World’s First Computer – We have come a long way
The ENIAC (Electronic Numerical Integrator and Computer) made history as the first computer in the world (which was electronic programmable).
Development of the computer completed in 1945, and the computer entered service in December of that year.
ENIAC could displace the computational power of 2,400 human beings at a cost of $500,000.
ENIC relied on octal-base radio tubes to function. However, these tubes constantly burned out on a daily basis and required replacement.
This means that ENIAC ran about 50% of the time and experienced downtime for tube replacements otherwise.
More specialized and durable tubes eventually became available, leading to failures every one to two days.
Clearly technology has come a long way!
