Make the following assumptions: (i) client and server are connected by a direct link, whose transmission rate is R, (ii) round-trip time (RTT) between client and server is denoted by T. (iii) the base HTML page is of size F, and the size of each of its referenced objects is O (iv) there are N referenced objects in the base HTML page, where N is at least 1. a) Write down a formula for the total delay to download the HTML page and its referenced objects assuming non-persistent single connections. b) Same as question 1 except assuming non-persistent N parallel connections. With parallel connections, the client can request all the Nm referenced objects by opening N simultaneous connections. c) Same as question 1 except assuming a persistent connection with pipelining.
