Final answer:
True, the allocation of application-level tasks between clients and servers is the key feature of a client/server architecture. The server manages resources and services while the client handles user interaction and may perform some processing.
Step-by-step explanation:
The client-server architecture refers to a system that hosts, delivers, and manages most of the resources and services that the client requests. In this model, all requests and services are delivered over a network, and it is also referred to as the networking computing model or client server network. True, the key feature of a client/server architecture is indeed the allocation of application-level tasks between clients and servers. In this structure, the server hosts resources and provides services, such as data management, resource sharing, and file storage. The client is typically a user's device (like a computer or a mobile phone) and is responsible for presenting data to the user and, in some cases, may also handle aspects of processing.
A good example of a client/server architecture can be found in web applications, where a web server serves pages and a browser (client) displays them. It's important for the two to work in harmony for the system to function efficiently, with the server handling the heavy lifting and the client managing the display and interactions with the user.
