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
