All True or False Questions 1. In the introduction to networking module, we learned that the main reason we need networking is to allow software applications to Send/Receive data from other software applications (i.e. so that apps can talk to each other) T or F 2. Data networks move binary data (zeroes and ones) encoded as signals through transmission media between devices (or more precisely apps running on devices) T or F 3. Hosts (also known as end-points) can be...
