In two-tier client server architecture, the client is usually.
In two-tier client-server architecture, the client is usually a fat client.
Client-server architecture:-
Client-Server Architecture is a shared architecture system where loads of client-server are divided. The client-server architecture is a centralized resource system where the server holds all the resources. The server receives numerous performances at its edge for sharing resources to its clients when requested. Client and server may be on the same or in a network. The server is profoundly stable and scalable to return answers to clients.
Two-tier architecture:-
In the two-tier architecture, the client and server have to come in direct incorporation. If a client is giving an input to the server there shouldn’t be any intermediate. This is done for rapid results and to avoid confusion between different clients. For instance, online ticket reservations software use this two-tier architecture.
Fat client:-
A fat client is a computer in client-server architecture or networks, that typically provides rich functionality independent of the central server.
