In practical usage, the terms "latency" and "ping" are often used interchangeably, but they are not the same. Latency refers to the time delay between a data packet being sent and the response being received, and it is typically measured in milliseconds (ms). This delay can be caused by various factors, including the distance between the sender and receiver, the number of network devices the data must pass through, and the connection speed between those devices. On the other hand, Ping is a specific network tool used to measure latency by sending a small data packet from one device to another and measuring the time it takes for the response to be received. The ping command is available on most computer operating systems and is often used to diagnose network connectivity issues. While ping can be used to measure latency, it is one way to do so. Other methods, such as online speed test websites or network monitoring software, can also measure latency.
