By trenanscott ·
I would like to learn more about the OSI model and the different levels that it goes through. Do you know of any good sites that have good information on this subject?

1. Application Layer
Allows applications to use the network. Handles network access, flow control, and error recovery.

2. Presentation Layer
Translates data into a form usable by the application layer. The redirector operates here. Responsible for protocol conversion, translating and encrypting data, and managing data compression.

3. Session Layer
Allows applications on connecting systems to establish a session. Provides synchronization between communicating computers.

4. Transport Layer
Responsible for packet handling. Ensures error-free delivery. Repackages messages, divides messages into smaller packets, and handles error handling.

5. Network Layer
Translates system names into addresses. Responsible for addressing, determining routes for sending, managing network traffic problems, packet switching, routing, data congestion, and reassembling data.

6. Data Link Layer
Sends data from network layer to physical layer. Manages physical layer communications between connecting systems.

7. Physical Layer
Transmits data over a physical medium. Defines cables, cards, and physical aspects.

Hope this helps!!!
