Spoke is a term that refers to a rod or bar that connects the center of a wheel to its outer edge, providing structural support and stability. Spokes are commonly found in bicycles, cars, and various types of machinery, helping to distribute weight and maintain the wheel's shape during movement. In a broader context, "spoke" can also refer to a part of a communication network, where it connects a central hub to various endpoints. This concept is often used in discussions about technology and data transfer, illustrating how information flows from a central source to multiple users or devices.
