This web page looks at some of the terminology associated with the Computer Industry. This appendix is not to be deemed as complete but does cover a large range of common terminology.
If you find a term not covered in this file you may and list the word (computer connected terminology ONLY). We will endeavour to locate the meaning and respond to you. If we consider it a common enough term, we will add it to our list. New terminology (with explanation) may also be submitted for consideration.
For a more comprehensive terminolgy site, look at WHATIS.COM. This will open in a new window. Just close that window to return here.
