Read the following passage

The question “Who invented the computer?” is not a

simple one. As a computer consists of many parts, each part can
be considered a separate invention. Therefore, many inventors
have contributed to the invention of the computer.

The root word of ‘computer’ is ‘compute’. The word ‘compute’

comes from the Latin word ‘computᾶre’ which means ‘to count’.
Therefore, ‘compute’ means ‘to count’ and ‘computer’ means ‘a person
who counts’ or ‘ a calculation device’. Many people consider the
abacus, first used by the Chinese about 1000 years ago, to be the first
computer in the world.

Later, the first automatic calculator was invented in 1642 by a French
mathematician, Blaise Pascal. It was considered the first true
computing machine. In 1939, the first digital computer was created by
an American mathematician and physicist, John V. Atanasoff. After that,
better computer models were made.

Multiple Choice

What is an abacus?

It was not until the early 1960s

that engineers were able to build high
speed computers with large
memories because of the
development of the integrated circuit.
This eventually led to smaller
computers being made in the early
1970s. The personal computers were
only introduced in 1975, the same
year Miscosoft Corporation was
founded. At first, the sales of these
personal computers were not
encouraging. Six years later, the
sales skyrocketed when IBM
introduced its personal computers
called ‘PC’. In 1981, the first
commercial laptop was introduced,
but it was not user-friendly because it
did not have battery.

Some significant inventions were also

made to complement the computer. For
example, the computer mouse was invented
in 1962. It was called ‘the mouse’ because
the wire that comes out from the mouse
resembles the tail of a mouse. The year 1969
saw the birth of the original Internet. The
original 8-inch floppy disc was invented in
1969 with limited storage capacity, but,
smaller diskettes were produced after that. In
1996, the USB flash drive with higher storage
capacity was invented. It is also known as
the ‘thumb drive’ because its size is similar to
the size of a human thumb.

Today, the computers we see have

actually undergone a tremendous evolution.
Along with it, many computer peripherals
were also invented. One thing for sure is that
better and improved computers will be
created in the future to revolutionise and
make our life easier.
