The Computer Information Systems (“CIS”) textbook used for the first few weeks of class is an open resource from Wikibooks (where its full title is Introduction to Computer Information Systems). At this stage it is still a work in progress, and, as such, is not fully complete and has not been thoroughly edited. It has been selected because it provides the basic information about rapidly changing topics that students need in order to be successful in the course. In addition, as an open resource it can be inserted directly into our class and students can download the entire text at no charge. The following correction to Chapter 2, p. 23 are provided, from the source shown below. P. 23 is supposed to have a Tera, Peta, Exa, Zetta, and Yotta chart, instead it shows bit shifting

Pg 24 erroneously writes ” In the decimal system each digit is raised by ten so that the first column equals 1 (10^1) or ten raised to the zero power, the second column equals 10 (10^2) or ten raised to the first power, the third column equals 100 (10^3) or ten raised to the third power and so on.” It should state “In the decimal system each digit is raised by ten so that the first column equals 1 (10^0) or ten raised to the zero power, the second column equals 10 (10^1) or ten raised to the first power, the third column equals 100 (10^2) or ten raised to the third power and so on.”
