 Welcome back. Congratulations on completing Unit 5. You're almost at the finish line, but you still have one more unit to go. We just learned about software development methodologies in programming languages. Each of these provides the details of a software development system from concept to a tangible software application. In Unit 6, you will learn more about the concept of globalization, identify issues in a global economy, learn about Nelson's three stages of the digital divide, define intellectual property, describe future trends in information systems, and the ethical and legal implications of information systems. As you move through each section of Unit 6, start to think about the final exam, which is a comprehensive test of the entire course. Chapter 11 of your textbook covers globalization and the digital divide. Globalization is the integration of goods, services, and culture among nations of the world. Globalization is not a new thing. However, advances in telecommunication and transportation have enhanced and accelerated it. Globalization has inspired the Network Society, published in 1996 by social sciences researcher Manuel Castiles. Castiles identified new ways in which economic activity was being organized around the networks that the new telecommunication technologies provided. As the internet continues to make its way across the globe, it is also developing a separation between those who have access and those who do not. This is known as the digital divide. In 1992, the ACM code of ethics and professional conduct began to focus on issues involving the digital divide that could prevent certain categories of people from receiving adequate access to the wide variety of resources offered by the technology. Unit 6 is the last unit of this course. Be sure to take notes in preparation for the final exam, and we'll see you here again for a final wrap up.
