Study Notes
TCP/IP Layers
- Comprises four distinct layers: Link Layer, Internet Layer, Transport Layer, and Application Layer.
- Each layer has specific functions and protocols that facilitate communication over networks.
Application Layer
- Provides a means for applications to access communication services from lower layers.
- Defines protocols for data exchange between applications, ensuring interoperability between different systems.
Transport Layer
- Offers communication services to the Application layer, enabling session and datagram services.
- Ensures reliable or unreliable delivery of data, depending on the chosen protocol (e.g., TCP for reliable, UDP for faster, unverified transfer).
Internet Layer
- Handles crucial functions like addressing, packaging of data, and routing packets through different networks.
- Ensures that data packets reach their correct destination across diverse network architectures.
Network Interface Layer
- Responsible for the physical transmission of TCP/IP packets over the network medium.
- Involves placing outgoing TCP/IP packets onto the network and receiving incoming packets, bridging the gap between the data link and upper layers.
