And what does the whole sentence mean?

It means what it says. It's not an obscure sentence at all. If you understood the previous pages of the text, you should have no difficulty.
Read it in context:

Dividing a graph into its components is of course only a first, global way of describing its structure. Within a given component, there may be richer internal structure that is important to one’s interpretation of the network. For example, thinking about the largest component from Figure 2.6 in light of the collaborations that it represents, one notices certain suggestive features of the structure: a prominent node at the center, and tightly-knit groups linked to this node but not to each other. One way to formalize the role of the prominent central node is to observe that the largest connected component would break apart into three distinct components if this node were removed. Analyzing a graph this way, in terms of its densely-connected regions and the boundaries between them, is a powerful way of thinking about network structure.
