What is the minimum number of computers required to create a network?

To create a network, you need at least two computers to establish a connection between them. A network fundamentally consists of multiple devices that can communicate with one another. When there is only one computer, it cannot communicate or share resources with any other device, thereby not forming a network.

With two computers, you can set up basic networking protocols, allowing them to share data, resources, and connectivity. This foundational requirement highlights the essence of networking: the interaction between devices. More than two devices can enhance the complexity and functionality of the network, but the minimal setup to achieve the concept of networking begins with two.
