You must know "Moore's Theorem", which is the most basic law of the industry for many IT people, however, in my opinion, another "Metcalfe's Law" with the same name as Moore's Theorem is seriously underestimated. Unlike Moore's Theorem, which points out the evolutionary logic of hardware performance, "Metcalfe's Law" provides a special database high-level summary of the development laws of the Internet era at the business level. This abstract summary will continue to guide the development of the Internet in the past, present and future. direction.
Metcalfe's Law" that Internet people must understand 1. What is "Metcalfe's Law" The expression of "Metcalfe's Law" is very simple - the value of a network is proportional to the square of the number of nodes in the network, and the formula is: V=K×N², where V represents the value of a network, and N represents the network The number of nodes, K represents the value coefficient. So, why is this seemingly extremely simple formula so highly special database respected by Internet people? Before answering this question, let's take a brief look at the "strange man" Metcalf: Robert Metcalf was born in Brooklyn, New York in 1946.
When he was young, Metcalf was a standard scholar. After graduating from Polytechnic with a double major in engineering and management, then a Ph.D. at Harvard, he quickly joined then-tech giant Xerox. During his time at Xerox, he invented one of the most widely used protocols for local area networks today, Ethernet, which made him a "computer special database pioneer" at a young age. "Metcalfe's Law" that Internet people must understand Ethernet sketch by Metcalfe in 1973 However, the young Metcalf did not rest on the achievements, but decided to turn the technology he mastered into commercial products at the age of 33.
