What is Ping or Pinging?

Ping is a computer command that you can use to check if there a connection (reachability) between two devices.

The name comes from active marine sonar terminology that sends a pulse of sound and listens for the echo to detect objects under water.

When you “ping” a device you are asking your PC to send data (know as packets) to another device to check if there is connectivity between the two. The ping command will tell you if the destination device is reachable.

When you “ping” a device you ping it’s IP address, hostname or website address. Every device that is connected to  your home Broadband  (e.g PC, laptop, smart phone, etc) or a computer network will have a unique IP address.

The IP address is automatically assigned by DHCP (stands for Dynamic Host Configuration Protocol) which is a service usually running on your broadband router and assigns IP address to all devices that join your network from a predefined list of IP addresses (know as a range).
