The Three Generations of Computer:
First-Generation (1937 – 1946)
Clifford Berry and John Atanasoff assembled the primary electronic computerized PC called the Atanasoff-Berry Computer (ABC) In the year 1937. An electronic PC named Colossus was designed for the military in 1943. This PC gauges 30 tons and had about 18,000 vacuum tubes for processing. When this computer was turned on, lights in parts of the city of Philadelphia went off due to heavy load.
Second-Generation (1947 to 1962)
Back then, PCs used semiconductors rather than more solid vacuum tubes. In 1951, the first commercial computers were launched which was the widespread programmed PC known as UNIVAC 1. It was designed by J. Presper Eckert and John Mauchly.
The International Business Machines (IBM, in case you missed it) 650 and 700 series PCs gained prominence in 1953. In this age of computers, about 100 different PC programming languages have been created, and these computers had memory along with working frameworks.
Third-Generation (1963 to Present)
The creation of the incorporated circuit brought on the third era of PCs. With this kind of innovation, computers became more powerful and remarkable, and now they could run various programs simultaneously. In 1981, IBM manufactured a computer for home and office use.
Due to different enhancements in computer advancement, we have seen computers utilized in almost all activities of our life. It has evolved as a useful tool that will keep on upgrading in the near future and will become more powerful.
