Answer:
According to school books and google there are 5 generations of computers, namely:-
Vacuum Tubes
Transistors
Integrated Circuits
Microprocessors
Artificial Intelligence
So, firstly Vacuum Tube computers. These were a huge computers, extremely slow, inefficient and heat producing. It had to be programmed in binary language and only basic problems could be solved.
Transistors, they were a better version of Vacuum Tube computers. Still heaters, but comparatively cheaper, faster and smaller.Assembly language was used to program them, and some versions of high level language was also being developed in this period. Also, today’s microprocessors contain lacs of microscopic transistors.
IC’s, a transistor computer only but quite a bit smaller, much more faster and cheaper, on a Silicon chip. An extremely popular tech region in California is named Silicon Valley. These were the first computers using a keyboard and monitor, which really was a great leap from punching machines and prints.
Microprocessors, INTEL! So, it basically was lacs of transistors, memory and control structures in 1 square inch OR in our palms. It was one of the biggest revolutions. Faster, cheaper and mainly FEASIBLE.
NOW, AI. This generation is not mature enough yet to come in consumer hands. BUT, its a machine that can learn things on its own. Basic examples which we use on a smaller basis is Siri and Google Assistant, our own Personal Assistants. Robots and a lot of revolutionary tech can be the derivatives of Artificial Intelligence.
Hope this makes you understand generations of computers a bit better!
