What are the advantages and disadvantages of host-based networks versus client-server networks?

The main advantage of a host-based network is that it has one point of control or central server and all the messages and information goes via this central server. The disadvantages is that the server has to process all the information and it has to coup with the growing demand of information processing from more and more network applications. The server might become overloaded in this process.

A client-server network is beneficial in the present world because more and more computer networks are moving from centralized mainframe computer server towards Local Area Networks that are based on microcomputers.

The disadvantage of client-server networks is that the data that resides on the network has to be processed by the clients.
