Description: Inherent latency refers to the natural delay in data transmission due to the physical properties of the network. This phenomenon is an intrinsic characteristic of any communication system, as data must travel through various media, such as fiber optic cables, wireless networks, or even air. Latency can be influenced by several factors, including the distance between the sender and receiver, the speed of light in the transmission medium, and the processing that data must undergo in intermediate devices, such as routers and switches. In terms of quality of service (QoS), inherent latency is a critical aspect, as it can affect user experience in time-sensitive applications, such as video conferencing, online gaming, and real-time video streaming. Latency measurement is commonly performed in milliseconds (ms), and low latency is desirable to ensure smooth and efficient communication. Therefore, understanding and managing inherent latency is essential for designing networks that provide a high level of quality of service and meet user expectations in an increasingly demanding digital environment.
