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






2. Being familiar enough with computers that you understand their capabilities and limitations and know how to use them.






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






4. One billion hertz






5. A collection of software programs that have been bundled together as a package.






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






7. 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.






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






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






10. A power supply regulates the wall voltage to the voltages required by computer chips; it is housed inside the system unit.






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






12. A computer running a specialized operating system that enables it to host Web pages (and other information) and provide requested Web pages to clients.






13. 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.






14. 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






15. See local bus.






16. 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.






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






18. '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.'






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






20. A group of icons collected for easy access.






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






22. A computer-controlled mannequin that simulates human body functions and reactions.Patient simulators are used in training doctors - nurses - and emergency services personnel by simulating dangerous situations that would put live patients at risk.






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






24. A special circuit board in the system unit that contains the central processeing unit (CPU) - the memory (RAM) chips - and the slots available for expansion cards; all of the other boards (video cards - sound cards - and so on) connect to it to recie






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






26. 'Programs for managing finances - such as Intuit's Quicken and Microsoft Money - which include electronic checkbook registers and automatic bill payment tools.'






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

29. That status of software(or other created works) that are not protected by copyright.






30. 'A thin - round - metallic storage plate stacked onto the hard drive spindle.'






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






32. A network that uses public communication pathways (usually the Internet) to provide branch offices or employees who are not at the office with secure access to the company network. VPNs maintain privacy by using secure data communication protocols.






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






34. A hardware device used to enter user responses and commands into a computer.






35. '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.'






36. '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.'






37. 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.






38. Acts as a go-between for computers on the internal network and the external network (the Internet).

43. 'A prediction - named after Gordon Moore - the cofounder of Intel; states that the number of transistors on a CPU chip will double every two years.'


44. 'Software - often used for training purposes - which allows the user to experience or control an event as if it is reality.'






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