  1. 1. How Internet Search Engines Work Internet Search Engine Database Link Keywords Reference
  2. 2. Internet search engine An Internet search engine is a tool designed to search for information on the World Wide Web. The search results are usually presented in a list and are commonly called hits. The information may consist of web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories. Unlike Web directories, which are maintained by human editors, search engines operate algorithmically or are a mixture of algorithmic and human input.
  3. 3. Database A database is a structured collection of records or data that is stored in a computer system. The structure is achieved by organizing the data according to a database model. The model that is most commonly used today is the relational model. Other models such as the hierarchical model and the network model use a more explicit representation of relationships.
  4. 4. Link Link is an open source text and graphic web browser with a pull-down menu system. It renders complex pages, has partial HTML 4.0 support , supports color and monochrome terminals and allows horizontal scrolling. It is oriented toward visual users who want to retain many typical elements of graphical user interfaces in a text-only environment. The focus on intuitive usability makes it suitable as a web browser for low-end terminals in libraries.
  5. 5. Keywords In computer programming, a keyword is a word or identifier that has a particular meaning to the programming language. The meaning of keywords — and, indeed, the meaning of the notion of keyword — differs widely from language to language. In many languages, such as C and similar environments like C++, a keyword is a reserved word which identifies a syntactic form. Words used in control flow constructs, such as if, then, and else are keywords. In these languages, keywords cannot also be used as the names of variables or functions. Some languages, such as PostScript, are extremely liberal in this approach, allowing core keywords to be redefined for specific purposes.
