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.

1. Portable - nonvolatile memory.






2. An internal hard drive that is enclosed in a protective case to make it portable - the drive is connected to the computer with a data transfer cable and is often used to back up data.






3. A small - joystick-like nub that enables you to move the cursor with the tip of your finger.






4. 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.






5. A Windows utility that removes unnecessary files from the hard drive.






6. A program that manages the data between a computer's operating system and all the input and output devices attached to the computer; also responsible for loading the operating system (OS) from its permanent location on the hard drive to random access






7. 'An electronic filing system best used for larger and more complicated groups of data that require more than one table and the ability to group - sort - and retrieve data and generate reports.'






8. An active topology (meaning that data is retransmitted) in which the nodes connect to a central communications device called a switch. The switch receives a signal from the sending node and retransmits it to the node that should receive it.






9. The set of programs that enables a computer's hardware devices and application software to work together; it includes the operating system and utility programs.






10. '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.'






11. An interface through which external devices are connected to the computer.






12. A computer that provides resources to other computers on a network.






13. A type of wireless technology that uses radio waves to transmit data over short distances (approximately 30 feet for bluetooth 1 and 60 feet for bluetooth 2). Often used to connect peripherals such as printers and keyboards to computers or headsets t






14. The 802.11 standard for wireless data transmissions established by the Institute of Electrical and Electronics Engineers (IEEE).






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






16. Programs that perform basic editing tasks on audio files such as cutting dead air space from the beginning or end of a song or cutting a portion from the middle.






17. 'A section of a hard drive platter - wedge-shaped from the center of the platter to the edge.'






18. A device that holds all permanently stored programs and data; can be located inside the system unit or attached to the system unit via a USB port.






19. The process of restarting the system while it's powered on.

22. The ability of an operating system to perform more than one process at a time.






23. A nonimpact printer that sprays tiny drops of ink onto a paper.






24. A Windows utility that checks for lost files and fragments as well as physical errors on a hard drive.






25. A home that has a computer and other digital devices that are all connected to a home network.






26. A type of network that uses servers to deliver services to computers that are requesting them (clients).






27. '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.'






28. '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.'






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






30. 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).






31. 'The set of programs on a computer that helps a user carry out tasks such as word processing - sending e-mail - balancing a budget - creating presentations - editing photos - taking an online course - and playing games.'






32. A device (such as a printer or external hard drive) that can be attached directly to a network instead of needing to attach to a computer on the network.






33. Unwanted or junk e-mail






34. A low-power mode for electronic devices such as computers that saves electric poer consumption and sace your computer settings where you left off. When the computer is 'woken up -' you can resume working more quickly that when cold booting the comput






35. Software that provides street maps and written directions to locations.






36. A single software program that incorporates the most commonly used tools of many productivity software programs.






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






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






39. The set of programs that enables a computer's hardware devices and application software to work together; it includes the operating system and utility programs.






40. A signal that tells the operating system that it is in need of immediate attention.






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






42. Communications media that do not use cables but instead rely on radio waves to communicate.






43. A device similar to a switch in an Ethernet network. It takes the place of a wireless network adapter and helps relay data between network nodes.
