5 Generations of Computers
FIRST
GENERATION
a glass tube surrounding a vacuum (an area
from which all gases have been removed).
What makes it interesting is that when
electrical contacts are put on the ends, you
can get a current to flow though that vacuum.
Thomas Edison noticed this first in 1883
ENIAC
First generation computers relied on machine language to perform operations,
and they could only solve one problem at a time. Input was based on punched
cards and paper tape, and output was displayed on printouts.
UNIVAC and ENIAC computers are examples of first-generation computing
devices. The UNIVAC was the first commercial computer delivered to a business
client, the U.S. Census Bureau in 1951.
