29. A tyoe of audio processing that makes the listner experiance sound as if it were coming in all directions.






30. 'Program code made publicly available for free; it can be copied - distributed - or changed without the stringent copyright protections of proprietary software products.'






31. 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.






32. A device that allows you to capture sound waves - such as those created by your voice - and transfer them to digital format on your computer.

39. A single copper wire surrounded by layers of plastic insulation and sheathing; used mainly in cable television and cable Internet service.
