OSI Model VS TCP/IP Model|| Difference Between them
The document outlines the OSI model, which divides network communications into seven layers, detailing each layer's function from the application layer to the physical layer. It compares the OSI model with the TCP/IP model, highlighting key differences such as the number of layers and their reliability. The document also emphasizes the benefits of the OSI model, including improved understanding of complex systems and faster research and development.

Sending data over a network is complex because various hardware and software technologies must work cohesively across geographical and political boundaries. Benefits of OSI Model: 1. Shared understanding of complex systems 2. Faster research and development 3. Flexible standardization

Presentation Layer Translating data from one format to another. Translation, compression, encryption/decryption techniques. Session Layer Manage & maintain interaction between communicating devices. Creating a connection between sender & receiver. Transport Layer Heart of OSI Model. Segmentation occurs in this layer. Uses TCP/IP or UDP protocol for faster transmission. Network Layer Manages devices addressing, routing and tracks the location of the devices. Data units are packets. Data Link Layer Reliable transmission of data, Sending error free data, check the frames are damage or not. Physical Layer Transmit & receive individual bits from one node to another.

Implementation of OSI Model Reference Model. It has only four layers. It has seven layers. It is model around which internet is developed. It is a theoretical model. It is more reliable. It is less reliable. TCP/IP follows horizontal approach. OSI follows a vertical approach. Protocol dependant standard. Protocol independent standard.
