What does that make it incorrect? Or irrelevant? Computers don't really do anything but addition and conditional jump, but it's convenient to abstract them into things like relational databases and high-level languages. Could a model be developed that more closely aligns with TCP/IP? Sure. But it would likely be less useful for looking at other things, then. OSI was a failure as an actual network stack, but it makes a fair teaching tool. Kind of like the frictionless surfaces and point masses and spherical cows they use in Physics 101. They're completely impractical when they're not actually impossible, but they're convenient when thinking about a problem. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
