Final answer:
The statement is true; the client/server architecture is the most common network architecture, characterized by centralized servers providing services to multiple clients.
Step-by-step explanation:
The statement is true: the most common network architecture is indeed the client/server architecture. In this model, multiple clients (such as laptops, smartphones, and tablets) are able to access services and resources from centralized servers. These services can include access to the web, file storage, email, databases, and more. The client/server model allows for centralized management, updates, and backups, making it efficient and scalable, which is why it has become the predominant form of network architecture in many business and educational environments.
