1943

• The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946.

• It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons.

 November 1953

A transistor computer, now often called a second generation computer, is a computer which uses discrete transistors instead of vacuum tubes. The first generation of electronic computers used vacuum tubes, which generated large amounts of heat, were bulky and unreliable.

how long apart were these two computers

• 10 years

• 20 years

• 30 years

• 40 years

• 50 years

1965-1971

• The period of third generation was from 1965-1971. The computers of third generation used Integrated Circuits (ICs) in place of transistors.

• A single IC has many transistors, resistors, and capacitors along with the associated circuitry. ... This development made computers smaller in size, reliable, and efficient.

1971-1980

• the period of fourth generation was from 1971-1980. Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits.

• VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.

how do you like these four computers so far from the ENIAC to the VLSI? I like the VLSI it looks sorta like a real computer in 2020

1982

The Fifth Generation Computer Systems (FGCS) was an initiative by Japan's Ministry of International Trade and Industry (MITI), begun in 1982, to create computers using massively parallel computing and logic programming.

2015

1, 2015 – Today Intel Corporation introduced the 6th Generation Intel® Core™ processor family, the company's best processors ever. The launch marks a turning point in people's relationship with computers

2016-now

Using improved memory technologies and energy-efficient chipsets, they work faster and use less energy than any previous Intel CPUs. The 7th generation Core i3, Core i5 and Core i7 desktop processors consume as little as 35W of power – with even the top-end CPU consuming a mere 95W.

so the world has created a lot of computers from ENIAC to Intel core hope someday we can create floating computers
