1. 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.






2. A type of audio processing that makes the listener experience sound as if it were coming from all directions.






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






4. An expansion card that enables a computer to produce sounds that are omnidirectional or three dimensional.






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






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






7. A concentric circle that serves as a storage area on a hard drive platter.






8. A port that is slightly larger than a standard phone jack and transfers data at speeds of up to 10 -000Mbps; used to connect a computer to a DSL or cable modem or a network.






9. 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.






10. 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.






11. Any part of the computer you can physically touch.






12. 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).






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






14. An application program for creating dynamic slide shows such as Microsoft PowerPoint or Apple Keynote.






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






16. A program for editing digital video.






17. The design of a computer network; includes both physical and logical design.






18. The science of using nanostructures to build devices on an extremely small scale.






19. The first part of the label applied to a file; it is generally the name a user assigns to the file when saving it.






20. 'Programs such as Microsoft Outlook or Lotus Organizer that strive to replace the various management tools found on a traditional desk such as a calendar - address book - notepad - and to-do lists.'

22. Pernament storage - as in read-only memory (ROM).






23. A temporary storage area on the hard drive where the operating system 'swaps out' or moves the data or instructions from random access memory (RAM) that have not recently been used. This process takes place when more RAM space is needed.






24. When the operating system processes the task assigned a higher priority before processing a task that has been assigned a lower priority.






25. A power-management mode that saves the current state of the current system to the computer's hard drive.

34. Custom software application that is owned and controlled by the company that created it.






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






36. '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.'






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






38. Software that turns an artificial environment into a realistic experience.






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






40. A topology comprised of several topologies and combined into one network.






41. 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.






42. 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.






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