Limiting the visibility of information in a program primarily serves to ensure that components only access the data they absolutely need. This principle is often referred to as encapsulation in software design, where the internal workings and data of a component are hidden from other components. By restricting access to only the necessary information, it minimizes the risk of unintended interference and promotes a clear interface. This design approach aids in maintaining integrity and security, as it prevents components from erroneously or maliciously modifying data they do not own.

Additionally, this practice supports greater modularity, making it easier to understand and maintain each component individually. When components interact with well-defined interfaces rather than accessing shared data freely, it reduces dependencies between them, leading to a more robust and flexible software architecture. Overall, this principle enhances reliability by enforcing data integrity and creating a more predictable environment for software behavior.
