Final answer:
The question discusses home network arrangements, specifically the star topology where devices connect to a central hub or router, made popular by widespread WiFi technology. Before cable, networks had to rely on broadcast towers, but cable programming's direct transmission to company hubs has changed how networks deliver content.
Step-by-step explanation:
The student's question concerns home networks and their configuration, known as the star topology. In this setup, multiple devices are connected to a central device, commonly referred to as a hub or router. This network arrangement is quite ubiquitous in modern homes due to the widespread adoption of wireless WiFi technology enabled by devices like cell phones and laptops. WiFi utilizes microwaves in the 2.4 GHz to 5.0 GHz range to wirelessly connect devices to the internet through these hubs or routers, which are also connected to the broader internet through cable or fiber optic lines.
Before cable, networks would rely on a series of local affiliates and transmission towers to broadcast their signal, which posed geographical limitations. However, with the advent of cable programming, networks are able to transmit directly to local cable company hubs, essentially bypassing the need for broadcast towers. This evolution has facilitated a shift in the way networks operate and offer content to viewers.
