Final answer:
Repeaters and Hubs are the devices that regenerate a signal out of all connected ports without examining the packet contents. These devices act as basic signal amplifiers at the network's physical layer.
Step-by-step explanation:
The hardware devices that regenerate a signal out of all connected ports without examining the frame or packet contents are A. Repeater and B. Hub. Repeaters and hubs operate at the physical layer of the OSI model and simply regenerate the electrical signal to extend the reach of the network. They do not inspect the contents of the frames or packets they are repeating or distributing. Therefore, these devices are unable to determine the destination of that data and broadcast it to every connected port. Conversely, Bridges, Switches, and Routers operate at higher layers of the OSI model, which allow them to examine and direct data to a specific destination based on its contents, making them more intelligent network devices compared to repeaters and hubs.
