- APPLICATION LAYER–
- PRESENTATION LAYER-
- SESSION LAYER-
- TRANSPORT LAYER –
- NETWORK LAYER-
- Data Link Layer –
- PHYSICAL LAYER-
The application layer is very close to the user, this layer runs the software and the program, through this layer, the user gets a user friendly view, through this layer we can run every type of file.
EX – Video File ,Audio File , Image File , Software File
This layer compresses the data and also encrypts the data. It prepares the data for the application layer which can be in any file coding. This layer translates any coding to be user friendly and reaches the application layer.
The session layer sprats data from different application layers and creates a dialog control box to create a session between them.
TRANSPORT LAYER –
This layer is the important layer of the osi layer. This layer provides an end-to-end connection to the data packet and also detects that the connection is reliable or unreliable. The delivery of this data packet was reliable and can be done in a unreliable manner. This layer made an error correction in the data packet before the delivery of the data, after which the delivery of the data packet.
This layer explains the track to manage the two devices among themselves, it was a based path by their address
This layer transfers data from the based path in our network to transfer any data packet. This layer provides connection between other devices using the device’s logical address.
Data Link Layer –
This layer further transfers the data packet using the media address of any device. We also know this media address by the name of MAC Address. This data packet is byte then byte aligned in a frame. Finds but does not improve it.
Ex – Switch, Bridge
This layer depends on the topology of our network, it provides bit to our device and also sends bit to the device. And also receives the bit of the device, it completes the layer wire speed and the speed of the device, it changes the layer bit to voltage and converts it into high-low and low-high.
