TEXT 1
The word "computer" was first recorded as being used in 1613 and was originally used to describe a human
who performed calculations or computations. The definition of a computer remained the same until the end
of the 19th century when people began to realize machines never get tired and can perform calculations much
faster and more accurately than any team of human computers ever could.
In 1822, Charles Babbage began developing the Difference Engine, which was considered to be the first
automatic computing engine. It was capable of computing several sets of numbers and making hard copies of the
results. Unfortunately, because of funding he was never able to complete a full-scale functional version of this
machine. In June of 1991, the London Science Museum completed the Difference Engine Nº 2 for the bicentennial
year of Babbage's birth and later completed the printing mechanism in 2000.
