Why is 32-bit better than 8-bit?

Could you elaborate on why 32-bit technology is often considered superior to 8-bit technology? I'm curious about the specific benefits it offers in terms of processing power, memory capacity, and overall performance. Is it simply because 32-bit allows for more data to be processed at once, or are there other factors at play as well? It would be great if you could provide some real-world examples to illustrate these advantages.
