WEEK 2
Navigating the Web

Part 1 - Navigation
1) Listen to the podcast on Navigation which can be found on the Digital Enterprise Page (Google - the digital enterprise).
a) What are the four (4) main points Michael Rappa makes about search? Please write them on your blog page
a search engine is essentially four things. It’s a database. It’s a collection mechanism for adding data into that database. It’s a search protocol that enables users to query the database. And it’s a ranking algorithm that determines how the results are presented to the user. And when we look at the various search engines that are out there, they vary on one or more of these dimensions. This is what a search engine is all about. (Michael Rappa)

b) Watch or read the Marissa Mayer interview. Write a paragraph or two, on four points made by Marissa Mayer, that you think were the most interesting or significant for business. There are no right or wrong answers here, I just want your opinion.
-social networking is not very popular in the United States, really popular in a couple of other countries like Brazil and India.
-now there’s a trillion URLs out there that they've seen
-A lot of people argue that Yahoo! lost its place because it lost its emphasis on engineering and technology and focused too much on marketing.
-The physical world’s been around a lot longer and so it has gotten more of the bugs and kinks out of it, where as the virtual world has alot of catching up to do.


Part 2 - History of the Internet
2) Please watch the Bill Joy video, and it will give you a good background to the Internet and particularly to the emergence of the World WIde Web.
a) so what are the 6 webs?
1-here
2-near
3-far
4-weird
5-machine to machine
6-server to server

b) Could there be more?
Yes, there are clearly two more that are essentially invisible machine to machine, and server to server known as enterprise computing.
others could be peer to peer and device to device which would be the whole realm of embedded systems.

c) What does this mean for business?
The realm of Enterprise JavaBeans and .NET and all that for businesses to remove friction from the global economy by using weblike and Internet-based things to connect things
All six of these webs essentially become interconnected pools of information that can be hyperlinked, but they are mostly "internetted" and have very different business characteristics. So we had this model, this roadmap, for how we thought this was going to develop a dozen years ago, and we used it to drive the Java strategy." (Bill Joy)
