1. The nearest Google server from UNT DP is in Lewisville, TX. The copper cable connection between UNT DP and the Google server is 25 km long and the propagation speed through the copper cable is 2.5 x 10⁸ m/s. The transmit rate and receive rate is 2,000 Mbps. Now consider the HTTP protocol and suppose that initial downloaded page from Google server is 10,000 bits in size, and that the initial downloaded page contains 4 referenced objects from the Google server. Each referenced object is 50,000 bits long. Assume packets containing only control signals (ACK or handshaking) are 200 bits long. Answer the below questions. Assume that N parallel connections each get 1/N of the link bandwidth.
   1. What would be the total time required to download the complete page using non-persistent HTTP? (7 Points)
   2. What would be the total time required to download the complete page using 2 parallel instances of non-persistent HTTP? (7 Points)
   3. What would be the total time required to download the complete page using persistent HTTP? (7 Points)
   4. Which is better non-persistent HTTP, parallel instances of non-persistent HTTP, or persistent HTTP? (1 Points)
