PING

PING is one of the most networking utilities that is used for network troubleshooting. It is a computer network administration network diagnostics utility used to test the reach ability of a host on an Internet Protocol (IP) network. In the same time it measure the round trip time for messages sent from the originating host to a destination computer.

PING operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an Internet Control Message Protocol (ICMP) response. In the process it measures the time from transmission to reception (round trip time) and records any packet loss.

Here the results of the test are printed in form of a statistical summary of the response packets received, including the minimum, maximum, and the mean round-trip times, and sometimes the standard deviation of the mean.

How to use
PING:

Here we can identify the usage of PING command for identifying different types of network diagnostic tests as follows,

1. Can be use to determine whether a destination can be reach and to determine how long it takes to bounce a packet off of another site
   
2. Can use to probe either a domain name or an IP address. If ping a domain name, it helpfully displays the corresponding IP address in the response.
   
3. Can get to know that when
   ping a device PING rest will be send and it send sends back the echo. If receive a reply the device is working fine and the connection is fine
