what are the Osi layers

Question

Accepted Answer

The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven layers.

The seven layers of the OSI model are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has a specific function and interacts with the layers above and below it.
The Physical layer deals with the physical transmission of data, such as cables and network interfaces.
The Data Link layer provides error-free transmission of data frames between nodes on a network.
The Network layer handles routing and logical addressing, allowing data to be sent across different networks.
The Transport layer ensures reliable delivery of data between end systems, providing error recovery and flow control.
The Session layer establishes, manages, and terminates connections between applications.
The Presentation layer handles data formatting, encryption, and compression.
The Application layer provides services directly to the end user, such as email, web browsing, and file transfer.
