- 7.4: The Network as a Platform Converged Networks
- There are different types of networks, converging networks, and separate networks. Separate networks do not allow different devices connected to different networks to communicate because they aren't interconnected. However, converged networks are built to convey data among various devices connected to the same network.
- 7.5: The Changing Network Environment Network Trends
- Technology is constantly evolving, and new network trends influence organizations and consumers.
