The browser caches the results of these lookups, but they can be slow. This typically happens once per server and takes up valuable time — especially if the server is very distant from the browser and network latency is high. 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).
