Which of the following systems is primarily focused on data flow?

The focus on data flow is most prominently associated with IT Systems. These systems are designed to manage, process, and transmit data efficiently across various applications and networks. IT Systems facilitate the handling of information and ensure that data can flow seamlessly between users, databases, and applications. The design and architecture of IT systems prioritize data integrity, availability, and consistency, which are essential for effective decision-making and operations within an organization.

In contrast, while other systems like OT Systems and Manufacturing Systems may involve data, their primary functions are centered around operational technologies and production processes rather than solely focusing on the flow of data. Networking Systems, though vital for data transmission, serve as the medium for data exchange but do not encapsulate the comprehensive management and processing characteristics of IT Systems. Thus, the emphasis on the flow of data makes IT Systems the correct answer in this context.
