high latency means you have a good connection, low latency means you have a baad connection

Many systems are dominated by throughput limitations or by latency limitations. For example, in online gaming, latency issues are a constant problem.

If you shopped for RAM put into your computer to make sure your gaming is the fastest it can be, then the lower the latency the faster the RAM. Latency is the time when the memory controller starts to grab a line of code, there is a delay and when RAM sends out the line of code there is another delay. The time is takes RAM to find and send code is called latency. So when shopping find RAM with the lowest latency.

A transcontinental fiber link might have many gigabits/sec of bandwidth , but the latency will also be high due to the speed of light propagation over thousands of KM.

In constract a 56 kbps modem calling a computer in the same building has low bandwidth and low latency

Latency is defined as the network speed in which the information being broadcast from the original server reaches the individual's device by measurement of milliseconds. This means that a lower latency will allow more information to be sent or received and thus, creating a better experience. Improving low network latency can be accomplished by establishing more latency-sensitive software so that multiple tasks and improved performance can occur.
