Ping is a network diagnostic tool that measures the round-trip time (RTT) it takes for a packet to travel to a destination and return.

Elaboration:

• Uses ICMP (Internet Control Message Protocol) to check connectivity.
• Lower ping times (<20ms) indicate a fast and responsive network.
• High ping values (>150ms) can cause lag in gaming, VoIP, and video calls.

Example:

Using the ping command in a terminal:

ping google.com

This checks how fast your computer can communicate with Google’s servers.
