Collaborative Technologies

I'm now almost at the end of my 7th semester. I'm reviewing the title of my thesis " ...Knowledge Management Technologies ...". How does KMT compare to "Collaborative Technologies" (CT)." I simply describe KMT as technologies that facilitate KM processes (reference?). Now I'm looking at the definition of CT to be compared to CT.
The Wikipedia give a description of CT as, "Collaborative software (also referred to as groupware or workgroup support systems) is software designed to help people involved in a common task achieve their goals. Collaborative software is the basis for computer supported cooperative work."
