Is Tao Te Ching the same as Taoism?

Excuse me, could you clarify the distinction between the Tao Te Ching and Taoism? Are they one and the same, or are they two separate entities with distinct meanings and applications? If they are different, how do they relate to each other, and what are the key differences that set them apart? I'm interested in understanding the nuances and connections between these two concepts, and how they are perceived and understood within the realm of spirituality and philosophy.
