Connection is established according to certain hierarchies. And like the logic of traditional political economy all elements conform to formal standardization. Computer networks are not a heterogeneity. Computer fonts are an indication of a type of technological complexity that allows for wide varieties of font faces, sizes, shapes, distortions, and types of mark-up. By way of illustration, allow me to compare these two elements.
Computer fonts do the same work in the digito-semiotic world that HTML does in the virtual world.
They both are a set of instructions for the compilation of contents. Fonts compile and represent digitized texts, while HTML compiles and displays hypertextual elements. On load a derivative of each element is placed. On unload that copy is discarded. However, computer fonts are not representation per se.
