Is tunnel a shortcut connection in internet? I read that tunnel is like protective cover for data. How this protective cover is created. What is this protective mean? Is it like Encryption?
There are two fundamental problems with the question.
- The OP quotes from an unknown source, and we have no idea what the original writer was talking about
- The part about "How this protective cover is created" is too broad. Furthermore without some reference for the kind of tunnel the OP is talking about, the whole thing is open-season for pot-shot answers which speculate about the OP's actual intent.
Is he asking about:
- IPSec Tunnels?
- SSL VPN tunnels?
- PPTP Tunnels?
- SSH Tunnels?
- OpenVPN Tunnels?
A person might respond that it doesn't matter because you can just write a generic answer about some encrypted tunnel. However, that's beside the point; we look for:
practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
