Detailed explanation-1: -Multiple objects can be sent over a TCP connection between client and server in a persistent HTTP connection. Explanation: Persistent connections are kept active after completing transaction so that multiple objects can be sent over the same TCP connection.

Detailed explanation-2: -In non-persistent HTTP, the client opens a TCP connection to the server, sends at most one object over the connection using the request/response, and then closes the connection. Thereby, downloading multiple objects requires multiple connections. In persistent HTTP, the client opens a TCP connection to the server.

Detailed explanation-3: -Pipelining allows a client to make multiple requests without waiting for each response, allowing a single TCP connection to be used much more efficiently, with much lower elapsed time.
