Introduction and the Application Layer - Discussion

Technology and Evolution (Graded)

As you will discover this week through your studies, communications have gone through some major changes throughout history. Explain how information systems from the 1980s differ from information systems today. What networking and communications changes were introduced in the past decade (2000s), and what were their implications?

Introduction and the Application Layer - Discussion

The Application Layer (Graded)

The textbook and lecture explain that there are four fundamental application architectures in use today: host-based architectures, client-based architectures, client-server architectures, and peer-to-peer architectures. Do some research in the DeVry Virtual Library (Under Course Home in the Student Resources section). Based on your research, what application architectures are most prevalent today? Under what architecture would you classify technologies such as virtualization, cloud computing, and Web-based applications? Last, what factors are involved in selecting the architecture that is right for your organization?
