This is a very interesting analogy! You’ve done a great job of comparing the functionality of TCP/IP to echolocation. It is a very helpful way to understand how information is exchanged within a network. However, I do think that it’s important to remember that TCP/IP is a more complex protocol than simply sending out a signal and waiting for a response. For example, TCP/IP uses a variety of mechanisms to ensure that data is delivered reliably and securely, even if the network is congested or unreliable. But, it is still a helpful way to visualize the process of how information flows within a network.
