Today's lecture looked at search engines and some history of the Internet.
Lecture:
In July 1961, was the first paper on packet switching theory published.
I found out about different search engines, some of them are:
- Ask geeves
- All the web
- Wise nut
- Hot bot
- Altavista
The most reliable search directories with comprehensive databases are:
- Look smart
- Dmoz
- Google directory
- About
- Yahoo directory
There are three categories of information on the web:
- The free, visible web
- The free, invisible web and
- The paid databases over the web
Many problems with search engines are:
- There is too much information
- Don't know if the information is genuine/true
- Can face many problems
- Limited relevance
- Misuse of page ranking
To limit searches you could use advanced search, commas
