It is something along the lines of “Something virtual isn’t really there but looks as if it is. Something transparent is really there but looks as if it isn’t.” That is of course the computer science sense of transparency as making the work of software invisible a user or process – for example how the network stack shields applications from whatever network media the data is travelling over to present the illusion of a connection.<o:p></o:p></div><div style="margin: 0in 0in 0.0001pt 0.5in; font-size: 11pt; font-family: Calibri, sans-serif;"><o:p> </o:p></div><div style="margin: 0in 0in 0.0001pt 0.5in; font-size: 11pt; font-family: Calibri, sans-serif;">Google is not helping me.
