While IT professions are very interesting, they’re usually one of the hardest to explain (in your face, quantum physics!).
Questions such as “what is ‘routing’ ?", “how do you write programs ?", “Why do we need IPv6 ?", “What’s a database ?", “What is hosting?", “what do you do at work ?” … are all easy to ask – but hard to answer to someone with little or no prior knowledge.
With that in mind, I’ll try to form an answer that most novices can understand, in an attempt to explain some of the most commonly asked IT questions. From simple subjects (such as the ones posted above), to more detailed topics like “deep packet inspection” and “virtualization”.
The first try-out will be: What is port-forwarding or routing?
