-Latency is how long something takes to happen, so obviously the shorter this is the better . The Low Latency patches ([IIRC]) go through the kernel and find a lot of the times where the kernel is busy doing something for a long time and let other processes run. This is important so that sound doesn't skip
+Latency is the delay between an event and the reaction to it . It is usually desirable for latency to be low, though low latency usually comes at the cost of throughput, which is the rate at which events can be reacted to
  
-In networking, ping(8) is often the utility used to check latency . You often hear gamers talking about "ping times" and wanting them to be very low, or more importantly for them not to change (which is called [Jitter ]) 
+In networking, latency is usually expressed in terms of "ping time", measured using the ping(8) utility. Consistent and low latency is important for network games and voice chat (see [VoIP ]) applications.

+The Low Latency patches for the [Linux] [Kernel] reduce the duration of many uninterruptible sequences, so other processes can run, preventing f.ex sound from skipping.
