55 Fifth Generation Computers ???? Will be much smaller and faster than 4th Generation Greatly increased data storage capability Will most likely have light, easily transportable display capabilities May be built into clothing

56 Fifth Generation Computers Fifth Generation - Present and Beyond: Artificial Intelligence Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self- organization. artificial intelligencevoice recognition parallel processingQuantum computationnanotechnologynatural language
