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 specific type of mixture where one substance is dissolved into another. A solution is the same, or uniform, throughout which makes it a homogeneous mixture. It does not scatter a beam of light. 2  Solute-The solute is the substance that is being dissolved by another substance. 3  In the example above, the salt is the solute. 4  Solvent-The solvent is the substance that dissolves the other substance. 5  In the example above, the water is the solvent.
