Johnny is a web application designer who is currently debating whether to use persistent or non-persistent HTTP requests for his application. Assuming a web page requires the transfer of 8 objects from the server to the client, please assist Johnny in making this decision by computing how long it would take to receive 8 objects at the client when Johnny is: A. Using persistent HTTP requests B. Using non-persistent HTTP requests Please assume the following: . The transfer of an object from the server to the client including the TCP Acknowledgement (ACK) by the client to the server takes 0.01 seconds. · The TCP handshake process takes 0.02 seconds. • The TCP teardown process takes negligible time and may be ignored.
