A client is fetching a base HTML file with k referenced objects (k > 0) from an Internet server. Let the RTT be r. Assume that the transmission/reception time for each file and referenced objects, if any, is d. Further, the only transmission/reception bottleneck in the network is the access link through which the client is connected to the Internet. In terms of r, k, and d, compute the following delay for the following scenarios:

(a) Non-persistent HTTP with parallel TCP connections (there is no limit on the number of parallel connections). (b) Non-persistent HTTP with no parallel TCP connections.
