[QUOTE="spiney, post: 262901, member: 192438"] For understanding communications between computers, as it's now done - with "data objects" - a very useful help is the old-ish OSI 7 layer model. This gives a "very broad overview" - without delving too much into the details of various proprietry formats - giving a "rough-and-ready" idea of what's happening. A good brief description may be found at: [URL]http://www.reference.com/browse/wiki/OSI_model[/URL] . (far more details are readily available, just Google for them!). "Open Systems" was a late 1980s intitiative, supported by IBM, DEC (then the world's 2nd biggest computer company!), Sun Microsystems, etc. The 7 layer model was supposed to become an international standard, just like Jpeg, Mpeg, DVB, etc. Ironically, everybody ignored it, and now we've got lots of different proprietry systems instead! Arguably, this is much better, as sticking strictly to OSI would have been too limiting and very clumsy. However, the "generic" 7 layer model is still an excellent way of understanding what's basically going on! (As I recall, Dec's VMS directly supported OSI layers 2 and 4 - I think! - but almost no other computer manufacturer provided similar functionality! The defunct OSI standard has been partially replaced, notably by IEEE ones for computer networking). PS, that "big bronze statue" thing, outside the new British Library - referred to by Saturlight above - is actually Isaac Newton, but "the version" of him portrayed by William Blake (this representing - supposedly - both arts and sciences!). [url]http://www.bl.uk/about/stpmap/piazza.html[/url] . [url]http://www.tate.org.uk/servlet/ViewWork?workid=1122&tabview=image[/url] . Interestingly, Blake's original watercolours are very tiny, the picture on last link just above isn't much smaller than the real thing! (Rolf, I didn't de-activate above links, but did avoid a direct wiki connection!). [/QUOTE]
