What Is The Full Form Of OSI Model?
The Full Form Of OSI Model is a Open Systems Interconnection
The OSI is a model that defines the communication duties of a computing system without consideration to its underlying internal structure and technology. This model was produced by the International Organization for Standardization (ISO) in 1984. It is a reference model for how applications communicate over a network.
The OSI model can be recognized as a common language for computer networking. It divides into 7 abstract layers:
Layers of OSI Model
- The Physical Layer
- The Data Link Layer
- The Network Layer
- The Transport Layer
- The Session Layer
- The Presentation Layer
- The Application Layer
- It is the theoretical model which facilitates the different communication methods to communicate utilizing the network.
- Taking the whole responsibility to transfer the data packets between network devices.
- It comprises seven layers, and each layer works independently to achieve desirable results.
- The best part about this model is, it includes seven layers, and these layers are independent. And thus, shifts in one layer do not affect the other layers.
- It is secure and flexible.
- It has the ability to deal with both connectionless and connection-oriented services.
- Designing, development and maintenance of the software is easy because the model split the communication process into small sections.
- At times, the whole process becomes too complicated.
- The initial implementation is slow and expensive.
- It is completely a hypothetical model and overlooks the presence of devices and technologies. Hence, its practical implementation is somewhat restrained.
