What is a basic characteristic of wire communication?

Wire communication fundamentally relies on the transmission of information through a physical medium, such as copper wires or fiber optic cables. This characteristic distinguishes it from other forms of communication that may not require a tangible connection, such as wireless communication, which can occur through airwaves without the need for a physical link. The physical connection allows for the reliable transfer of signals over distances, making wire communication a stable and effective means of communication in various applications, including telephone systems and the internet. The presence of this physical link is what makes wire communication possible, as the information is actually carried along these wires, ensuring its integrity during transmission.
