1 Why is the OSI model useful in network design and assessment? C It combines specific networking tasks into a complex format.

It defines the four lower layers, which standardize applications supported within the model.

It is used during troubleshooting to focus on the entire networking process instead of a single layer.

It divides networking communications into multiple processes that are smaller and more manageable.
