The creation of the Web is basically what drove the need to have a way of connecting thousands of machines and develop a mechanism between these machines to share files and data in an efficient way. In other words, the Science of Distributed Operating Systems has evolved as a result of the creation of the Web and it’s exponential growth.

• OS is made to run program
  • example:
  • Mac OS - GUI
  • UNIX - text processing, shell pipe

WEB

• Web is not tied to fixed interface
  • interface is flexible
  • different type of content, text, image, video, file, dynamic, static, are presented different way
  • website have one to many viewers.

• stateless
  • allows scalability
  • server does not keep state of client
  • the disadvantage of stateful server is the cost of coordination between servers for state of clients
