The computer hardware have five generations.
1) First generation (1946-1956)
2) Second generation (1956-1964)
3) Third generation (1964-1970)
4) Fourth generation(1970 –till date)
5) Yet to come
But there are many different opinions in the timeline of computer history.
1) First generation
The first generation starts by the invention of Vacuum tubes. The Ram made by the vaccum tubes. Also it was the convenient method of data storage. And IBM made pluggable module using vaccum tubes.
Examples : IBM 650
2) Second generation
Second generation starts by the invention of Transistors. Transistors cause to reduce the size of computer and other electronic devices.It need only less electricity power. Transistors also generate less heat during working. A transistor can work as a resister and also as a transmitor
Examples : IBM 7090
3) Third generation
Invention of IC’s(Integrated circuits) marked the third generation. IC s are made by silicon chips which contain multiple transistors. The third generation computers occupy less space than second generation. Speed of computers also increased
Examples : IBM 360\91
4) Fourth generation
Fourth generation started from the invention of Micro Processors. Intel created the First micro processor. Invention Micro processors led to the creation of Personal Computers
Examples: Dual Core processors, Intel 13,I7 etc…..
