Final answer:
HFC stands for Hybrid Fiber-Coaxial, a telecommunications technology that combines optical fiber and coaxial cable to provide various services like broadband internet and television.
Step-by-step explanation:
In the context of a neighborhood junction, HFC stands for Hybrid Fiber-Coaxial. This is the technology often used in telecommunications to deliver a wide range of services, such as broadband internet, television, and voice services, over the same infrastructure. HFC networks combine optical fiber and coaxial cable; the fiber extends from the cable operators' facilities to a point near the user, while coaxial cable provides the connection between the user and the fiber node.
