NEGATIVE FEEDBACK Meaning and
Definition
-
Negative feedback refers to a regulatory mechanism in a system or process that strives to maintain stability by counteracting and reducing any deviations from a desired state. It is a type of information loop whereby the output of a system or process is monitored and compared with a set reference point or a desired outcome. When the output deviates from the desired state, the system triggers corrective actions to reduce the deviation and restore equilibrium.
In general, negative feedback works as follows: if the output exceeds the reference point, the system responds by producing an opposite effect, thus reducing the output back towards the desired level. This corrective response is aimed at stabilizing and maintaining the system within a narrow range.
In biological systems, negative feedback plays a crucial role in regulating various physiological processes such as body temperature, blood pressure, and hormone secretion. For example, when body temperature rises above the set point, negative feedback mechanisms kick in to induce cooling responses such as sweating or dilation of blood vessels to dissipate heat and bring the temperature back to the desired level.
Negative feedback is also extensively utilized in engineering systems, control systems, and electronic circuits to ensure their stability and prevent oscillations or over-corrections. It acts as a self-correcting mechanism, helping to maintain a steady state and optimize system performance.
Overall, negative feedback is a vital regulatory mechanism that operates in a wide range of natural and engineered systems, providing stability and control by minimizing deviations from a desired outcome.

Etymology of NEGATIVE FEEDBACK
The word "negative" in the term "negative feedback" originates from the Latin word "negativus", which means "denying" or "negating". It refers to the concept of reversing or dampening a particular process or outcome.
The word "feedback" comes from the combination of "feed" and "back", which first appeared in the 1920s. In this context, "feed" refers to providing input or information, while "back" indicates a reaction or response. Together, "feedback" refers to the process of returning part of the output of a system as input, enabling adjustments or modifications.
Thus, the term "negative feedback" is used to describe a type of feedback in which the system responds to a particular output or behavior by negating or dampening it, usually serving to stabilize or regulate the system.
