What is Ping, Example, How it works ?
When a host (often a computer or server) is connected to an Internet Protocol (IP) network, the “Ping” utility tool is used to determine whether or not the host can be reached. Sending Internet Control Message Protocol (ICMP) Echo Request messages to the host that is the target of the operation and then waiting for an Echo Reply gives it the ability to function. The term “ping” originates from sonar technology, where it refers to the pulse of sound that is sent out via the system in order to identify things.
