Main benefits of layered open systems interconnection model

It is a generic model and acts as a guidance tool to develop any network model.
It is a layered model. Changes are one layer do not affect other layers, provided that the interfaces between the layers do not change drastically.
It distinctly separates services, interfaces, and protocols. Hence, it is flexible in nature. Protocols in each layer can be replaced very conveniently depending upon the nature of the network.
It supports both connection-oriented services and connectionless services.
It helps you to standardize router, switch, motherboard, and other hardware
Reduces complexity and standardizes interfaces
Facilitates modular engineering
Helps you to ensure interoperable technology
Helps you to accelerate the evolution
Protocols can be replaced by new protocols when technology changes.
Provide support for connection-oriented services as well as connectionless service.
It is a standard model in computer networking.
Supports connectionless and connection-oriented services.
Offers flexibility to adapt to various types of protocols

It prevents changes in one layer from affecting other layers. It describes what functions occur at each layer of the model that encourages industry standardization. Dividing network communication process in smaller component makes software development, design, and troubleshooting easier. Standardization of network components allows multiple-vendor development. It allows different types of network hardware and software to communicate. Dividing network in layers make network administrators life easier. They can troubleshoot issue more quickly and effectually by looking in layer that is causing issue rather than finding it entire network. It also makes learning easier.

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...
