Is USDC a dollar?

Excuse me, but could you clarify something for me? The term "USDC" has been mentioned, and I'm wondering if it's essentially a digital representation of the United States dollar. Is USDC essentially a dollar, but in a digital form, or is there more to it than that? I'm interested in understanding the intricacies of this cryptocurrency and how it relates to traditional currencies like the USD. Could you elaborate on the similarities and differences between USDC and the US dollar?
