• Federated Learning (FL) is the new efflorescing technology of Artificial Intelligence (AI) that deals with privacy-preserving aspects in distributed scenery-based applications. Federated learning mainly focuses on collaborative decentralized and distributed learning frameworks. Federated learning utilizes machine learning and deep learning models that train cooperatively with heterogeneous devices having different constraints. The impressive significance of the federated learning concept is privacy and security concerns, real-time predictions, infrastructure efficiency, and data diversification. The core classification of federated learning is Horizontal Federated Learning (HFL), Vertical Federated Learning (VFL), Federated Transfer Learning (FTL), cross-silo federated learning, and cross-device federated learning.The applicability of federated learning is explored in different domains such as
