What is Ping?
Ping is a very universal command between all the operating systems. You can use it to test if you can reach your target and how much time it will take to do it. Ping sends Internet Control Message Protocol (ICMP) packets to the destination. Then it waits for the echo reply. It can show statistic for this request, errors and packet loss.
When you use this command, you will send few echo requests, usually 4. Then you will receive a result for each of them, that indicates if they were successful, how much data was received, the time it took for the response and TTL (Time to live).
