Transistors were first developed in 1947 by Bell Laboratories and allow precise control of the flow of current through circuit boards. A transistor is the active component in almost all modern electronics systems. Moore’s law predicted that over the history of computing hardware the amount of transistors in integrated circuits will double every two years, influencing their impact on the evolution of technology.

The first message was sent electronically between two computers was sent over the ARPANET in 1969. The World Wide Web as we know it with its linked hypertext documents was proposed in March 1989 by Tim Berners-Lee, a British computer scientist.
Berners-Lee and Robert Cailliau proposed the links to a web of nodes in 1990 – the year that the first web site was completed.

3D Printing technology
Creating a three dimensional solid object digitally is something that the automotive and aerospace industry has been using since the 1980s. Printers have become widely available recently and are used to print anything from teapots to guns.
You can even buy your own 3D printer from Staples for $1299.
