Definition: The term "subexternally" is a technical term in computer science and networking, referring to the process of communicating with another system or device through a single point of entry. This involves using multiple interfaces or ports to connect one system to another, rather than having separate devices that communicate directly with each other. In terms of programming languages, subexternally refers to the practice of writing code in a way that allows for communication between different parts of an application or system, without the need for direct interaction
