Answer 1

The correct option is A First generation

First generation machines are characterised by electronic tube circuity, delay line, rotating or electrostatic memory.

The two notable machines of this era were the UNIVAC and ENIAC machines – the UNIVAC is the first every commercial computer which was purchased in 1951 by a business – the US Census Bureau.

The vacuum tube was invented in 1906 by an electrical engineer named Lee De Forest (1873–1961). During the first half of the twentieth century, it was the fundamental technology that was used to construct radios, televisions, radar, X-ray machines, and a wide variety of other electronic devices.
