Communication circuit, also known as communication path or communication channel, is the physical medium or electrical signal connection between two or more communication nodes. It is an important component of communication system.

In simple terms, communication circuit is the basic component of communication system, which establishes the connection between two or more communication nodes. It can be any physical medium, such as copper wire, coaxial cable, optical fiber, optical waveguide, or a wireless transmission such as microwave, radio frequency, satellite links, etc. The communication nodes can be two computers, two modems, or two networks.

In communication systems, a communication circuit is used to transmit digital signals in the form of electrical signals or optical signals. For example, in a data communication system, a communication circuit is used to transmit digital data between two computers. The circuit consists of a transmission medium, such as a copper wire or optical fiber, and a transmitter/ receiver, such as a modem, that converts the digital signal into an analog signal suitable for transmission over the transmission medium.

Communication circuits are also used in telephone networks, television networks, and other types of networks. In these networks, the communication circuit is used to connect the nodes in the network. This circuit carries the signals from one node to another. Depending on the type of network, different types of circuits are used, such as voice circuits, data circuits, video circuits, etc. Each type of circuit is designed to carry the specific type of signal.

Communication circuits can also be used to connect two networks. This type of circuit is often used in Internet Protocol (IP) networks. It connects two networks in a way that allows packets of information to be sent between the two networks. The packets are routed based on the IP address of the source and destination network.
