Data flow refers to the movement of information or data from one point to another within a system or between systems. It involves the transfer of data through various processes, such as input, storage, processing, and output, in a structured and organized manner. This flow of data can be visualized as a series of interconnected pathways, where data is constantly being collected, analyzed, and distributed. Data flow is crucial in the functioning of modern technology, as it allows for the efficient and effective exchange of information, enabling businesses and individuals to make informed decisions and take action.
