COMPUTER GENERATIONS
After these early calculating machines, the present computer took its shape in five
generations.
First Generation (1940s)
Many computers were part of the first generation computers.
MARK-I
In 1944, Prof. Howard Aiken built the first electro-mechanical computer called
Mark-I. It used punched cards for input and a typewriter for output. Mark-I was
more reliable than the early electronic computers.
ENIAC
The Electronic Numerical Integrator and Computer (ENIAC) was the first electronic
general-purpose digital computer. This computer was created in 1946 by John
Mauchly and Presper Eckert. It had over 18,000 vacuum tubes and was 1,000
times faster than the Mark-I. ENIAC consumed nearly 200 kW of power.
Boost Bits
The first electronic computer ENIAC weighed more than 27 tons and took up
1800 square feet.
