Actually all are of the same design known as the IBM Compatible Personal Computer and the Server called Computers are the same.
There are other designs historically and present, but most are unsuitable.
Then, there will be two different Operating System Designs in use which are Windows and Windows Server.
I bet there are no Linux systems anywhere in any US administration office, but thats not the problem.
The problem is that you do not use Unix for Servers and the PC version from the Barkley University named FreeBSD.
Unix is older, more stable and secure and cheaper, more customizable, can run also Windows Software, has the most comprehensive user and user rights management and system log file system while being as easy to use as Windows.
Mr Gates is actually a very good and persuasive business contract sales lawyer. Like fucking good. Lockheed guys are Amateurs in comparison.
That means you might never find out who did it, while a Unix system creates a log fie with user name, time stamp, terminal used that cannot be deleted.
At least in the worst case you would know whoms password was stolen.
...if the system is set up by good character Personal properly...
