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. Comprises computing devices - softeare - or peripherals that use techniques - parts - and methods from an earlier time that are no longer popular.






2. A condition of excessive paging in which the operating system becomes sluggish.






3. The actual speed of data transfer that is achieved. It is usually less than the data transfer rate and is measured in megabits per second (Mbps).






4. A mouse that uses an internal sensor or a laser to conrtol the mouse's movement. The sensor sends signals to the computer - telling it where to move the pointer on the screen.






5. A program that takes out redundancies in a file to reduce the file size.






6. 'In a wireless network - a device that translates the electronic data that needs to be sent along the network into radio waves and then broadcasts these radio waves to other network nodes.'






7. Data that has been organized or presented in a meaningful fashion.






8. Eight binary digits(bits)






9. A network configuration in which the computers and peripherals are laid out in a configuration resembling a circle. Data flows around the circle from device to device in one direction only.






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






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






12. 'A process that involves examining incoming data packets to ensure they originated from - or are authorized by - valid users on the internal network.'






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






14. 'A single-user - single-task operating system created by Microsoft. MS-DOS was the first widely installed operating system in personal computers.'






15. 'An operating system by Microsoft that incorporates a user-friendly - graphical interface.'






16. 'A device for transmitting data on a network. A switch makes decisions - based on the media access control (MAC) address of the data - as to where the data is to be sent.'






17. A program that is hosted on a Web site and does not require installation on the computer.






18. 'A program with a specific purpose that must guarantee certain response times for particular computing tasks - or else the machine's application is useless. Real-time operating systems are found in many types of robotic equipment.'






19. An expansion card that provides the computer with a connection to the internet via conventional phone lines.






20. A heavily secured server located on a special perimeter network between a company's secure internal network and its firewall.






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






22. 'An application program - such as Microsoft Project - that helps project managers generate charts and tables used to manage aspects of a project.'






23. Any of the main files of an operating system.






24. 'An open source operating system based on UNIX. Because of the stable nature of this operating system - it is often used on Web servers.'






25. 'A physical address - similar to a serial number on an appliance - that is assigned to each network adapter; it is made up of six 2-digit characters such as 01:40:87:44:79:A5.'






26. Numbers - words - pictures - or sounds that represent facts - figures - or ideas.






27. 'Permanent storage - as in read-only memory (ROM).'






28. A common output device that creates tangible or hard copies of text and graphics.






29. A measure of processing speed equal to 1 million hertz.






30. Part of the operating system that enables individuals to interact with the computer.






31. Software that is developed for and customized to a specific industry's needs (such as a wood inventory system for a sawmill) as opposed to software that is useful across a range of industries (such as word processing software).






32. The width-to-height proportion of a monitor.






33. The process of connecting to a wireless network without the permission of the owner of the network.






34. An application program such as Microsoft Excel or Lotus 1-2-3 that enables a user to do calculations and numerical analyses easily.






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






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






37. The maximum speed at which data can be transmitted between two nodes on a network; usually measured in megabits per second (Mbps). See also data transfer rate.






38. 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.






39. 'Someone who has training in computer and peripheral maintenance and repair - network design - and the installation of network software; installs new equipment - configures computers for users - repairs equipment - and assigns network access to users






40. Temporary storage - such as in random access memory (RAM) - When the power is off - the data in volatile storage is cleared out.






41. A mini-application developed for the Macintosh platform.






42. 'A wireless standard established in 1997 by the Institute of Electrical and Electronics Engineers; also known as WiFi (short for Wireless Fidelity) - it enables wireless network devices to work seamlessly with other networks and devices.'
