Informationssysteme sind

• offen
  • Sie interagieren mit der Umwelt und anderen Informationssystemen.
• dynamisch
  • Sie verändern sich im Zeitablauf, z.B. durch Lernprozesse.
• komplex
  • Sie verknüpfen eine große Anzahl unterschiedlicher Elemente.

1980er: Dave Farber of the University of Delaware reveals a project to build an inexpensive network using dial-up phone lines. In 1982, the PhoneNet system is established and is connected to ARPANET and the first commercial network, Telenet. This broadens access to the internet and allows for email communication between multiple nations of the world. In 1981, Metcalfe’s company 3Com announces Ethernet products for both computer workstations and personal computers; this allows for the establishment of local area networks (LANs). Paul Mockapetris, Jon Postel and Craig Partridge create the Domain Name system, which uses domain names to manage the increasing number of users on the internet. In 1985, the first domain is registered: symbolics.com, a domain belonging to a computer manufacturer.

Tim Berners-Lee and his colleagues at CERN develop hypertext markup language (HTML) and the uniform resource locator (URL), giving birth to the first incarnation of the World Wide Web.

In 1990, ARPANET is decommissioned.

A watershed year for the internet comes in 1995: Microsoft launches Windows 95; Amazon, Yahoo and eBay all launch; Internet Explorer launches; and Java is created, allowing for animation on websites and creating a new flurry of internet activity.

In 1996, Congress passes the Communications Decency Act in an effort to combat the growing amount of objectionable material on the internet. John Perry Barlow responds with an essay, A Declaration of the Independence of Cyberspace.

Google is founded in 1998.

In 1999, the music and video piracy controversy intensifies with the launch of Napster.

The first internet-capable virus is discovered in 1999

1973, Robert Kahn and Vinton Cerf collaborate to develop a protocol for linking multiple networks together. This later becomes the Transmission Control Protocol/Internet Protocol (TCP/IP), a technology that links multiple networks together such that, if one network is brought down, the others do not collapse

While working at Xerox, Robert Metcalfe develops a system using cables that allows for transfer of more data over a network. He names this system Alto Aloha, but it later becomes known as Ethernet

Over the next few years, Ted Nelson proposes using hypertext to organize network information, and Unix becomes popular for TCP/IP networks

Tom Truscott and Steve Bellovin develop a Unix-based system for transferring data over phone lines via a dial-up connection. This system becomes USENET.
