How does latency affect communication?

Latency refers to the time it takes for data to travel from the source to the destination in a communication network. When latency is present, it introduces a delay in the transmission of information. This delay can manifest as a pause or lag in communication, especially noticeable during real-time interactions such as voice calls, video conferencing, or online gaming. High latency can lead to disruptions in the flow of conversation, delayed responses, and an overall degraded experience for users.

Understanding the impact of latency is crucial in optimizing network performance and ensuring efficient communication, as it directly affects the user's ability to interact in a timely manner. For instance, in scenarios where immediate feedback is necessary, such as during operational planning in the military, even a small amount of latency can significantly impact decision-making processes. Thus, addressing latency is vital for maintaining effective communication channels.
