How can many client devices use the same server at once?

In a client-server architecture, multiple client devices can access a single server simultaneously because the system is designed to handle independent requests from remote processors.1

Unlike older mainframe models where a central computer performed all tasks for dependent terminals, the client-server model distributes processing power. The server acts as a host that waits for incoming requests from various clients, such as personal computers or workstations, and responds to them individually.1

Because the client and server are independent devices, the server can manage databases or other services while the client computers handle user interfaces and local tasks. This allows the server to process multiple requests concurrently, providing a standardized, transparent interface that enables many users to interact with the same resources at the same time.1
