The document discusses the evolution of computers through five generations from 1940 to the present. The first generation from 1940-1956 used vacuum tubes, magnetic drums, and filled entire rooms. The second generation from 1956-1963 replaced vacuum tubes with transistors. The third generation from 1964-1971 saw the development of integrated circuits which increased computer speed and efficiency. The fourth generation from 1971 featured microprocessors which placed thousands of integrated circuits onto a single silicon chip. The fifth generation continues developing artificial intelligence applications like voice recognition.
2. Introduction To The Computer
First Generation - 1940-1956
The first computers used vacuum tubes for circuitry and
magnetic drums for memory, aking up entire rooms
3. Introduction To The Computer
Second Generation - 1956-1963
Transistors replaced vacuum tubes and ushered in the
second generation computer
4. Introduction To The Computer
Third Generation - 1964-1971
The development of the integrated circuit. increased
the speed and efficiency of computers
5. Introduction To The Computer
Fourth Generation - 1971
The microprocessor brought the fourth generation of
computers, as thousands of integrated circuits we rebuilt
onto a single silicon chip. A silicon chip that contains a CPU
6. Introduction To The Computer
Fifth Generation - Present and Beyond
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
