Q:

What does the term "semantics" mean?

In computer science materials I often see the term "semantics", and I am trying to understand what this term means.
For example "This filesystem supports full-featured POSIX semantics..."
I have checked many dictionaries and looked all over Google, but cant find a definition for this word.
Thanks

A:

If you check the Wikipedia entry you will find a section for Computer Science.  Here is snippet:

In computer science, the term semantics refers to the meaning of languages, as opposed to their form (syntax)
