Welcome Back!
This morning we will begin with a review of the OSI Model, an opportunity to retake chapter 3.
We will review Binary and hex conversions and end with a round of subnetting.
We are skipping around the curriculum a little bit, but this is a necessary component of the SkillsUSA Internetworking Competition. Although Connor is the only one competing, you will all need to know this information.
Objective:
- Make sure we have a concrete understanding of the OSI Layers
- Successfully convert binary, hexadecimal and decimal
- How to identify reasons t use a subnet mask
- How to distinguish betweena default subnet mask and a custom subnet
- What given requirements determine the subnet mask, number of subnets and useable hosts
- How to use the ANDing process to determine if a destination IP address is local or remot
- How to identify valid and invalid IP host addresses based on a network number and subnet mask
