Which term describes a connection point for external devices that allows for data transfer?

The term that describes a connection point for external devices that allows for data transfer is a port. In the context of computer hardware, a port serves as an interface between the computer and external devices, such as printers, keyboards, mice, and storage devices. Ports facilitate the transfer of data by providing the necessary physical and logical connections needed for communication. For instance, USB ports are widely used for connecting various peripherals, allowing them to communicate with the computer effectively.

Other terms like "node," "switch," and "hub" refer to different concepts within networking and computing. A node typically refers to any active electronic device on a network that can send or receive data, while a switch is a device that connects multiple devices on a network, forwarding data between them based on MAC addresses. A hub, on the other hand, is a basic device used to connect multiple Ethernet devices, making them act as a single network segment, but it operates without the intelligent data forwarding found in switches. Therefore, port is the specific term that accurately describes a connection point for data transfer among external devices.
