CORE DEFINITION

When the characteristics of two connected systems (such as the input and output of a circuit, or object code and a relational database) do not match, energy or information cannot be transmitted effectively, resulting in reduced efficiency and loss.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

When the characteristics of two connected systems (such as the input and output of a circuit, or object code and a relational database) do not match, energy or information cannot be transmitted effectively, resulting in reduced efficiency and loss.

Mismatch between source and load impedance causes partial reflection of energy, reduced transmission efficiency, and even damage to components, which are the consequences of mismatch.
