Non-persistent connections require a separate connection to be created for every object that is transferred. For a webpage, this would mean a separate connection for every image on the page.

However, non-persistent connections can also simplify things by reducing connection overhead; limiting sender and receiver-side variables, buffers, and reducing overall RTT. Persistent connections, such as those offered by TCP, provide a number of advantages for modern web applications such as websites where many different objects are transferred.

Imagine, browsing Pinterest, and having to negotiate a separate connection for every image loaded onto the screen! Persistent HTTP connections require a bit more overhead to setup.

How does a client request a non persistent connection? A nonpersistent connection is the one that is closed after the server sends the requested object to the client. With persistent connections, the server leaves the TCP connection open after sending responses and hence the subsequent requests and responses between the same client and server can be sent. What is meant by persistent data? Persistence is "the continuance of an effect after its cause is removed".

In the context of storing data in a computer system, this means that the data survives after the process with which it was created has ended.
