Generations of Computers
In the history of computers, we often refer to the advancements of modern computers as the generation of computers. We are currently on the fifth generation of computers. So let us look at the important features of these five generations of computers.
1st Generation: This was from the period of 1940 to 1955. This was when machine language was developed for the use of computers. They used vacuum tubes for the circuitry. For the purpose of memory, they used magnetic drums.
2nd Generation: Here they advanced from vacuum tubes to transistors. This made the computers smaller, faster and more energy efficient. And they advanced from binary to assembly languages.
3rd Generation: The hallmark of this period (1964-1971) was the development of the integrated circuit.
4th Generation: The invention of the microprocessors brought along the fourth generation of computers. This was when we started producing computers for home use. Another important aspect is the development of higher computer languages like C++ and Java.
5th Generation: This is the present and the future of the computer world. The defining aspect of this generation is artificial intelligence. The use of parallel processing and superconductors are making this a reality and provide a lot of scope for the future.
