End-to-end connectivity

Imagine you have a toy telephone set in your hand. One handset has a speaker and the other has a microphone. You want to talk to your friend who is sitting across the room on the other side of the table.

To have a conversation with your friend, you need to make sure that the wire that goes from the speaker of your phone to the microphone of your friend's phone is not broken and there is nothing obstructing the way.

This is how end-to-end connectivity works. It refers to a connection between two devices or computers where data can flow smoothly and without interruption from one end to the other.

Just like the toy telephone example, end-to-end connectivity requires that every link in the chain of connections (such as Wi-Fi, Ethernet cables, routers, and switches) is working well and not causing any problems.



In simpler terms, end-to-end connectivity means that two devices or computers can talk to each other without any obstacles or problems along the way, so they can have a smooth conversation or communication.
