Yes, a private cloud means a corporate network - but the infrastructure is of the same kind as a public cloud - abstracting the service from the underlying hardware to make it more available/robust and cheaper to operate.
A public cloud, as I've seen the term widely used, seems to mean more than simply "online". It means shared infrastructure, as in Amazon's S3 or other environments where you're sharing networking and compute resources with other entities in a hosted environment. In this kind of case, your service is running in the same hardware environment as other orgs - same network, same set of physical hosts, etc. I'm not yet convinced that such an environment *can* be secured to any reasonable degree. Thus, the fact that my bank is putting their infrastructure in a private cloud doesn't bother me - but if they're putting it in a public environment, where they've given up control over who else runs in that environment and the conditions under which it's maintained, then I'm withdrawing my money and closing my account as soon as I find that out. If I have to, I'll go to cash - it's about trust, and I don't trust giving us control over my money to some marketing hype.
