Explain the concept of network latency.

Network latency refers to the delay or lag in the transmission of data packets over a network. It is the time taken for a data packet to travel from the source to the destination. Latency can be caused by various factors such as the distance between the source and destination, the number of network devices the data packet has to pass through, and the congestion or traffic on the network. High latency can result in slower response times, delays in data transmission, and can negatively impact real-time applications such as video streaming or online gaming.
