Question

For the following system provide the input and output variables. Justify.

*One Gadget in your home

*An example of a socio-economic system

*One system that you are using as a part of your work

Answer 1

The question that you mentioned is is broad question. The input variable for a system means the variable brings some information to the system and output variable means it gives some information from the system.

Here i am describing the answer in accordance to your question.

(1) one gadget in your home

Let us consider Fan.The input to fan is electric supply. That is input variable is electric voltage. Output variable is speed of the fan.In between input votage and output speed there is a process in fan which is the conversion of electrical energy into mechanical energy.

(2)example of a socio economic system

As the name indicates socio economic system has both importance in social field and economic field. Let us consider a scenario of using super computers in prediction of stock price calculation. Here the input variable holds the data that we are supplying, it may be records of past 10 years stock prices, records of inflations happend etc. Super computer will do a computation based on our input variable which is the required process to be completed. The output variable contains the prediction of stock prices for the society.

(3)one syatem as part of your work

Suppose you are a student and as part of your work you are using a calculator to perform some mathematical calculations.

Suppose you are performing addition in calculator. For addition you need to supply two values. Therefore you have two input variables and they are holding the values that you entered. The output variable is the variable which holds the result of addition and displays it in calculator. Here addition and displaying results are processes that work on variables.

Hope it helps.
