History of Computers

ENG 121

The volume and use of computers in the world are so great, they have
become difficult to ignore anymore. Computers appear to us in so many ways that
many times, we fail to see them as they actually are. People associated with a
computer when they purchased their morning coffee at the vending machine. As
they drove themselves to work, the traffic lights that so often hampered us are
controlled by computers in an attempt to speed the journey. Accept it or not,
the computer has invaded our life.

The origins and roots of computers started out as many other inventions
and technologies have in the past. They evolved from a relatively simple idea or
plan designed to help perform functions easier and quicker. The first basic type
of computers were designed to do just that; compute!. They performed basic math
functions such as multiplication and division and displayed the results in a
variety of methods. Some computers displayed results in a binary representation
of electronic lamps. Binary denotes using only ones and zeros thus, lit lamps
represented ones and unlit lamps represented zeros. The irony of this is that
people needed to perform another mathematical function to translate binary to
decimal to make it readable to the user.

One of the first computers was called ENIAC. It was a huge, monstrous
size nearly that of a standard railroad car. It contained electronic tubes,
heavy gauge wiring, angle-iron, and knife switches just to name a few of the
components. It has become difficult to believe that computers have evolved into
suitcase sized micro-computers of the 1990's.

Computers eventually evolved into less archaic looking devices near the
end of the 1960's. Their size had been reduced to that of a small automobile and
they were processing segments of information at faster rates than older models.
Most computers at this time were termed "mainframes" due to the fact that many
computers were linked together to perform a given...
