Random Forest and Decision Tree Algorithm

As Random Forest is a collection of Decision Trees following bagging concept, so when we move from one Decision Tree to the next Decision Tree then how is information learned by last Decision Tree moves forward to next ?
Because as per my understanding there is nothing like trained model which gets created for every Decision Tree and then loaded before the next Decision Tree starts learning from the misclassified error.
So how does it works ?

"the next Decision Tree starts learning from the misclassified error" just exactly described gradient boosted decision trees

Additionally, there is most definitely a difference between bagging and random forest, and it has to do with how samples and subsets are selected for inclusion in the 'stumps' or sub-trees

Trees in RF are independent, so what you assume here simply does not happen. It seems you are confusing RF with the gradient boosted trees. In any case, the question is off-topic for SO and better suited for Cross Validated.
