The document discusses different types of computer networks based on connectivity and geographic scope. It describes private networks that are controlled by a single entity and public networks that can be accessed by anyone but are run by an organization. It also outlines centralized, distributed, and hybrid network structures. The document then categorizes networks into personal area networks (PANs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs) based on their geographic range. It provides examples and uses of each type of network.
