Q5. Imagine you are using a mobile application that needs to fetch data from a specific webserver. Assume the mobile application knows the IP address of the web server. The app requests a data payload from the URL, which consists solely of a small HTML file. With RTT0 representing the RTT between your device and the web server, and considering negligible transmission time for the HTML file, calculate the total time elapsed from when the request is made by the app to when the data is received? Q6. Consider Q5, now assume the HTML file includes references to six additional small images hosted on the same server. Ignoring the actual data transmission times and assuming that there is a direct link between your mobile and the webserver, estimate the total time needed to download the full webpage when using: Non-persistent HTTP Persistent HTTP without using pipelining Persistent HTTP with pipelining Non-persistent HTTP configured to allow three parallel TCP connections. Note that for N parallel connections each get 1/N of the link bandwidth.
