IT Explained
We at Paessler use IT-related terms constantly, and we are very much aware of the “The Imposter Syndrome”
in IT when professionals continue using terminology they might not even understand themselves. But there are also plenty of new terms in the fields of OT and IoT that many people may not be familiar with, or for which there are even contrary definitions.
At Paessler, we write a lot about IT, OT, and IoT topics. That's why you can find a comprehensive overview of relevant terminology here, which we are constantly updating.
