What is contact scraping?

Social networking has brought about a new trend called contact scraping, where an online company with access to a person’s mail account goes through the contact list and sends out an invitation to all to join the site. Once a person enters his/her credentials, like user name or password, the company sweeps through the contact list. The company gets free publicity and widens its user base, but could put the person concerned in an embarrassing and annoying situation, especially when there are friendly mails from strangers in return.

How old is the Internet?

The Internet is 35 years old. J.C.R. Licklider of the Massachusetts of Technology first proposed a global network of computers in 1962, and moved to the Defense Advanced Research Projects Agency (DARPA) to develop it. Leonard Kleinrock developed the theory of packet switching, the basis of Internet connections. On September 2, 1969, Stephen Crocker and Vinton Cerf, two graduate students at the University of California Los Angeles (UCLA), linked two large computers using a 15-foot cable and tested a new way to exchange data. In January, three other "nodes" were added to this network. The earliest idea of a computer network intended to allow general communication between users of various computers was the ARPANET, the world's first packet switching network.
