Final answer:
Cables connect to each other or to a central hub through coaxial cables with conductors that are used to transmit signals effectively. These cables are connected to devices through plugs and jacks, ensuring efficient electricity or signal transfer.
Step-by-step explanation:
When discussing how cables physically connect with each other or to a central point like a switch or hub, one is typically referring to cable networking infrastructure. In a typical network setup, cable stations transmit programming to a local cable company hub, which then distributes the content to consumers. This involves the use of coaxial cables, which consist of two concentric conductors separated by insulation, ensuring that the electrons move freely without the electric charge escaping outward due to the insulating sheath.
Devices like computers may connect to the network through a computer jack, where a plug attaches to a port, allowing electrical signals to travel between devices. This is how, for instance, a power adapter delivers electricity from a wall socket to a laptop computer. Similarly, when one flips on a light switch, the electricity travels through wires to reach the light, demonstrating the fast transmission of electrical signals through the conductors within cables.
