Assignment 3 - After reading Chapter 3 and 4, post to your blog 3 facts you learned from each chapter. Tell the fact, definition, or explain what you learned.
Chapter 3
Fact 1 - I learned that a printer-friendly version of a message excludes content, such as ads and links.
Fact 2 - I learned that Windows Live provides free Web-based services to account holders to allow file and photo sharing. Windows Live also presents an opportunity to manage an online profile to create a network of friends.
Fact 3 - I learned that Gmail is made free to users by adding advertisements to email messages in the form of targeted advertisements. Targeted advertisements are added to the user's message based on keywords included in the message.
Chapter 4
Fact 1 - Web search tools consists of four broad categories of sites that can be used individually or in combination to accomplish a Web search strategy. The four broad categories of sites that include Web search tools are search engines, directories, metasearch engines, and Web resources such as Web bibliographies.
Fact 2 - I learned that a metasearch engine searches the database's of multiple search engines for a possible match or hit in response to a user query. This Web search tool prevents a user from searching multiple search engines separately when a query can go unmatched from numerous databases.
Fact 3 - I learned that some search engines provide a clustering feature that serves as a filtering effect to group the hits in to categories. This feature is helpful because a query can have multiple definitions and the categories provide a way to narrow down a search from thousands or millions.
