Network 101 - 21st Century Presents

NEW TO NETWORKING?
Confused about some of the terms?
Our Networking 101 course covers topics like:
• The fundamentals of how data moves around the Internet (packets and packet-switching)
• The logic behind IP address schemes
• Public vs. Private IP addresses - What is NAT?
• What are dynamic IP addresses, DHCP reservations, and static IP addresses and when do you use them?
• What is DNS? - Briefly touch on VLANs and VPNs
• What are the basic components of a network and how do they fit together (cabling, Wi-Fi, managed vs. unmanaged switches, the role of the ISP)
• With all of these topics in mind, what is the role of the router, why is it considered the cornerstone of the network, and why is the router no longer simply a commodity?
• What should you expect from a great router in your customer's network?
