Latency is the time it takes for a signal to travel from one point to another. It is an important factor in many applications, including gaming, video conferencing, and web browsing. High latency can cause delays and interruptions, while low latency can provide a more seamless experience.
There are a number of ways to check latency. One common method is to use the ping command. The ping command sends a series of packets to a specified destination and measures the time it takes for each packet to return. The average time it takes for the packets to return is the latency.
