A Concise History of Computers, Smartphones and the Internet
The very first electronic computers were invented at the end of World War II. They were very large machines that could only be used in special air conditioned rooms. Today, almost everybody carries a computer in their pocket, in their mobile phone. How did all this come about in only 70 years? This book is for people who would like to know the answer to this question. It tells this exciting story, with a lot of pictures. This book is not a complete history, rather it is a concise history that covers the most important people, companies and inventions that led to where we are today. The first chapter covers the evolution of computer hardware - the physical machine. The second chapter focuses on the software - the programs that provide the instructions that tell the hardware what to do. The third chapter covers the most important data networks that were developed so that computers could communicate with each other, ending with the Internet which only became the dominant computer network after 1995. The last chapter on Smartphones traces its history from the discovery of radio waves in the late 19th century to the Apple iPhone. This book does not require a lot of technical knowledge about computers. People who are interested in learning more about how computers actually work can read the companion book “Understanding Computers, Smartphones and the Internet”, by Ernie Dainow.
Understanding Computers, Smartphones and the Internet
Most introductory books about computers are long, detailed technical books such as those used in a computer science course or else tutorials that provide instructions on how to operate a computer with little description of what happens inside the machine. This book fits in the large gap between these two extremes. It is for people who would like to understand how computers work, without having to learn a lot of technical details. Only the most important things about computers are covered. There is no math except some simple arithmetic. The only prerequisite is knowing how to use a web browser. As an alternative or adjunct to reading the book, you can watch a series of short videos by going to youtube.com and searching for “Understanding Computers, Smartphones and the Internet”. Only current day technology is covered. People who are interested in learning about how computers evolved from the earliest machines can read the companion book “A Concise History of Computers, Smartphones and the Internet”. While originally intended for people who are not in the computer field, this book is also useful for those taking a coding course or an introductory computer science course. Even people already in the computer field will find things of interest in this book.
Surviving in the Hi-Tech World - Memoirs of a life in computers
Surviving in the Hi-Tech World follows the many ups and downs of my years as a software developer in the high-tech industry, starting in the mainframe era. It provides a window into what it is like to work in the computer field. I worked for many different organizations, from academia and large companies to medium sized companies and several startups. The stories weave my work experience with explanations of the technology of the period. In the process it follows the revolutionary changes in computer hardware and software from large mainframes to personal microcomputers and the evolution of early networks into the global Internet. When I was a psychology student in university, I became interested in the possibilities of using computers to model and understand human thinking. I completed a Master's degree in Artificial Intelligence in Computer Science in 1970, but my interest in doing academic research shifted to an interest in building real world systems. My first job in computers was with Univac, the company that had built one of the first general purpose commercial computers. I switched jobs for many different reasons – sometimes because of interest and at other times because of necessity. Each chapter in the book covers the different jobs and places that I worked. My journey took me from Montreal to London, Glasgow, Wisconsin, Vancouver and Toronto. Each job has its own story as I progressed through a series of adventures. There are stories of people who became multi-millionaires and one who went to jail.
