4) (25 points)  Suppose you are downloading a web page consisting of a base HTML page of size B bits and 21 embedded objects, each of size E bits, using different forms of HTTP. Let RTT (in seconds) denote the round trip time between your host and the web server. Suppose that the transmission bit rate over a TCP connection is R bit/sec. a) Suppose that persistent HTTP without pipelining is used. How long does it take to download the web page? b) Suppose that persistent HTTP with pipelining is used. How long does it take todownload the web page? c) Suppose that non-persistent HTTP (without parallel connections) is used. How long does it take to download the web page? d) Suppose that non-persistent HTTP with 7 parallel connections isused.  How long does it take to download the web page?
