== Context for the creation of the ARPANET ==
==A Map of the Internet==
* USA, 1960s
Ingredients:
* Cold War
* groups
* Soviet Union launched in 1957 Sputnik - the first satellite
* several protocols - in place
* Sputnik trigger a space race between US and the Soviet Union; the US only only change to win was to invest in scientific development
* Choose 3 (per groups) services/software/apps take place on the Internet. E.g. Skype, Gmail, Mail (Mac software), MSN, Whastapp, WeTransfer, Facebook, BitTorrent, etc.
* ARPANET was created by the Advanced Research Projects Agency (ARPA) 
* place each service under the right protocol


==Aims for the ARPANET==
Protocols:
* create access to remote computers
* World Wide Web (WWW)
* allow a variety of computers to join the network and be accessed
* Voice over IP (VOIP)
* foster collaborative scientific research
* File Transfer
* withstanding communications if faced with a nuclear attack
* Email (IMAP/SMTP/POP)
* Instant messaging (IM)
==Characteristics of the ARPANET==
* Internet Relay Chat (IRC)
* Distributed network: each node connects to more than 1 other node
** destruction of a node would not interrupt communication

=The World Wide Web (WWW)=
 
==Killer App: Email==
* At first the network was not heavily used
* It was difficult to access and use the different computers on the network
* the creation of electronic mail, brought many more users to network, which were simply using it to communicate
* the network changed from a resource sharing system to '''a communication system'''.
 
==Internet: the network that connected networks==
* by 1980 several digital networks, were functioning, besides ARPANET both in US and Europe:
** USENET, BITNET, FidoNet (Bulletin Board Network), etc
* these were isolated networks, not connected interconnected. 
* the task was to connect this networks
* to the wide and integrated network was given the name Internet

A Map of the Internet

Ingredients:

  • groups
  • several protocols - in place
  • Choose 3 (per groups) services/software/apps take place on the Internet. E.g. Skype, Gmail, Mail (Mac software), MSN, Whastapp, WeTransfer, Facebook, BitTorrent, etc.
  • place each service under the right protocol

Protocols:

  • World Wide Web (WWW)
  • Voice over IP (VOIP)
  • File Transfer
  • Email (IMAP/SMTP/POP)
  • Instant messaging (IM)
  • Internet Relay Chat (IRC)


The World Wide Web (WWW)

A world wide documentation system, sometimes known as the Web, same times as WWW

Web's creation

  • conceptualized by Tim Berners-Lee at CERN
  • As response to his frustration with the difficulty to share information inside and outside CERN
    • diversity of computers with different systems
    • large number of projects and individuals
    • large amounts of information with no common system to organize and communicate this information

Web: publish and find information

Tim Berners-Lee wanted to create a system that would:

  • give access to files in different computers around the world.
  • link the files among themselves
  • facilitate the location and retrieval of information

"Suppose all the information stored in computers everywhere were linked … Suppose I could program my computer to create a space in which anything could be linked to anything. All the bits of information in every computer at CERN, and on the planet, would be available to me and anyone else. These would be a single information space". [2]

How

Tim Berners-Lee

  • devised a system that connected information through links (hypertext)
  • created a hyper text language: HTML (Hyper Text Markup Language)
  • wrote an interpreter for HTML (that transforms HTML code into visual form): a web browser [3]
  • implemented a systems of addresses - URL - that allowed files in remote computers to be called and reply by sending back a (usually) HTML file.

Result

  • The Web became a system where information was easier to find
  • users of host computers (servers) could easily decide what they said to the world, and also change it
  • users became publishers of content on the Web (not even needing access to a server in order to do it)
  • that publishing possibility and will triggered the creation of web publishing services and formats (Geocities, blogs, Tumblrs, Facebook walls ,etc)
  • in this context the user is not only a consumer, but also a producer of content (or publisher)
