Why does the data communication industry use the layered OSI reference model?
- It divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting.
- It enables equipment from different vendors to use the same electronic components, thus saving research and development funds.
- It supports the evolution of multiple competing standards and thus provides business opportunities for equipment manufacturers.
- It encourages industry standardization by defining what functions occur at each layer of the model.
Answer: Option
Explanation:
The main advantage of a layered model is that it can allow application developers to change aspects of a program in just one layer of the layer model's specifications.
Advantages of using the OSI layered model include, but are not limited to, the following:
It divides the network communication process into smaller and simpler components, thus aiding compo- nent development, design, and troubleshooting;
it allows multiple-vendor development through standardization of network components;
it encourages industry standardization by defining what functions occur at each layer of the model;
it allows various types of network hardware and software to communicate;
and it prevents changes in one layer from affecting other layers, so it does not hamper development.Discussion:
