In systems analysis a prototype is a model of the system (or subsystem) under analysis [ 2 ]. A system can be anything from the food ordering system at a restaurant to the air traffic control system of a major airport. Prototypes of these systems can take many forms. They can be paper-based or computer-based.
A solvent is a substance which dissolves a solute. When a solvent dissolves into a solute, it creates a solution. If i pour salt into a cup of water. The salt is the solute because it's being dissolved and the water is the solvent because it is doing the dissolving.
A solute is what is dissolved in a solution eg. Salt and water. The solute in the solution is the salt as it has dissolved in water. There can be many different solutes in a sâ¦olution at one time. A cup of coffee contains many solutes as the coffee granules and the sugar have dissolved in the water, making these two solids solutes.
