Why does the data communication industry use the layered OSI reference model?

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 layerof the model.

It provides a framework by which changes in functionality in one layer require changes

in other layers.

What are one purpose for segmentation with a bridge?

To add more broadcast domains

To create more collision domains

To add less bandwidth for users

To allow more broadcasts for users
