Created with Fabric.js 1.4.5 History of internet Defense Advance Research Project DARPA NPL RAND CYCLADES ARPANET National physical laboratory, the base of a commercialnetwork created in England RAND corporationcreated a military network in America trying to accelerate knowledge transfer they create s computer network with large scale scientific network created in France NCPWas developed for the 1st connections between computers, it was replaces by the TCP which verificated the file transfer. IMPWorked as an interface for the mainframe, itstarted programs and was in charge of data files. Meanwhile, American aircraft discovered missiles in Cuba able to reach the US. In 1962 information systems had Centralized Network Architecture, to avoid the breakdown during an attack they created a Decentralized Network so the network would be still operative. Packet SwitchingCreated to avoid congestion, where the sent files were divided into smaller packets and were put together again at the receiver. Communication worked through radio waves, in case of an atomic they wouldn't work so the Distributed Network was created so long distances could be covered with a minimum interference. X.25 Protocol was developedby the phone companies,they enabled communication in exchange of money. The TCP connected computers through gateways. The communication with other networks was developed as INTER-NET. During communication computers didn't intervene anymore,just serve as a transfer node. The International Organizationfor Standardization designedthe OSI Reference Model, an attempt to standardize thenetwork. It allowed the TCP/IPProtocol, a standard that guaranteed compability between networks and merged them creating Internet. 1990The ARPANET hardwarewas removed but the Internetkept running. To communicationthrough all machinesusing a physical layerthat was implementedinto the hardwareproviding a directconnection with thereceiver; Standardisizingthe network form itsends and the channel'sdivision in several layers. From sharing the processing power of one computer with multiple users (Time Sharing) andinstalling the Remote Connectionso the developers could workdirectly on the computers. double click to changethis text!
