Networks, and the technology behind networking, help us connect to the world around us. Through following multiple protocols, we’re able to use physical technologies to exchange a massive amount of information every single day.
To review, we’ve:
- Discussed the difference between Local Area Networks (LAN), Campus Area Networks (CAN), and Wide Area Networks (WAN)
- Introduced the OSI conceptual model of the 7 layers of networking, including:
- Physical Layer
- Data Link Layer
- Networking Layer
- Transport Layer
- Session Layer
- Presentation Layer
- Application Layer
- Introduced the TCP/IP model, also known as the Internet protocol suite that revolves around TCP and IP
- Learned about essential protocols like DNS, HTTP, and email protocols
- Learned about SSH, SMB, and FTP protocols that are important for accessing specific resources securely
While networking technology has helped connect people all throughout the world, it has also created new risks. Only by understanding network architecture more and more can we make educated decisions on network security!
