Web Science/Part2: Emerging Web Properties/Modeling the Web as a graph/Topology of the web graph/quiz

{What is true about the largest strongly connected component of the World Wide Web} - It consists only of the Web pages of the Wide Web Consortium and CERN. + the diameter will be surprisingly small (presumably less than 100) + there is at least one path of links from one url to any other url in the strongly connected component - every node inside the strongly connected component has at least 3 incoming edges - every node inside the strongly connected component has at least 3 common nodes with any other node

{Which of the following statements about the bow tie structure of the web are true?} - the incomponent of the bow tie model can easily be crawled. - the out component cannot be crawled since search engines cannot find it. + two random nodes from the in component can have a path between them + two random nodes of the out component can have a path between them + if a new link from a node of the out component is created to a node of the in component both nodes will then be part of the strongly connected component + the strongly connected component is the intersection of the in component with the out component - the strongly connected component is the union of the in component with the out component
 * actually search engines have a hard time to know where to find pages that have no incoming links from the strongly connected components
 * the out component can be found easily
