Are jitō and daimyo the same?

Could you please clarify for me if jitō and daimyo are interchangeable terms, or do they have distinct meanings within their historical and cultural contexts? I'm particularly interested in understanding the differences, if any, in their roles, powers, and responsibilities in feudal Japan. Additionally, I'm wondering if there are any specific historical events or periods where the usage of these terms might have been more prevalent or significant. Thank you for your assistance in clarifying this matter.
