What do you call the hardware and software that manages data transfer among various devices?

The term that accurately describes the hardware and software responsible for managing data transfer among various devices is network infrastructure. This includes the physical components, such as routers, switches, and cables, as well as the configurations and protocols that facilitate communication between devices within a network. Network infrastructure ensures that data can move efficiently and securely between different endpoints, enabling seamless connectivity and access to resources.

While communication framework might sound relevant, it generally refers to the methodologies and standards for communication rather than the physical and software components that make data transfer possible. Information routing focuses on directing packets of data through the network but does not encompass the entire scope of hardware and software involved in managing data transfer. System architecture, on the other hand, pertains to the overall structure and organization of a system, which includes software design but does not specifically address the hardware and mechanisms used for data transmission.
