a computer from a powered-down or off state.






39. A measurement used in comparing software and hardware performance. Benchmarks are created using software applications that are specifically designed to push the limits of computer performance.






40. 'A 3D modeling program used to create automated designs - technical drawings - and model visualizations.'






41. 'A method of optical storage for digital data - developed for storing high-definition media. It has the largest storage capacity of all optical storage options.'






42. A digit that corresponds to the on and off states of a computer's switches. A bit contains a value of either 0 or 1.






43. A special data packet that allows Data to flows from device to device in one direction only.






44. A special diagnostic mode designed for troubleshooting errors that occur during the boot process.






45. A specialized computing device designed to store and manage network data.






46. 'On the desktop - the bar that appears at the side or bottom of the window and controls which part of the information is displayed on the screen.'






47. The process of swapping data or instructions that have been placed in the swap file for later use back into active random access memory (RAM). The contents of the hard drive's swap file then become less active data or instructions.






48. When two computers send data at the same time and the sets of data collide somewhere in the media.






49. The science of using nanostructures to build devices on an extremely small scale.






50. 'A device that enables the computer (or peripheral) to communicate with the network using a common data communication language - or protocol.'
