What is the significance of the infinity value in the Dijkstra Algorithm?

The infinity value in the Dijkstra Algorithm is used to represent an initial distance value for all nodes except the source node. It signifies that the distance to reach those nodes from the source node is currently unknown or unreachable. As the algorithm progresses, the infinity value is updated with the actual shortest distance found so far.
