The Development of Personal Computers
The history of the computer goes back hundreds of years. From the abacus through the modern era the evolution of computers has involved many innovative individuals. It was out of this desire to innovate many fascinating tabulating machines developed. The modern computer, therefore, evolved from an amalgamation of the genius of many individuals over a long period of history. Many people shaped the world by making the efforts to develop technology.
An early counting machine (and relative of the computer) can be traced back to 3000 BC. This device is known as the abacus. Although ancient, the abacus is not archaic. It is still used in math education and in some businesses for making quick calculations (Long and Long 33C). This ancient device represents how far into history the desire of humans to use a machine for calculations goes.
Another early relative of the computer was created in the seventeenth century by Blaise Pascal, a French mathematician (Long and Long 33C). Pascal was born in Clermont-Ferrand on June 19, 1623 and his family settled at Paris in 1629 (Fowlie). In 1642 the young prodigy developed what is now known as "Pascal's Calculator" (or the "Pascaline") to speed calculations for his father, a tax collector. Numbers were dialed on metal wheels on the front of the machine and the solution appeared in windows along the top (Kindersley). The "Pascaline" used a counting-wheel design (Long and Long 33C). "Numbers for each digit were arranged on wheels so that a single revolution of one wheel would engage gears that turned the wheel one tenth of a revolution to its immediate left" (qtd. in Long and Long 33C). All mechanical calculators used this counting- wheel design until it was replaced by the electronic calculator in the mid-1960s (Long and Long 33C). Pascal's Calculator, however, was only the first step between the abacus and the computer.
