How to use PING command ?

ping command tells you if the connection between your computer and a particular domain is working correctly.

Type at command prompt :  

ping  -t  192.168.0.1

If the results show a series of replies, the connection is working. The time shows you how fast the connection is.

If you see a "timed out" error instead of a reply, there is a breakdown somewhere between your computer and the domain.
