Input is the term denoting either an entrance or changes which are inserted into a system
System

System is a set of interacting or interdependent entities, real or abstract, forming an integrated whole.The concept of an "integrated whole" can also be stated in terms of a system embodying a set of relationships which are differentiated from relationships of the set to other elements, and from relationships between an element of the se...

Systemics

 perspective, input is subjective and depends on how the system is used. In such sense, the same system can have different inputs in different applications.

In the case of a process description/model, input is closely connected with the concept output
Output

Output is the term denote either an exit or changes which exit a system and which activate/modify a process. It is an abstract concept, used in the model ing, system design and system exploitation....
. 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
Carrier

Carrier may refer to:In Science:* Carrier wave, a waveform suitable for modulation by an information-bearing signal* Charge carrier, an unbound particle carrying an electric charge...
 of a process x = g(p,y), where y is an input and x is an output.

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).
