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. The set of techniques used in processing and retrieving information.






2. A type of technology used to transmit video signals; used on newer LCD monitors - as well as other multimedia devices such as televisions - DVD players - and projectors.






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






4. 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.






5. 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.






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






7. The amount of random access memory (RAM) that is installed in a computer.






8. The combination of a computer's operating system and processor. The two most common platform types are the PC and the Apple Macintosh.






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






10. The metal or plastic case that holds all the physical parts of the computer together - including the computer's processor (its brains) - its memory - and the many circuit boards that help the computer function.






11. Programs for editing photographs and other images.






12. See eSata.






13. Is a device that combines the functions of a printer - scanner - copier - and fax into one machine






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






15. A single point that creates the images on a computer monitor. Pixels are illuminated by an electron beam that passes rapidly back and forth across the back of the screen so that the pixels appear to glow continuously.






16. An expansion card that attaches to the motherboard inside the system unit and that enables the computer to produce sounds by providing a connection for the speakers and microphone.






17. A server that processes and delivers incoming and outgoing e-mail.






18. A specially designed computer chip that resides inside another device - such as a car. These self-contained computer devices have their own programming and typically neither recieve input from users nor interact with other systems.

25. See local bus.






26. 'A device designed to store media - share media across the network - and back up files on computers connected to a home network.'






27. 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.






28. '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.'






29. 'The process of looking at a computer's subsystems - what they do - and how they perform to determine whether the computer system has the right hardware components to do what the user ultimately wants it to do.'






30. A circuit board with specific functions that augment the computer's basic functions and provide connections to other devices; examples include sound card and video card.






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






32. '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.'






33. A large - expensive computer that supports hundreds or thousands of users simultaneously and executes many different programs at the same time.






34. A device that sends processed data and information out of a computer in the form of text - pictures (graphics) - sounds (audio) - or video.






35. A drive that plugs into a universal serial bus(USB) port on a computer and stores data digitally. Also called USB drive - jump drive - or thumb drive.






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