Question
Consider an HTTP server and client as shown in the figure below. Suppose that the RTT delay between the client and server is 13 msecs; the time a server needs to transmit an object into its outgoing link is 1 msecs. Any other HTTP message not containing an
object has a negligible (zero) transmission time. Suppose the client again makes 106 requests, one after the other, waiting for a reply to a request before sending the next request. Assume the client is using HTTP 1.1 and the IF-MODIFIED-SINCE header line.
Assume 47% of the objects requested have NOT changed since the client downloaded them (before these 106 downloads are performed).

Computer Networks:

Computer Networks deals with the communication and sharing of information between different computer systems. Computer networks are essential for the operation of the internet, as well as for communication within organizations and businesses. They enable the sharing of resources such as printers and servers and facilitate the transfer of data and files between connected devices.

A client is a device or program that requests information or resources from another device or program on the network. Examples of clients include web browsers, email clients, and file transfer programs. Clients typically initiate the communication and send requests to servers, which respond with the requested information or resources.

A server is a device or program that provides information or resources to clients on the network. Examples of servers include web servers, file servers, and email servers. Servers are designed to be available and respond to requests from clients, typically waiting for incoming requests and responding to them as quickly as possible.
