Layered computer design focuses on computer design. It uses top-down, layered approach to design and also to improve computers. A computer is designed layer by layer, starting with top conceptual layer and ending with bottom layer, complete design. A layer is implemented by the layer below. There are numerous possibilities to implement a layer. To decide, design goals are used: speed, size, cost, weight, reliability, power consumption, flexibility, expendability and compatibility.
