Can it be used to check Ip connectivity to the internet? What is a loopback test of the computer.
Simply, you are using this tool to check is some other doamain or computer available online. Imagne that you are calling somebody, when he anwers to you that is the resoult of PING...
ping is a command that sends an ICMP echo packet to an IP address.
it is named after the action of sending a short SONAR burst to look for submarines. this is called a ping.
an ICMP echo packet is returned by the destination address if and when it is received.
because a) ICMP is an unreliable protocol (no error correction) and b) because some people disable it (in the name of security) - there is no guarantee that NOT receiving a response means that the far end is down. but if it is received it means that the far is is reachable and is at least running an IP stack.
IT came from the sport game "PING PONG" which means you ping if the ball cames back this means there is some on the other side answering your request.
Ping : is test of connectivty
this mean when you ping to ip , you insure if the ip youn ping to it in sam network and work or no
