What does network latency affect in computing?

Network latency significantly impacts the speed of data transmission because it represents the time it takes for data to travel from the source to the destination. When latency is high, there are delays in the transmission of data packets, which can slow down communication between devices. This is particularly relevant in applications that require real-time interactions, such as video conferencing, online gaming, and live streaming.

In a network, lower latency leads to quicker responses and a more seamless experience for users. For instance, in scenarios where large amounts of data or multiple requests are being sent back and forth, even a slight increase in latency can result in noticeable delays, affecting the overall performance. Hence, understanding network latency is crucial for optimizing data transmission speeds and enhancing user experience in computing environments.
