Invention of electricity 🎇
The invention of electricity was created on 20 th century.
Curiosity : William Gilbert invented the word "electricity" -
Period: to
1 st generation 🧨
On February 15, 1946, the ENIAC ( Electronic Numerical Integrator Anol Calculator), the first electronic computer, was presented in the United States.
The 1 st generation computers use vacuum- tubes to carry data in the form of electronic signals.
The 1 st generation was very large, expensive and required a huge amount of electricity -
Period: to
2 nd generation 🎆
The second generation is made by transistors
Are much smaller, faster, and cheaper.
The second generation of computers replaced vacuum tubes with transistors. That's why second-generation computers are smaller and use less electricity than the previous generation. -
Period: to
3 rd generation ✨
Are made by integrated circuits.
Integrated circuits made computers smaller, cheaper and faster than 2 nd generation.
Less electricity and Fewer mistakes.
3 rd generation computers emerged with the development of integrated circuits in which thousands of electronic components are placed in miniature integration. -
Period: to
4 th generation 🎊
Time: 1975 - Present
Use microprocessors => small silicon chip with thousands of circuits.
The 4 th generation of computers are portable, cheaper, and smaller. They use less electricity and produce less heat. The small size of the chips made possible the creation of personal computers.Today's technologies allow hundreds of thousands of electronic components to be stored on a microchip. -
5 th generation 🎉
Time: 2022 - Future
5 th generation computers are the most advanced computers.
Scientists are developing.
They can " think" on their own " artificial intelligence"
