The History, Development, and Importance of Personal Computers
Overview
The personal computer was introduced in 1975, a development that made the computer accessible to individuals. Up to that time computers had been very large and expensive, operated mainly by big companies. The first modern computers were created in the 1950s and have a long theoretical and technical background. The use of computers has profoundly effected our society, the way we do business, communicate, learn, and play. Its use has spread to all literate areas of the world, as have communication networks that have few limits. The personal computer has inspired new industries, new companies, and created millionaires and billionaires of their owners. It has also changed the English language and refocused the power in many businesses from the men who procure the money to those who create the product.
Background
Human beings have devised many ways to help them do calculations. Before the creation of the modern large computer and its refinement, the personal computer, a number of discoveries and inventions were necessary. The decimal system, a binary mathematical system, and Boolean algebra are required to make computers work. The eighteenth-century discovery of electricity was also essential, as was the knowledge of how to use it in the mid-nineteenth century.
