The importance of stone tools, circa 2.5 million years ago, is considered fundamental in the human development in the hunting hypothesis. [citation needed]Primatologist, Richard Wrangham, theorizes that the control of fire by early humans and the associated development of cooking was the spark that radically changed human evolution. [2]
This is a list of obsolete technology, superseded by newer technologies. Obsolescence is defined as the "transition from available to unavailable from the manufacturer in accordance with the original specification." [1] Newer technologies can mostly be considered as disruptive innovation. Many older technologies co-exist with newer alternatives ...
New knowledge has enabled people to create new tools, and conversely, many scientific endeavors are made possible by new technologies, for example scientific instruments which allow us to study nature in more detail than our natural senses. Since much of technology is applied science, technical history is connected to the history of science.
An example of the former was the gradual roll-out of DVD (digital video disc) as a development intended to follow on from the previous optical technology compact disc. By contrast, disruptive technologies are those where a new method replaces the previous technology and makes it redundant, for example, the replacement of horse-drawn carriages ...
Technological convergence is the tendency for technologies that were originally unrelated to become more closely integrated and even unified as they develop and advance. For example, watches, telephones, television, computers, and social media platforms began as separate and mostly unrelated technologies, but have converged in many ways into an interrelated telecommunication, media, and ...
For a classic example for understanding the fundamental difference of TDMA and CDMA, imagine a cocktail party where couples are talking to each other in a single room. The room represents the available bandwidth: TDMA: A speaker takes turns talking to a listener. The speaker talks for a short time and then stops to let another couple talk.
Technology Gap Theory is a model developed by M.V. Posner in 1961, which describes an advantage enjoyed by the country that introduces new goods in a market. [1] The country will enjoy a comparative advantage as well as a temporary state of monopoly until other countries have achieved the ability to imitate the new good.
Examples of this include cars, trains, computers, and lights. Machines allow humans to tremendously exceed the limitations of their bodies. Putting a machine on the farm, a tractor, increased food productivity at least tenfold over the technology of the plow and the horse. The third, and final stage of technological evolution is the automation ...
