Answer 1

Pinging is to send a data to a port and to reveive a reply back, so as to confirm the availability of the computer.

Answer 2

In terms of ping time in a game, this referrers to the time it takes to send data to the server and back. The lower the ping time, the better your connection.
In terms of a network utility,
ping is a network utility for testing if a network host is available.
Thats the text book definition.
Not all hosts are pingable, as some sites are configured not to respond to ICMP traffic due to security concerns.
(microsoft.com is a good example)

Answer 3

Verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. The receipt of corresponding Echo Reply messages are displayed, along with round-trip times. Ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution. You can use the command like this.

Ping 127.0.0.1 (to ping your own computer)
Ping x.x.x.x (just type the IP of a computer for “x” values to ping them)

Answer 4

Ping is the duration it takes for a reply from one computer to another. Basically it measures the speed of the connection.
