Explain the OSI model and its varying layers?
OSI model is a reference model specified for how applications communicate over a network. An OSI reference is used to guide manufacturers and developers in the development of digital communication devices and software packages.
OSI model consists of different layers that include the following:
Physical Layer: This layer is in charge of sending and receiving digital data across a communication medium.
The Data Link Layer: this layer is in charge of moving data to and from the physical link. It's also in charge of data bit encoding and decoding.
The Network Layer is in charge of packet forwarding and providing network communication routing paths.
The Transport Layer: This is in charge of end-to-end network communication. It divides the data from the previous layer and passes it to the Network Layer, after which it verifies that all of the data has arrived at the receiver's end.
The Session Layer: The sender and receiver's connection is controlled by the session layer. It's in charge of initiating, sustaining, and synchronizing interaction between the sender and the receiver, as well as starting, ending, and managing the session.
Presentation Layer: Instead of sending raw datagrams or packets, the Presentation Layer works by displaying the data in an appropriate manner and data structure.
Application Layer: It serves as a connection point between the application and the network. It focuses on communication between processes and provides a communication interface.
