What are the two major ways to implement a client server network?
-
First/last
-
High/low
-
Thick/thin
-
Client/workstation
Correct Answer
A. Thick/thinExplanation
The two major ways to implement a client-server network are thick and thin. In a thick client-server network, the majority of the processing power and resources are located on the client side, while the server primarily handles data storage and retrieval. This type of network allows for more control and flexibility on the client side but requires more powerful hardware. In contrast, a thin client-server network offloads most of the processing and resources to the server, with the clients acting as simple terminals. This approach reduces the hardware requirements for clients but may result in decreased performance and limited functionality.Rate this question:
