Which type of network would be most appropriate for a business with three employees and a manager sharing documents in the same office space?

The most appropriate choice for a business with three employees and a manager sharing documents in the same office space is a peer-to-peer network. This type of network enables each computer to communicate directly with others on the same network without the need for a dedicated server. In a small office setting, such as the one described, a peer-to-peer network allows employees and the manager to easily share files, access documents, and collaborate directly.

This choice is practical because it does not require complex networking equipment or configurations, making it cost-effective and straightforward for a small team. Each participant can act as both a client and a server, facilitating file sharing and communication without the overhead associated with managing a server-based infrastructure.

Other network types, such as a wireless network in infrastructure mode, while effective for broader coverage and mobility, may introduce unnecessary complexity for a small office situation where direct document sharing is the primary requirement. A domain-based LAN would typically be used in larger organizations where centralized management of resources and user authentication is necessary, which is not suitable for a small setup. A campus area network is designed for interconnecting multiple buildings or larger areas, which is unnecessary and more than what is needed in this specific case. Thus, the peer-to-peer network is the most tailored solution
