Evolution of internet and web authorization.

EVOLUTION OF INTERNET:

• The origins of the Internet date back nearly 40 years, with the U.S. military's funding of a research network dubbed Arpanet in 1969.
•  Since then, the Internet has undergone more than just a name change. The number of computers connected to the Internet has grown exponentially, while the number of users has risen from a handful of computer scientists to 1.5 billion consumers.
•  The network's reach has expanded beyond the United States to every corner of the globe.

EVOLUTION OF WEB AUTHORIZATION:

• Authorization is the process of giving someone permission to do or have something.
•  In multi-user computer systems, a system administrator defines for the system which users are allowed access to the system and what privileges of use . 
• Assuming that someone has logged in to a computer operating system or application, the system or application may want to identify what resources the user can be given during this session.
•  Thus, authorization is sometimes seen as both the preliminary setting up of permissions by a system administrator and the actual checking of the permission values that have been set up when a user is getting access
