OSI MODEL tutorials

Application

(Layer 7)

This layer provides a user interface. It supports application for communication over the network SMTP (Simple Mail Transfer Protocol), HTTP (Hyper Text Transfer Protocol), FTP (File Transfer Protocol) work at this layer.

Presentation

(Layer 6)

It performs data Presentation, Compression and Encryption so that it is recognizable by the receiver. For most common computer native format is ASCII (American Standard Code for Information Interchange) while for IBM mainframe itís EBCDIC (Extended Binary Coded Decimal Interchange Code)

Session

(Layer 5)

It Establishes connections, keeps different applications data separate, then terminates them after all the data has been sent. It send syn (Synchronization) packets to establish connection, while receiver send back ack acknowledgement .

Transport

(Layer 4)

data is converted into SEGMENT

Provides reliable transport method, Acknowledgement, error correction and retransmission of data when necessary. It makes sure that sender & receiver communicate at speed they both can handle called flow control i.e. 2 Ghz & 500 Mhz comm @500 mhz

Network

(Layer 3)

Segment converted into PACKET

It adds appropriate network addressing and delivery of packets called Datagrams. It provides logical addressing which router use for path determination.

Data Link

(Layer 2)

Packet converted to FRAME

Combine packets into bytes and bytes into frames. It adds the MAC addresses to frames. It performs error detection not correction.

Physical

(Layer 1)

FRAME converted into BITS

Transmit data on the wire. Moves bits between devices. Specify voltage, wire speed and pin-out of cable. This layer is responsible for actual physical connection between devices. It may use Coaxial,CAT,FO cable or wireless for communication
