Explain the 7 Layers of OSI.
Answer:
Layer 1: Physical layer
It represents all the electrical and physical specifications for devices.
Layer 2: Data link layer
It provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the Physical layer.
Layer 3: Network layer
The Network layer provides the functional and procedural means of transferring variable length data sequences from a source to a destination via one or more networks.
Layer 4: Transport layer
It provides transparent transfer of data between end users.
Layer 5: Session layer
It controls the sessions between computers. It connects, manages and terminates the connections between the local and remote application.
Layer 6: Presentation layer
It transforms data to provide a standard interface for the Application layer.
Layer 7: Application layer
It provides a means for the user to access information on the network through an application.
