How Tezos works?

Could you please explain to me in simple terms how Tezos operates? I'm interested in understanding its underlying technology and the way it differs from other cryptocurrencies. Could you also elaborate on its self-amending capabilities and how they contribute to its uniqueness? Additionally, I'm curious about its governance model and how it affects the decision-making process within the Tezos community. Could you provide some insights into that as well? Thank you for your time and assistance.
