These two words are very common in work time. In work you need other’s trust and they must have confidence to you, so that you can do your work effictively. But they are not just unified meaning, since they are relative either in most time.
You show the confidence to others and people do trust in you. This is very reasonable. You will get it when you show something. But once you do something evil, people will not keep the confidence to you.
It’s also exist in computer and networks. You trust in all your devices and you have confidence to them, so you can write any security information or upload any files on them. Once you doesn’t trust the device, maybe because some one installed a Key logger in your pc, then you must not to do some security work unless you resolve this super-spy in your computer. This theory is also useful for our home security. The most difference is that you can have a hidden spy camera in your home :-).
