applications of OSI layers

Question

Accepted Answer

The OSI layers are used to define the different functions of a network communication system.

The OSI model consists of 7 layers, each with specific functions.
Application layer (Layer 7) handles high-level protocols, such as HTTP and FTP.
Transport layer (Layer 4) ensures end-to-end communication and error-checking.
Network layer (Layer 3) deals with routing and forwarding of data packets.
Data link layer (Layer 2) manages the physical transmission of data.
Physical layer (Layer 1) defines the hardware and transmission media.
Each layer communicates with the adjacent layers to facilitate data transfer.
The OSI model helps in troubleshooting network issues by isolating problems to specific layers.
