FIRST GENERATION COMPUTERS •During the period of 1940 to 1956 first generation of computers were developed. • The first generation computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. • The vacuum tube was developed by Lee De Forest. A vacuum tube is a device generally used to amplify a signal by controlling the movement of electrons in an evacuated space.
FIFTH GENERATION COMPUTERS • 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.
