Physical Layer

## Encounter (E)

• Key Takeaways:
  • Serves as the foundation for data communication within a network.
  • Primarily concerned with the transmission of raw data bits over a physical medium.

## Note (N)

• The Physical Layer of the OSI Model is responsible for the actual physical connection between devices, managing the way raw bits are placed onto and retrieved from the network medium.

## Connect (C)

• Related Notes:
  • Networking Fundamentals
  • OSI Model Overview
  • Bit Rate and Baud Rate
  • Types of Cables and Connectors

## Organize (O)

• Categories/Themes:
  • Networking
  • Communication Protocols

## Develop (D)

• Expanded Details:
  • The Physical Layer is the lowest layer in the OSI Model.
  • It interfaces directly with the network medium and ensures that when one side sends a 1 or 0, the other side receives the same value.

## Express (E)

• Share by:
  • Creating a simplified infographic that explains the role of the Physical Layer in data transmission.
  • Writing a blog post to demystify the functions and responsibilities of the Physical Layer.
  • Discussing the importance of the Physical Layer in a networking study group or online forum.
