Gate2020 cs Q18

18Assume that you have made a request for a web page through your web browser to a web server. Initially the browser cache is empty. Further, the browser is configured to send HTTP requests in non-persistent mode. The web page contains text and five very small images. The minimum number of TCP connections required to display the web page completely in your browser is ______.

Note – Numerical Type question

Option : B
Explanation :
In non-persistent HTTP, each packet takes 2 RTT (Round trip Time): one for TCP connection, one or HTTP Text (Image file As, it is given text and 5 images that totals 6 objects.)
So, it takes 12 RTT in total. But,
12 RTT includes 6 HTTP connections + 6TCP connections.
So, the minimum number of TCP connections required is 6.
