Input is the term denoting either an entrance or changes which are inserted into a system and which activate/modify a process. In Semiotics, denotation is the surface or literal meaning encoded to a signifier and the Definition most likely to appear in a Dictionary System (from Latin systēma, in turn from Greek systēma is a set of interacting or interdependent Entities, real or abstract It is an abstract concept, used in the modeling, system(s) design and system(s) exploitation. Scientific modelling is the process of generating abstract, conceptual, Graphical and or mathematical models. It is usually connected with other terms, e. g. , input field, input variable, input parameter, input value, input signal, input device and input file. An input device is any Peripheral (piece of Computer hardware equipment used to provide data and control signals to an information processing system (such as a A file format is a particular way to encode information for storage in a Computer file.

Overview
From the most general systemics perspective, input is a subjective concept and depends on how the system is used. Systemics is the emerging branch of Science that studies Holistic Systems It tries to develop logical mathematical engineering and philosophical paradigms In such sense, the same system can have different inputs in different applications.
In the case of a process description/model, the concept input is closely connected with the concept output. Output is the term denoting either an exit or changes which exit a System and which activate/modify a Process. Here, what enters is called input and what exits is called output.
Example: For an abstract system A(x,y,p), where x,y are variables and p is a parameter, x may denote input (variable) and y may denote the output for a process: y = f(p,x), but, for another goal/(system application), the system A can be the carrier of a process x = g(p,y), where y is an input and x is an output. A goal or objective consists of a projected state of affairs which a Person or a System plans or intends to achieve or bring about — a personal or
Usually, in the modeling of a problem/process, input are these variables which are known and output are those unknown to us yet.
In recognition that the quality of the input can be crucial to the value of the output, a famous saying teaches us "Garbage IN, Garbage OUT" (GIGO).
