Explain the OSI model with examples of each layer.

Solutions

Expert Solution

The OSI is open system interconnection model. It is a concept of framework that describes the activities or functions of telecommunication system. There are 7 layers in OSI model let us discuss each
Layer 7: Application
An application layer is for shared communication protocols and interface methods used by hosts in communication networks. It is used in standard models

Layer 6: Presentation
It is the lowest layer which involves data structures and presentation.

Layer 5: session
It provides mechanism for opening, closing and managing a session between end-user application processes.

Layer 4: Transport
It deals with end to end communication over a network. It provide logical communication between application processes and other network components.

Layer 3: Network
In this data is transferred in the form of packets via logical paths.

Layer 2: Data Link
It is a protocol layer for a set of telecommunication protocols.

Layer 1: Physical
It deals with thephysical connectivity of two different stations. It layers defines hardware, cabling, wiring.

The Open Systems Interconnection (OSI) Layer 3 (Network Layer) is one   of the layers that performs packet segmentation. The OSI Layer 3 is   roughly equivalent to the Internet Layer of the Transmission Control   Protocol/Internet Protocol (TCP/IP) model, and Layer 4 (Transport Layer) of the OSI model is roughly equivalent to the Host-to-Host layer of the TCP/IP model. The above two layers perform network segmentation. Based on the above information, answer the following questions: Describe in detail how packets are segmented...
