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?

Even when the head is held upright, its center of gravity is not directly over its major point of support, the atlanto-occipital joint. The splenius muscles in the back of the neck must therefore exert a force to keep the head up. Use the information in the figure below. The mass of the head is 5.0 kg. The weight of the head is located 0.025 m from the joint, and the splenius muscles are located 0.05 m from the joint. DF 3.3.png
