Part I of this book will cover the history of computers as well as search engines, word processors, Wi-Fi, texting, video games, and telecommunication systems. It will discuss some of the competition between individuals and the rivalries between companies such as between IBM (and IBM-compatible or clone companies) and Apple with the Macintosh computer. Although many people and companies were involved at the beginning of these innovations, IBM, Bell Labs, and Apple’s Steve Jobs are the most prominent names remembered. This book is by no means a complete collection of technological history; there are many other great inventors who contributed to the personal computer (PC) and other technologies. We will review many of the main ones.
