I dont agree with the rant on software developers not coding for non administrative accounts. Quite rightly so the operating systems have been restricting what we can do so for some operations we have been required to ask users to login under administrative actions to perform these things. The problem actually is that the end user see's this as an irritation and rather than suffer the account changes decides to just run as administrator all the time for a simple life - which then creates the security risk. It is not something the software developer can either code for, cater for and allow for - its just human nature.
The changes in vista were to give us software developers an avenue to allow the user to temporarily go into administrative mode to perform these functions - which is not dissimilar in linux to drop into superuser etc.
I would say before laying blame on the developer - fully assess and understand the constraints they are working within.
Jofm5, I don't think you understand my rant! I am pissed at those developers - mainly of games - who release software that
cannot be used unless one is an administrator. I don't mean cannot be installed or configured, I mean will not run unless using an admin account.
I have found that the vast majority of software I have installed for my children over the last 10 years won't run unless they are running with an admin account! I mean FFS - requiring 3-12 year-olds to operate as admins!
I have usually been able to laboriously find out what part of the file system the game is trying to write to, and assign write access there for the kids' user accounts. But that is what I'm talking about - it's sloppy and it's lazy.
On a couple of factual points - a router doesn't split any networks. All it does is connect 2 or more different IP networks.
Also, I think you will find that TCP and UDP sit alongside each other in the Transport Layer, both above IP - the Network Layer. Lots of good reading on TCP/IP and IP networking to be found via google -
