Mark I

Mark I was designed in 1937 by a
Harvard graduate student, Howard H
Aiken to solve advanced mathematical

physics problems encountered by him in

his research. Mark I was originally called
the Automatic Sequence Controlled

Mark I Calculator by IBM and often referred to as

the Harvard Calculator when first installed in Cambridge in 1944. It started to
be known as Mark I as its successor machines were built.

A form of manual counting used was knotted strings, sometimes known as the quipu .
In their simplest form, knotted number strings are much the same as the simple tally
sticks. Counting with the use of knotted strings has been found all over the world.

The Inca Indians in particular were known for using the quipu.

ENIAC

The full form of ENIAC is Electronic Numerical Integrator And Computer , the

first programmable general-purpose electronic digital computer, built during
World War II by the United States. It was invented by John Mauchly and
