Laws must not forget


Moore Moore's Law states that every two years approximately doubles the number of transistors on an integrated circuit. It is an empirical law formulated by the co-founder of Intel, Gordon E. Moore on April 19, 1965, compliance with which it has been shown to date.

In 1965 Gordon Moore said that the technology had a future, that the number of transistors per inch on integrated circuits had doubled every year and that trend would continue for the next two decades.

Later, in 1975, changed its own law by stating that the rate would drop, and integration capacity will double approximately every 24 months. This progression of exponential growth, doubling the capacity of integrated circuits every two years, is what is considered Moore's Law. However, Moore himself has expiry date to their law: "My law will be fulfilled within 10 or 15 years from 2007 -". As stated in conference in which he said his prediction, however, that a new technology will come to replace the current one.

The direct consequence of Moore's Law is that prices fall while climbing performance: computer worth $ 3000 now cost half the following year and will be obsolete in two years. In 26 years the number of transistors on a chip has increased 3200 times.

is now applied to personal computers. However, when processors were not made, invented in 1971, no personal computers, popularized in the 1980's.

At the time of writing the article originated His law, Moore was director of Fairchild Semiconductor laboratories. Later in the summer of 1968, Intel created along with Robert Noyce, one of his colleagues in both companies.

Moore is wrong to say that his law would not be met within 10 or 15 years since the Israeli company has created lenslet EnLight265 processor that is 1000 times faster.

Reed Act

Reed's law is the assertion of David P. Reed says that the utility of large networks, particularly social networks, scale exponentially with the size of the network.

The reason for this is that the number of subgroups of potential network participants is 2 ^ N - N - 1 \\,, where N is the number of participants. It grows much faster than any of the two:

* the number of participants N, or
* the number of possible pairs of connections (which follow Metcalfe's Law)


Metcalfe law Metcalfe says that the value of a communications network increases proportionally to the square of the number of users of the system (n2).

first formulated by Robert Metcalfe in regard to Ethernet, Metcalfe's law explains many of the effects of network technologies and communication networks like the Internet or World Wide Web.

law usually illustrated by the example of fax machines: a single fax machine is useless, but its value increases with the total number of fax machines on the network, because it increases the number of people you can communicate. Luis Alberto Rojas Leal
