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). It is physically limited by the speed of light or, practically, how fast signals can travel in wires or in the open air. As such, even low latencies of less than 50 milliseconds can add up to considerable delays.
