What is the difference between input and output?

Input and output, or I/O is the communication between an information processing system, such as a computer, and the outside world, possibly a human or another information processing system. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.

What are Input-Output tables (IOTs)?

Input-Output Tables (IOTs) describe the sale and purchase relationships between producers and consumers within an economy. They can either show flows of final and intermediate goods and services defined according to industry outputs ( industry × industry tables) or according to product outputs ( product × product tables).

Why do small engineering firms use the input-output model?

A small engineering firm uses the Input-Output Model after there are concerns with the hiring process. This example IPO Model was created to analyze and document the process. The Input-Output (IPO) Model is a functional graph that identifies the inputs, outputs, and required processing tasks required to transform inputs into outputs.

What are input-output accounts?

Input–output accounts are part and parcel to a more flexible form of modelling, computable general equilibrium models. Two additional difficulties are of interest in transportation work. There is the question of substituting one input for another, and there is the question about the stability of coefficients as production increases or decreases.
