• DARPA– information was
manually transferred by human
– a plan was developed to eliminate the manual processing

History of the Internet
• In 1966, ARPANET was developed
• It was then utilized by the Universities
• to share information the Mainframe was introduced

History of the Internet
• Mainframe uses an Interface Messaging Processor (IMP)
• IMP is the global control of the activity while the mainframe is only the initialization of the programs and data files
• It is also the interface for the mainframe
