. Please read Chapter-6, Section 6.7 Retrospective: A Day in the Life of a Web Page Request. Submit a brief summary of the 4 subsections (6.7.1-4). After reading this, you can understand what are the processes that happen after joining a network through the web page request. I have covered almost all the topics related to those operations (if you find something not covered, those you can understand after reading those sections).
