To be able to talk in IT-speak, you need at least a basic understanding of the subject and a certain vocabulary of buzzwords and technical terms.
In order to clear up a few terms, this page contains a small glossary of frequently used terms in web development. The glossary takes up the most important terms and provides an understandable explanation even for people with little technical knowledge.
Surely you know the situation, you talk to one of the IT managers and leave the conversation with even more questions and an unclear understanding of certain technical terms and buzzwords.
If important terms are missing, I would be happy to receive an e-mail to glossar(at)typoniels.de.
