Programming is a way of organizing a task so that it is replicable by something elsea computer. If you have ever given someone directions, or written down a recipe, you have some experience with programming. Learning more about programming will help you develop the skills of thinking systematically about a task and breaking it down into manageable pieces, which can be applied in many disciplines. This class contextualizes the task of programming by focusing on media, such as images, audio, and interactive systems. By doing so, we hope to put programming in a relevant context. For example, iteration is a programming concept that is essential to creating negative and grayscale images. You will learn algorithms for blending two images together and how to hierarchical relationships are used to organize elements of a user interface. This introductory course has no particular prerequisites and is primarily designed for non-computer science students.

This course provides an overview of the evolving field of cybersecurity, with an introduction to cybersecurity standards and law. Students will learn about common cyber attacks and the techniques for identifying, detecting, and defending against cybersecurity threats. They will also gain a basic understanding of personal, physical, network, web, and wireless security, as well as a foundation for more advanced study of cybersecurity.

Cryptography is essentially the science of writing in secret code.  In data and telecommunications, cryptography has specific security requirements, such as authentication, privacy or confidentiality, integrity, and non-repudiation.  To meet these security requirements, we employ secret key (or symmetric) cryptography, public-key (or asymmetric) cryptography, and hash functions. In the first part of the course, we will review a number of different ciphers that were used before World War II.  These ciphers would be easily broken nowadays, since cryptography has advanced quickly over the past couple of decades with the advent of modern computers.  We will cover block cipher algorithms and describe the advanced encryption standard for a symmetric-key encryption adopted by the U.S. government.  We will also learn about the important MD5 and SHA-1 hash functions as well as the message authentication code. This course will focus on public key cryptography, which is best exemplified by the RSA algorithm (na…

This course is designed for the novice who has little or no word processing experience.  The course provides an introduction to word processing.  You will explore word processing skills while also learning to create a basic business letter and a business memo.  Although the resources in this course use Microsoft Word 2010, it should be noted that all of the basic skills and tasks that you will be asked  can be done on any word processing program.  If you stay flexible enough in your own word processing program to search out the commands and icons on whatever software you are using, you will succeed.  The most current version of Microsoft Word was selected, because it would be most beneficial to the job seeker.  In addition most colleges, universities, and some public libraries are using a newer version of Word.  You can complete this course using any word processing software, but if you are using an older version of Word, you may also want to seek out a resource where you can interact with the newer v…

This course will provide you with a comprehensive introduction to spreadsheets. The course is designed for first-time users with very little or no exposure to the subject. For this course, you will use Microsoft Excel as the software. The course will explore the following fundamental topics: an introduction to spreadsheets, terminology in Excel, components of a spreadsheet, what a cell consists of, and the creation of a spreadsheet for practical use.  You will examine sample files, videos, and books that will enable you to gain practical knowledge about spreadsheets that can be used in daily life, either at work, school, or home.

This class is intended for students who have a basic understanding of spreadsheets and are now ready to delve deeper into formatting, formulas and functions, multi-page spreadsheets, charting data, creating tables that have database features, and be introduced to pivot tables. This class was designed to be an active, hands-on class. You will be creating Excel® spreadsheets and have files to open and follow along as you progress through the units. This class is not intended for a specific occupation or activity, but when you are finished with this class, you will be able to use Excel® in a variety of circumstances to format and manipulate numerical data. Although the resources in this course use Microsoft Excel® 2010, it should be noted that all of the skills and tasks that you will be asked to complete can be done in any version of Excel®. If you stay flexible enough in your thinking and search out the commands and icons on whatever software you are using, you will succeed.

This course presents material in discrete mathematics and computation theory with a strong emphasis on practical algorithms and experiential learning. Discrete mathematics, also called finite mathematics or decision mathematics, is the study of mathematical structures that are fundamentally discrete in the sense of not supporting or requiring the notion of continuity. Objects studied in finite mathematics are largely countable sets such as integers, finite graphs, and formal languages. Concepts and notations from discrete mathematics are useful to study or describe objects or problems in computer algorithms and programming languages. The CDM course is currently under development and we are making the course available while it is under development. Only one of the planned fifteen modules is currently available. The module on Groups that is currently available would appear mid-way through the complete course.
