1. Based on the presentation last Friday, what were the circumstances that drove the people during that time to developed technologies towards inter-networks?
Life before was hard and too many procedures on doing their works, then they decided to invent technology that helps them make their work easier thru using the internet.
2. How did the different technologies contribute to the evolution of the modern Internet?
Over the past century and a half, important technological developments have created a global environment that is drawing the people of the world closer and closer together. During the industrial revolution, we learned to put motors to work to magnify human and animal muscle power. In the new Information Age, we are learning to magnify brainpower by putting the power of computation wherever we need it, and to provide information services on a global basis. Computer resources are infinitely flexible tools; networked together, they allow us to generate, exchange, share and manipulate information in an uncountable number of ways. The Internet, as an integrating force, has melded the technology of communications and computing to provide instant connectivity and global information services to all its users at very low cost.
3. If you could change or improve something in the internet and/or its services, what would it be?
If I where to improve the internet, I would improve its security preventing hackers to hack an other computers and steal the important files. by improving this gives an individual a secured life in the internet.

When you enter a keyword or phrase into a search engine, an integrated piece of software searches the index database to retrieve the relevant data. and for the meta search engine This eliminates the need to query the major search engines separately. A metasearch engine will search all or selected search engines and aggregate the results into a single list or display them according to their source.
3.) when is it appropriate to use a search engine? when is it appropriate to use search/subject directory?
