What is the primary function of a cable in networking?

The primary function of a cable in networking is to connect devices or share resources. Cables serve as the physical medium facilitating communication between networked devices, such as computers, switches, routers, and servers. When devices are connected by cables, they can effectively exchange data, access shared resources, and operate as part of an interconnected network.

While boosting network signals, encrypting communication, and amplifying data transfer speeds are important aspects of networking technologies, they aren't the fundamental roles performed by cables themselves. Cables primarily serve to create physical and logical connections, enabling data transmission between devices within a network. This foundational connectivity is essential for establishing a functional network environment.
