IT stands for "Information Technology", and it is more or less the compilation of all the technologies that maipulate data that we, humans, have used or created. Commonly, it is used as a business-related term.
Then ICT stands for "Information and Communications Technology", and it encompasses all the recently developed products that are also part of IT, only now classified as a new, completely evolved part.
They help us be more creative and innovative, but they also help in creating processes, being utterly necessary in this day and age for our lifestyle to survive. These new and not so new technologies are vital, they come in handy in many daily situations, and as dependant as we are now to them, we can barely exist without them.
