Spaces and Exchanges To begin with, we can clearly distinguish with this mind map, a distinction between different spaces. This is divided into 3 main categories: "exchanges", "real spaces" and "virtual spaces". These are then illustrated with examples. We will first see the distinction between real and virtual spaces and then we will study the exchanges that take place in these spaces. We can see that there are many spaces in the world that can be separated into real and virtual spaces. Indeed these spaces are numerous and can be differentiated but also marked by borders. As we can see in the real spaces, some of them are delimited (North/South, public and private, first world and third world, etc...) or present inequalities. It is therefore thanks to the exchanges that any type of space can be put in relation with the rest of the world. As far as virtual spaces are concerned, they are diverse and varied, and this is mainly done
