Container shipping (which joins road, rail, and shipping networks) and the linkage of cellular with land-line telephony are examples of internetworks in other domains. Gateways need not be, and often are not, technological. For example, far more important than hardware in linking global financial markets into a single infrastructure were institutional, legal, and political gateways that permitted trans-border stock trading, currency exchange, and so on. No system or network can ever fulfill all the requirements users may have.

15 Technology transfer to other locations (cities or nations) follows the initial system elaboration phase. ” In the growth phase, the system spreads quickly and opportunities for both profit and innovation peak. New players may create competing systems with dissimilar, incompatible properties (for example, DC vs. AC electric power, or the Windows operating system vs. Macintosh and Linux). During consolidation, the quasi-final stage of LTS development, competition among technological systems and standards may be resolved by the victory of one over the others.

Instead of thinking about knowledge as pure facts, theories, and ideas—mental things carried around in people’s heads, or written down in textbooks—an infrastructure perspective views knowledge as an enduring, widely shared sociotechnical system. Here is a definition: Knowledge infrastructures comprise robust networks of people, artifacts, and institutions that generate, share, and maintain specific knowledge about the human and natural worlds. 24 If you want to be a scientist, you probably are going to need some technological items, such as instruments and computers.
