Hi, welcome to the term of the day: the OSI Network model, what’s it consist of?
Layer 1: the physical layer, providing a physical network connection, defining the electrical and physical characteristics
Layer 2: the datalink layer, which creates a point-to-point connection between network endpoints, receives and sends data to and from the network layer
Layer 3: the network layer, responsible for routing data between network endpoints
Layer 4: the transport layer, ensuring delivery and quality-of-service
Layer 5: the session layer, which creates, maintains, and terminates sessions between endpoints
Layer 6: the presentation layer, converting data streams into formats that can be handled by the lower layers
and Layer 7: the application layer, providing access to the services provided by the lower layers
