"The Evolution and Function of Electronic Computers: From ENIAC to Modern PCs"
The Evolution and Operation of Electronic Computers A quarter of a century ago, discussing the Personal Computer (PC) was often met with skepticism. Computers were expensive—ranging from thousands to millions of dollars—occupied large spaces, and required trained teams to operate and maintain them. As a result, only governments and large institutions could afford them. Today, electronic computers are ubiquitous. Ordinary people can own, operate, and maintain them, and they are portable. Computers and ultra-small technological products have become the foundation of the information society. Early computers vs. modern personal computers --- 1. Development of the Electronic Computer The electronic computer is fundamental in designing and constructing modern information systems. It provides: High performance: speed, accuracy, reliability, and availability for complex arithmetic operations. Data storage: vast amounts of organized information accessible almost instantly.
