Day 31. Describe the Purpose and Functions of Various Network Devices

This first exam topic expects you to know the names and general functions of network devices. This is similar to something you might tell your friend at lunch if he or she asked for a 5-minute explanation of the computer lab at the library. As soon as you know the names of the devices, Days 30 and 29 look at their language (protocols). Chapters 1 and 3 of CCNA Discovery 1 describe network devices and their functions.
