How much information is being sent per how ever many ms (milliseconds) or s (seconds) it takes. You can also test wether or not a server is not working properly or your wifi, or your computer for that matter as it isn't sending data fast enough so that you can get a "clear" connection.

The diagnostic tool ping can be used for many things such as to verify IP-level connectivity. When you're troubleshooting, ping is used in order to send an ICMP echo request to a target host name or IP address (ex. facebook.com or youtube.com). IT's would use ping whenever they need to verify that a host computer is able to connect to a TCP/IP network. You could also use ping to isolate network hardware problems as well as incompatible configurations.

Example of Pinging...

 

C:\>ping -n 2 01 1450 131.107.8.1
Pinging 131.107.8.1 with 1450 bytes of data:

Reply from 131.107.8.1: bytes=1450 time<10ms TTL=32
Reply from 131.107.8.1: bytes=1450 time<10ms TTL=32

Ping statistics for 131.107.8.1:
      Packets: Sent = 2, Received - 2, Lost = 0 (0% loss),
Approximate roundtrip times in milliseconds:
       Minimum = 0ms, Maximum = 10ms, Average = 2ms

When you ping, by default, the ping waits 4,000ms (or 4 seconds) for each response to be returned before displaying that the request has timed out message. You can use the -w (wait) option to specify a longer timeout. 

If you get the message saying that request has times out, it means that there was no response to the ping in the default time period (1 second). Possible errors...

  • Ping command is blocked at the corporate or personal firewall level
  • The router is down
  • Destination host is down
  • No route back to your computer
  • Latency of the response is more than one second

Pinging is a really good way of testing network connectivity and that's why IT's use it.
