Some algorithms make for 'better' programs than others - that is, programs that execute in less time or require less memory. How can we quantify differences to determine which algorithms are better? No one has done more to answer this question than Don Knuth, who has been called the 'father of the analysis of algorithms.' © 1999-2012 IEEE.

The Arpanet, which was the beginning of the Internet, was born out of the Defense Advanced Research Projects Agency (DARPA), which was created in 1958. The Arpanet was built on 56,000 bits per second telephone lines. A young MIT computer scientist named Larry Roberts settled on a network design that connected these lines to small computers, called interface message processors (IMPs), which were directly attached to each host computer on the network. The novel technical approach that Roberts chose for the Arpanet was called packet switching. Bob Kahn and Vint Cerf, another scientists at MIT created a virtual network out of software that was above the hardware networks it wove together. In the mid-1980s, the National Science Foundation (NSF) undertook efforts to create a small number of supercomputer centers for use by university researchers. Although conceived as a small network, the NSFnet eventually interconnected more than 2,000 universities and colleges and a number of high tech companies.
