3. The Evolution of Networking Technologies

Over time, technology changes and, usually, advances. Advancements in this context generally refer to being able to do more transactions with more people for more profit. Of course, generalizations of this sort tend to be true on the macroscopic level only as the tiny deltas in capabilities, offerings, and the vagaries of markets drive many small changes, some of which are detrimental. However, over the long term and at the macroscopic level, advances in technology enable us to do more things with more people more easily and in closer to real time.

There are more than a few laws that track the evolution of some distinct technology trends and the positive effects that are expected. A good example of this is Moore’s Law, which has yet to be disproven and has proven true since the 1960s. Moore’s Law,[4] put simply, postulates that the number of transistors that can be effectively integrated doubles roughly every two years, and the resultant computing power or efficiency increases along with that. Most of us in technology know Moore’s Law, and it is arguable that we as a society depend on it for economic growth and stimulus: There is always more demand for more computing power (or has been to date and for the foreseeable future). A less known further example is Gilder’s Law[5] (which has since been disproven) that asserts that a similar, related growth in available bandwidth occurs over time.
