Final answer:
The topology using twisted-pair cables with modular plugs is the Star Topology. It connects all devices to a central hub using copper conduction wires that are shielded by insulators.
Step-by-step explanation:
The topology that uses twisted-pair cables with modular plugs to connect computers and other networking devices is known as c. Star Topology. In a star topology, each device is connected to a central hub or switch using twisted-pair cables, which often use modular RJ-45 plugs. Copper is a common conductor used in these cables because of its ability to easily allow electrons to move through it. The cables are typically shielded with rubber or plastic to act as insulators, preventing the electric charge from escaping.
