The ping is a process to check whether a remote host is available or not.
Ping does this in following way:
First it send an ICMP Echo Request packet to the host,if host send an ICMP Echo Reply packet then it means that host is alive and if it does not send an ICMP Echo Reply packet then it means host is dead.It usually used to check whether connection to other host(computer,printer,fax) is valid or not.

The ping is a utility that check connection to destination(Like other computer,fax,printer,router.etc.) is intact or not and also check how long it takes.Ping(short for Packet Internet Groper) use TCP/IP service that allow you to see whether you are reachable to another host or not.It is a fast test to check connection availability.
You can test connection with another host using his IP address

Syntax:
PING [options] destination_host

Type above command in "Run".
eg.ping 123.123.123.123

Ping is a fast process to check network availability.If you are not able to ping one web site ,but if you are able to ping other web sites then it means that your internet connection is working but that one site is may be down.If you are not able to ping any of the web site it means your internet connection may be not working.ping is based on Internet Control Message Protocol (ICMP) .When you ping any site ,you send ICMP request to that site and if that site is working or up ,that site then send you ICMP reply .If that site does not send ICMP reply ,then it means that site is down.
