What performs the instructions by directly interacting with business applications in RPA?

RPA Bots are specifically designed to execute predefined tasks by interacting directly with various business applications. These bots simulate human actions to perform repetitive tasks such as data entry, information retrieval, and processing transactions. They operate on the user interface of applications, making them capable of managing tasks across different software tools without requiring any changes to the underlying systems.

In the context of RPA, the primary focus is on automation through these bots rather than other components like automation scripts, user interfaces, or service agents. Automation scripts may be used to define the sequence of tasks but do not interact with the applications themselves. User interfaces represent the visual elements of applications but do not perform tasks. Service agents typically refer to support roles or systems that assist in managing services rather than executing RPA tasks.

Thus, RPA Bots are the core operational entities that execute the processes by mimicking user interactions, making them the correct choice for the question posed.
