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 liquid mixture (or a compound) in which a solute gets easily dissolved in a solvent. Usually, Solute is the smaller component of the solution which gets dissolved in the larger component, Solvent. Edit: Example- in Sugar solution, Sugar is the Solute and Water is the Solvent.
