Chapter 6 is about data communications-computer network. First, we learned about a communication with some tools. We colud write down out messase and give them each other. Then, we learned about a modem. Modems are the great tools for communicatind each other, but they were slow. People discovered internet.
Through this lesson, I could learn what a data communication is, and hoe it works.
