Period: to
1940-1956
The first computer systems used vacuum tubes for circuitry and magnetic drums for main memory, -
Second Generation (1956-1963) Transistors
The transistors was invented in 1947 but did not see widespread use in the computers in 1950, his function was replace vacuum tubes and ushered in the second generation of computers -
First Geeration 1940-1956 Vacuum Tubes
The UNIVAC was created and he was the first commercial computer delivered to a business client in 1951 -
Second Generation 1956-1963 Transistors
Though the transistor still generated a great deal or heat that subjected the computer to damage, it was a vast improvement over the vacuum tube -
Second Generation (1956-1963) Transistors
Second generation has binary machine language to symbolic
Early versions of COBOL and FORTRAN these was the first computers that stored their instructions in their memory -
Second Generation 1956-1963 Transistors
The first computers of this generation were developed for the atomic energy industry -
Third Generation (1964-1971) Integrated Circuits
The development of the integrated circuit was the hallmark off the third generation of computers. -
Third Generation 1964-1971 Integrated Circuits
In the third generation the users interact with keboards and monitors and interfaced with an operating system. -
Fourth Generation (1971- Present) Microprocessors
The Microporocessor bought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip -
Fourth Generation 1971-Present Microprocessors
In 1981 IBM introduced its first computer for the home user
In 1984 Apple introduced the Macintosh -
Fifth Generaton (Present and Beyond) Artificial Inteligence
Fifth Generation computing devices, based an artificial inteligence, are still in development -
Fifth Generation(Present and Beyond) Artificial Inteligence
The goal fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization
