answer the following questions on the world documentation feel free to ask when it is not clear.
- ‘Network security’ often used interchangeably with ‘cybersecurity’? Why? Do you agree? Why or why not – write 500 words.
- List and describe each of the layers of the TCP/IP Model. Also list each layer in the table below.
- List and describe each of the layers of the OSI Model.
- What is the difference between TCP/IP and OSI models?

- Wireless networks function on many of the same principles discussed in class. Study https://www.consumer.ftc.gov/articles/0013-securing-your-wireless-network and go through the steps to ensure that your home or a friends wireless network is secure. Provide here a log of the steps you took and explain why you took them.
- Create a brief ‘tip sheet’ to give to your friends and family on being secure on public WiFi networks (like on an airport). Along with tips, give a small explanation on the consequences of not taking security precautions on public networks.
