Turns out, I'm totally wrong. According to TechRepublic, there's a big difference betweeen the CIO and the CTO, and it has to do with who you serve. The CIO serves an organization's internal audience, or its staff. The CTO focuses on an organization's external audience, or clients, stakeholders, donors, etc. Check out the full breakdown.

So, what happens if you're the only techie at your organization? Are you the CT&IO?
