How Does Ping Work?
Ping sends an Internet Control Message Protocol (ICMP) Echo Request to a network interface and then waits for a response. When the ping command is executed, a ping signal is delivered to the provided address. When the target host receives the echo request, it answers with an echo reply packet. This method has two distinct purposes: calculating round-trip time (RTT) or latency and ensuring that the target host is available. RTT is a measure of the time it takes to receive a response. Measured in milliseconds (ms), the process begins when a browser submits a request to a server and concludes when the server responds. RTT is an important performance figure for online applications.
What is Ping?
A ping is a basic Internet command that allows a user to test and verify whether a given destination IP address exists and can accept requests in computer network administration. Ping is also used for diagnosis to confirm that the computer the user tries to reach is operational. Ping can be used with any operating system (OS) that supports networking, including the majority of embedded network administration software.
