HTML Processing Once a web page’s HTML file has been downloaded, the browser begins to process the contents line by line, translating code into the visual website that users interact with. It also opens up the possibility for more effective use of caching strategies, potentially enhancing load times further.

All these resource hints use the rel attribute of the <link> element that you’ll be familiar with finding in the <head> of your HTML documents. The browser caches the results of these lookups, but they can be slow. You might think of a prefetch as being a bit like adding a file to the browser’s cache.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).
