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. 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.






2. 'Software that handles requests for information - Internet access - and the use of peripherals for the rest of the network nodes.'






3. A small circuit board that holds a series of random access memory (RAM) chips.






4. 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).






5. How a user sets up his or her computer and other equipment to minimize risk of injury or discomfort.






6. A computer that is intended for use at a single location. A desktop computer consists of a case that houses the main components of the computer - plus peripheral devices.






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






8. 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






9. A user interface in which the user chooses a command from menus displayed on the screen.






10. A display that uses organic compounds to produce light when exposed to an electric current. Unlike LCD's - OLEDs do not require a backlight to function and therefore draw less power and have a much thinner display - sometimes as thin as 3mm.






11. A system of networking connections in which all devices are connected to a central cable called the bus (or backbone).






12. 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.






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






14. '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.'






15. 'A network topology in which each node on the network is responsible for retransmitting the token - or the data - to other nodes.'






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






17. 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.






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






19. An expansion card that is installed inside a system unit to translate binary data (the 1s and 0s the computer uses) into the images viewed on the monitor.






20. 'In later versions of Windows operating systems - a feature that displays open and favorite applications for easy access.'






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






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






23. The radio waves or cable that transport data on a network.






24. A data-processing device that gathers - processes - outputs - and stores digital data and information.






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






26. 'The portion of a company's intranet that is used to share business information with business partners such as vendors - suppliers - and customers.'






27. The time it takes a storage device to locate its stored data.






28. A folder on a Windows desktop in which deleted files from the hard drive are held until permanently purged from the system.






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






30. A cable that transmits data at close to the speed of light along glass or plastic fibers.






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






32. The discrepancy between those who have access to the oppertunities and knowledge computers and the internet offer and those who do not.






33. '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.'






34. Software that translates spoken words into typed text.






35. A special numerical code that prioritizes requests from various devices. These requests then are placed in the interrupt table in the computer's primary memory.






36. Anyone who unlawfully breaks into a computer system (whether an individual computer or a network).






37. The most commonly used wired Ethernet standard deployed in devices designed for home networks which provides bandwidth of up to 1 Gbps.






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






39. The ability to easily add more users to a network without affecting the performance of the other network nodes (computers or peripherals).






40. See eSata.






41. 'System that is used to control many 'back office' operations and processing functions such as billing - production - inventory management - and human resources management.'






42. A network in which the nodes are located within a small geographic area.






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






44. The set of computer programs or instructions that tells the computer what to do and enables it to perform different tasks.






45. A printer that works either by melting wax-based ink onto ordinary paper (in a process called thermal wax transfer printing) or by burning dots onto specially coated paper (in a process called direct thermal printing).






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






47. 'A device connected to a network such as a computer - a peripheral (such as a printer) - or a communications device (such as a modem).'






48. The process for loading the operating system (OS) into random access memory (RAM) when the computer is turned on.






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






50. A set of controls on standard keyboards that moves the cursor(the flashing symbol on the monitor that indicates where the next character will be inserted); also known as an arrow key.
