What is Network Latency?
Network latency is simply defined as the time delay observed as data transmits from one point to another. Usually, to determine network latency, the origin and destination points are used. In some cases, network latency may be defined by the time it takes some form of data to make a full circuit back to the originating point. While it may seem counterproductive to use the round-trip time, it actually can be a much better measure of overall network performance. This is because computers in the process of sending and receiving bytes are in constant communication with each other. Even the one receiving will send information back to the sending machine. Therefore, network latency can easily be determined by the round trip time. The main assumption in network latency is that the time of transmission between the origin and destination should be instantaneous. Of course, there will always be some delay. Even transmission at the speed of light is not instantaneous and can be measured with very
