Genesis and History of The Internet and the WWW

• USSR - SPUTNIK in 1958

• DARPA – TCP/IP – VINTON CERF (1969)

• INTER NETWORK

• WWW – HTTP / HTML – The Great ‘Tim Berners-Lee’

• Vannevar Bush’s ‘as we may think’ (1945)

As We May Think…

The Idea!

• Consolidating human knowledge and know-how

• Integrating Knowledge as chains – Hyper Links - Memex (Memory and Index)

• Word Hyper came from the word ‘Hyper Space’

• Hyperlinking of the information stored in the human brain analogy for linking the information stored in the machines (computers) too

The Evolution

Web 4.0

"Good morning. You're flying to Boston today. Take a raincoat, it's raining. By the way, that fight you were taking, it’s already been cancelled. Don't worry about it. There was a mechanical. I've already booked you on a new one. I'll tell you about on the way to the airport. But remember you’re going to exercise every day and I’m here to remind you that you’re going to exercise.”

Key Issues

Net Neutrality

Standardisation Issues

Security and Privacy

Net Neutrality • Service should be available to anyone who wishes to use it regardless of

who they are and what they can afford to pay

Policies of the Governments

• Google, Facebook, Twitter are banned in China

• Indian Govt. Yet to make a strong stand on this issue

• Gender Determination Advertisements are banned in India

• Whatsapp Messages, Defining Cybercrime

Security and Privacy

• Loss of Information (from web servers and phones)

• London Riots

• Visa Denial based on Social Media Usage Pattern

• CIBIL Rating

• Activities of USA’s NSA

• Edward Snowden

Web belong to all of us!

Points to Ponder

• Gov. / Technology Companies / Agencies have to create policies for ensuring privacy

• Gov. should entertain constructive usage of technology

• Strong cyber laws to protect people

• Ethical / Personal change is the need of the hour

How to keep myself safe? Pay cash for everything! Never go online! Don’t use a mobile phone! Never leave your house!
