What is the time called that it takes for a packet to move through a network?

The time it takes for a packet to move through a network is called "latency." It is typically measured in milliseconds and reflects the delay from the moment a packet is sent until it reaches its destination. Latency can be affected by various factors, including network congestion, routing paths, and the physical distance between devices. Lower latency is generally preferred for applications requiring real-time communication, such as video conferencing or online gaming.
