What is Ping, and how to use it

Ping is a function designed to check whether the local communication exists, and whether the remote site you are trying to reach is active and accessible.

When the computer receives a ping command, it sends several small "information packets" (in ICMP) to the computer that has been defined as the destination,
along with a request to return these packages. When they return, the computer knows how long it took to change the packages. Usually it is a time of about 30 milliseconds, if there is no load on the communication line.

How to use Ping?

Open a Dos window by Start > Start and press the command cmd or command (depends on your operating system).
In the window, type the command Ping Along with the IP address or the name of the computer to which you want to check communication.

For example, the command Ping walla.co.il will check communication with the Walla server.

At this stage the computer will send 4 "packets" and measure the time until they return.
At the end of the process, the average time of communication with the destination will also be displayed.

If there is no communication with the destination, or if several "packages" have not returned -
The message will appear Request Timeout - and it is recommended to check if there is a communication problem, and what the source is.
