What does it mean when two systems are interfaced?

When two systems are interfaced, it refers to the ability of those systems to share data and information seamlessly. This means that they can communicate with each other effectively, allowing them to access and utilize the same data resources. Interfacing is crucial for integration purposes, as it enables different software applications or hardware devices to work together, improving efficiency and reducing the chances for errors that can occur when data needs to be manually transferred or entered.

In a payroll context, for instance, interfacing may involve linking a timekeeping system with payroll software, enabling the payroll system to automatically receive employee hours worked. This direct communication saves time and minimizes the risk of discrepancies in data entry. Therefore, sharing data needed by both systems is a core component of what it means to have them interfaced.
