Applied Mock Test

Question

How Long it will take if a person clicks on a link to retrieve the HTML file referring to 12 objects. We are using the Non-persistent HTTP connection with 6 parallel TCP connections. Assume the transmission time for any file is 0 ms. The round trip time between the person and the sever is RTT ms.?

 

Answer 1

Initial 2 RTTs are required for TCP connection and others for the HTML page.

If we have to send 12 objects for without parallel connection = 24 RTTs required  [ one for TCP and or for object]

But we have 6 parallel connection = 1 TCP + 6 objects in 6 parallel connection at a single time + 1 TCP + 6 parallel connections objects = 4  RTTs

A total of 6RTT will be required.
