A computer command used to diagnose network problems also lets you see how data hops across the internet.
There is a simple way to see traffic jump from one computer to another on the internet: traceroute. It’s a command you type into a command line interface (CLI) software tool to see how your data travels from your computer to a locations you define.
For example, you can see how data travels from your computer to yahoo.com, nytimes.com, bbc.co.uk, or any computer connected to the internet.
Data sent is a packet, a small message that requests information from other computers. Based on responses, your data navigates its way from your computer to your destination. Kind of like climbing up a rock wall one handhold at a time.
