1. Physical Layer: Deals with physical connection and transmission of raw bitstreams.
2. Data Link Layer: Handles error-free data transfer between connected devices.
3. Network Layer: Responsible for routing and addressing.
4. Transport Layer: Provides end-to-end data transfer services, including flow control and error recovery.
5. Session Layer: Establishes, maintains, and terminates communication sessions between applications.
6. Presentation Layer: Handles data formatting and encryption/decryption.
