This is an introductory text for a basic computer literacy course. We have tried to include all of the material necessary for an introductory computer literacy course, but, in order to keep a low price for our students, we have attempted to include ONLY what would be important in such a course.

Networks and Internet: Internet development, Internet services (WWW, e-mail, FTP, ... ), e-commerce, Internet architecture (HTML, TCP/IP, routers, servers, ... ), Social issues, Security, Net neutrality.The 2020 edition has several new topics and several topics from earlier editions have had information significantly updated. These topics include: virtual reality and haptic technology, smart tv's, video-telephony, VPN's, neural networks, social networks in politics, dark web, WIFI encryption, social engineering.

This is an introductory text for a basic computer literacy course. It was written because we found that most of the available texts were extremely expensive (up to and over $150.) We felt that this was, not only excessive, but also counterproductive. Very few students would be likely to buy this kind of text at that price.We have tried to include all of the material necessary for an introductory computer literacy course, but, in order to keep a low price for our students, we have attempted to include ONLY what would be necessary for such a course.
