A communication system that does not allow an interchange between the message source and the receiver is said to be a one-way or "simplex" communication setup. One that does allow an interchange is a two-way or "duplex" setup. Noise is an important concept in communication theory. Noise is defined in communication theory as any signal that interferes with the message being sent and is an undesired disturbance in a communication system. Radio static is a form of noise. Dirt on a camera lens is noise also.
Dirt on a camera is static.
A communication system is a “complex” communication setup.
Radio wave is a form of noise.
If there is dirt on a camera lens, it is also noise.
