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? .0001pt;”>Week 1: Introduction and 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?
