Learning Objectives

By the end of this lesson you will be able to:

• Explain how all components of a network function together to deliver packets from one device to another device, which could be on the other side of the world.
• Determine whether an IP address is public or private.
• Understand how the IPv4 address shortage is solved with NAT and IPv6.
• Calculate the network address and subnet size given the address of one device on the network, and the subnet mask.
• List the layers in the OSI Model
• Describe how data moves down the layers in the OSI Model in a process called Encapsulation
• Describe how data moves up the layers in the OSI Model in a process called Decapsulation
• Diagram how data moves from the sending device and across a network to the target device
• Recommend an appropriate switching architecture for a particular network size.
• Use the Wireshark network analysis tool to extract address, FQDN, and DNS information from real network packet transmissions
• Explain how the DNS server resolves an FQDN query to an IP address
• Explain how load balancing works and the different ways of balancing the load of incoming network traffic
