Forks are actually the changings that are made in a blockchain's protocols in order to improve the functioning of the Blockchain or improve the features of the chain like security, scalability, transaction speed and many more. These forks could be hard or soft forks depending on the extent if the agreement between the developers and the nodes of the blockchain.

Hard forks are usually know as the the kinds of forks that emerge from a dispute between the blockchain network's creators and stakeholders.

Yes brother, you are very right here. Hard Forks are happened due to the disagreement between the developers or the nodes of a chain on the proposal for making changes in the protocols. Hard Forks leads to the separation of two discrete blockchains that work separately from each other.
