Pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as the supervisor of taxes in Rouen , France. [ 2 ]
French polymath Blaise Pascal invented the mechanical calculator. [23] Called machine arithmétique , Pascal's calculator and eventually Pascaline , its public introduction in 1645 started the development of mechanical calculators first in Europe and then in the rest of the world.
Pascal invented his machine in 1642. In 1642, while still a teenager, Blaise Pascal started some pioneering work on calculating machines and after three years of effort and 50 prototypes [18] he invented a mechanical calculator. [19] [20] He built twenty of these machines (called Pascal's calculator or Pascaline) in the following ten years. [21]
Hamman Manus R mechanical computer, produced in Germany by the DeTeWe company between 1953 and 1959. A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment ...
This machine invented the principle of the modern computer and was the birthplace of the stored program concept that almost all modern day computers use. [52] These hypothetical machines were designed to formally determine, mathematically, what can be computed, taking into account limitations on computing ability.

A word processor (WP) [1] [2] is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features.. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers.
Blaise Pascal [a] (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, philosopher, and Catholic writer. Pascal was a child prodigy who was educated by his father, a tax collector in Rouen .
