Another way that prototypes are classified is by the fidelity of the prototype, or the degree to which the prototype represents the appearance and interaction of the system.[ 4 ] A low-fidelity prototype is one that is quickly constructed to depict concepts, design alternatives, and screen layouts.
A solution is a homogeneous mixture of one or more solutes dissolved in a solvent. 1  solvent: the substance in which a solute dissolves to produce a homogeneous mixture. 2  solute: the substance that dissolves in a solvent to produce a homogeneous mixture.
A solution is a mixture of one substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent. The solute is the substance being dissolved and the solvent is the part of the solution that does the dissolving. The solute is of molecular size. Examples of Solutions: * Two liquids that are soluble are said to be miscible in one another.
