Latency on the Internet refers to the delay that occurs between a user sending a data request and receiving the requested data, i.e., the time it takes for a data packet to travel from source to destination on a network. This delay is measured in milliseconds and is influenced by various factors, such as the physical distance between the sender and receiver, the number of network devices through which the packet passes, the processing time of the devices, and the quality and capacity of the network connection.
A slow Internet connection and many people trying to connect at the same time can affect the speed of data transfer. Slow response times, which can occur when streaming video, playing online games or surfing the Internet, are the result of high latency.
Network administrators can reduce latency by optimizing network paths, increasing network capacity, or prioritizing network traffic.
