ENIAC— The First Electronic Computer
Electronic Numerical Integrator And Computer,
was the first electronic general purpose digital
computer built in 1946 by John Mauchly and
Presper Eckert. It contained over 18,000 vacuum
tubes and was 1000 times faster than Mark-I.
ENIAC consumed almost 200 kw of power.
ENIAC
UNIVAC
UNIVAC or Universal Automatic Computer, was
another successful invention of John Mauchly
and Presper Eckert in 1951, which could handle
both numeric and textual information.
The UNIVAC had 5200 vacuum tubes.
UNIVAC
Features of First Generation Computer
Huge in size.
Very expensive.
Made up of vacuum tubes.
Second Generation (1950s)
Vacuum tube
After 1955, use of transistors and magnetic tapes
changed the image of the electronic computer.
During this period, the major computer manufacturers
began to offer a range of accessories such as: Page
Printers, Cathode Ray-Tube display, Card Feeders, etc.
Magnetic tape
Features of Second Generation Computer
Made up of transistors.
Magnetic tapes were used to store data.
Small in size and less expensive than the first generation
computer.
Faster and reliable. Transistor
Third Generation (1960s)
In the third generation, the invention of Integrated Circuits
(IC) led to smaller-sized computers with better functioning
and more storage. Integrated Circuits
