Why does the data communication industry use the layered OSI reference model (Choose two.)（）。
A
It divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting.
B
It enables equipment from different vendors to use the same electronic components, thus saving research and development funds.
C
It supports theevolution of multiple competing standards, and thus provides business opportunities for equipment manufacturers.
D
It encourages industry standardization by defining what functions occur at each layer of the model.
E
It provides a means by which changes in functionality in one layer require changes in other layers.
