Computer Dynamics is a microcomputer software development company that has a 300-computer network. The company is located in three adjacent five-story buildings in an office park, with about 100 computers in each building. The LANs in each building are similar, but one building has the data center on the second floor. There are no other office locations. The current network is poorly designed for its current needs and must be completely replaced. 

Develop a logical design for this enterprise campus that considers the seven network architecture components. There are no other campuses, so you can omit WAN access. 

You will need to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way.
